BACKGROUND

Field of the Invention

[0001] This invention relates to solar energy concentrating system where reflectors are kept at static position and solar cells are moved to capture maximum solar radiation.

Description of Related Art [0001] With the worldwide population growing steadily, demand for energy scales up. This intensifying demand takes place in a time when traditional sources of energy face particular pressure due to the scarcity of resources as well as stronger calls by customers and households for energy sources that minimize the negative environmental impact. To cope with this conundrum, solar energy constitutes an attractive and reliable alternative based on a readily available energy source— solar light. In this context, there is a need for a better use of solar energy, more specifically for means that provide a more efficient concentration of solar radiation and its conversion at low costs. In addition, by dispensing with distribution costs, means for local concentration and conversion of solar energy reduce overall costs and make solar power more affordable for households and other small units of real estate owners.

[0002] Over the years, solar energy research has helped develop systems that have improved efficiency and are more economical. However, a dearth of information, materials, complexity, and manufacturing skills remain an impediment to large-scale production and utilization of this abundantly available energy source for household supply. Due to lack of economic incentives and technical means, access to this technology is particularly difficult in some rural regions of developing countries. One way of overcoming obstacles related to lack of technical knowledge involves reducing the number of complex manipulations or maintenance operations by users.

[0003] The typical solar concentrators can be classified according to several aspects. The ones relevant for the purpose of the present description are the kind of focusing employed (point, line or area), positional adjustability of the reflectors involved in the concentration process (fixed or tracking devices) and characteristics of the conversion systems— solar panels, heat absorbers, or both. [0004] Compared to non-concentrating solar energy conversion systems, the sunlight concentrated toward a photovoltaic solar panel is magnified. As a result, on the one hand, solar energy concentrator systems benefit more than non-concentrating solar energy systems from using relatively more performing solar panels. Efficiency improvements are fast in the field of photovoltaic solar cells, and solar energy concentrator systems thus benefit particularly from an easy upgrade to a more efficient solar panel. On the other hand, more heat is gathered at the target area of a concentrator system than in a non-concentrating solar energy system. Heat negatively affects the efficiency of photovoltaic solar panels, entailing that efficient heat transfer or cooling systems have a special importance in solar energy concentrator systems that rely on photovoltaic solar panels as their receivers.

[0005] Several examples of solar energy concentrators are found in the prior art. These apparatuses feature several inconveniences, such as complexity and cost. Furthermore, many of those designs do not easily lend themselves to installation in the scale contemplated for supplying a household. For example, the structural weight and design of even a small-sized, movable dish reflector complicates its deployment atop a house roof, in addition to making it vulnerable to wind damage. Sidestepping these problems by reducing the scale of the dish reflector seriously limits the amount of energy this kind of concentrator may yield.

[0006] Based on the end application, different types of solar concentrators are employed to achieve optimum results. In the specific scope of the present invention— continual collection of concentrated solar radiation reflected to a focal area in order to generate energy for supplying a standard household or small real estate unit— the performance of state of the art solar concentrators is suboptimal, or the system is too expensive or complex for use by a standard household or in a small real estate unit.

[0007] Line focus systems of solar energy concentration, as in U.S. Pat. No. 5,374,317 (Lamb et al.) or U.S. Pat. No. 4,065,053 (Fletcher), typically perform less in concentrating solar radiation than area or point focus. Moreover, line focus systems tend to be bulky. The size and shape of these bulky systems entail higher manufacturing costs (for materials) and require a larger area for their installation. These characteristics make line focus systems rather inadequate for implementation for a standard household or small real estate unit. Conversely, point focus, as in U.S. Patent Publication No. US20110088684 Al (Tuli) and others, typically requires multiple sets of concentrating reflectors. A substantially high degree of precision is thus required, both in terms of mechanical adjustments of the reflectors and in terms of data analysis and predictions.

[0008] For instance, as in U.S. Pat. No. 6,530,369 (Yogev et al.), concentrators comprising a central receiver tower are typically employed in large scale applications for electricity generation. These embodiments require vast real-estate for proper deployment and are thus not economical or convenient for small- and medium-scale applications. Parabolic dish concentrators with continuous surfaces, as in U.S. Pat. No. 7,435,898 (Shifman), entail limitations such as the prohibitive manufacturing costs associated with compound and complex reflector curves as well as expensive mirror substrates.

[0009] Most prior art applications of solar energy concentrators involve a primary concentrating reflector that is movable, as can be found in U.S. Pat. No. 8,471,187 (Kinley). In addition to cost issues and physical vulnerabilities inherent to a movable primary concentrating reflector, the moving components need to each be associated with a tracking system and a moving mechanism for the moving feature to improve the system’s performance. When integrated to the primary concentrating reflector, these requirements and the associated costs and vulnerabilities are multiplied because primary concentrating reflectors are typically made of numerous parts.

[0010] In U.S. Patent Publication No. US20110088684 Al (Tub) by the same inventor, a solar energy concentrator is disclosed whereby rays of the sun are reflected and concentrated to a heat absorber by a combination of a fixed primary concentrating reflector and a movable secondary redirecting reflector. The secondary redirecting reflector is ball-pivotally connected to an elongated arm that is itself ball-pivotally connected to a stationary surface. Alternatively, there is no secondary redirecting reflector, and the heat absorber is connected at the distal end of the elongated arm. Unlike in the present invention, this system uses a heat absorber instead of a solar panel. The solar energy concentrator disclosed therein includes several physical components that potentially block the solar radiation reflected by the primary concentrating reflector before it can be collected by the receiver. Moreover, the supporting components are in itself vulnerable to wear and tear, wind and other weather conditions, thus necessitating a suboptimal retraction of the elongated arm to prevent damages to the structural integrity of the elongated arm when wind conditions are threatening. The elongated arm can also be vulnerable when the position of the sun requires the elongated arm to be sharply inclined in order to receive solar radiation redirected by the primary concentrating reflector.

[0011] There is accordingly a need for an improved solar concentrating system that overcomes the limitations associated with using complex or suboptimal structures or assemblies that require a high degree of skills. Moreover, there is a need for an improved solar concentrating system wherein the costs associated with manufacture and deployment, which are prohibitive with respect to traditional solar concentrating systems, are minimized so that it is affordable and attractive for use by small- and medium-scale household use.

[0012] It is therefore an object of the present invention to disclose a small- or medium- scale, dimensionally-adaptable solar concentrator system featuring high energy conversion efficiency, providing area focus with low building and operational costs.

BRIEF SUMMARY OF THE INVENTION

[0002] The invention described herein is designed to work as solar energy generating system having multiple solar panels. Multiple solar panels are arranged in arrays of rows, wherein each row has multiple solar panels. Each of the solar panel has two reflecting troughs. Each reflecting troughs are identical in shape and orientation. Further, each one of the reflecting trough receives sunlight and focus them on to a high efficiency solar cell. The length of the high efficiency solar cell is same as that of the reflecting troughs. Each high efficiency solar cell is kept at focus of its reflecting trough using strings attached to a structure of the panel. Each of the solar panel is kept at an angle with the ground. The angle is preferably kept same as that of the earth’s angle of inclination to its own axis. The structure of each of the solar panels has at least two side walls that are used to keep the troughs at their position. The side walls are also kept at an inclination from a base plate so as to create a tub like structure within which the reflecting troughs are kept. Each of the solar energy panels has a glass top that allows sunrays to pass through it and hit the reflecting troughs. The solar cells are placed beneath the glass top and on top of the reflecting troughs. Each of the solar cells can be moved by the strings to keep the solar cells in focus. The strings are attached to the sidewalls of the panel. When multiple solar energy panels are placed in arrays, difference between solar energy panels arranged in adjacent rows are kept such that one row of solar energy panels does not cast a shadow on another. Further, the high efficiency solar cells within a panel are not connected to each other electrically. However, when multiple panels are kept in a row, each of the high efficiency solar cells are connected in series to its corresponding high efficiency solar cell present in its adjacent panel in the same row. Thus a single row of panels has two rows of serially connected high efficiency solar cells. When multiple rows of panels are present, it creates twice the number of serially connected solar cells than the number of rows of the panels. All the serially connected rows of solar cells are then connected to each other as per parallel connection. Further, each one of the high efficiency solar cells is provided with a heat sink on top of it.

[0003] As per another embodiment of the present invention, an elongated low efficiency solar cell can be placed on top of each of the heat sink to capture sunrays that do not reach the reflecting troughs. The heat sink, the low efficiency solar cell and the high efficiency solar cell are kept at pyramidal structured way with high efficiency solar cell forming the base of the pyramid, followed by the heat sink and the low efficiency solar cell. Such a structure helps in reducing amount of shadow falling on the reflecting troughs placed beneath the solar cells.

[0004] As per yet another embodiment of the present invention, small fans or blowers are present inside the sidewalls to blow cold air into the heat sink so as to reduce the temperature of the solar cells. As per yet another embodiment of the present invention, after each row of panels, a pair of terminating units is provided, one at each end of a row. The terminating units are just two rows of troughs that are aligned as per the troughs in the panels of the row, and are present to direct sunrays towards the high efficiency solar cells, during morning and evening.

DETAILED DESCRIPTION OF THE INVENTION

[0054] The invention described herein is designed to work as solar energy generating system having multiple solar panels. Multiple solar panels are arranged in arrays of rows, wherein each row has multiple solar panels. Each of the solar panel has two reflecting troughs. Both the reflecting troughs are identical in shape and orientation. Further, each one of the reflecting troughs receives sunlight and reflects them on to a high efficiency solar cell. Thus, a solar panel have two reflecting troughs and two solar cells. The high frequency solar cell is an array of serially connected solar cell units. The length of the high efficiency solar cell is nearly same as that of the reflecting troughs. Each high efficiency solar cell is kept at a height from the reflecting troughs, where it receives maximum amount of reflected sunrays throughout a year. The position of the solar cells should be such that they remain near the focus so that the solar cell can receive most of the sunrays reflected back by the reflecting trough. Each high efficiency solar cell is kept at that position using strings. Each of the solar panel is kept at an angle with the ground. The angle is preferably kept same as that of the latitude tilt of the geographical location at which the solar panel is placed. The structure of each of the solar panels has at least two side walls that are used to keep the troughs at their position. The side walls are kept at an inclination from a base plate so as to create a tub like structure within which the reflecting troughs are kept. The angle at which side walls are from the base plate is 90°+23.5°, and 90°-23.5°. The angle of inclination of the sidewalls is kept same as that of earth’s inclination to its own axis. This inclination of the side walls causes maximum sunrays to enter the solar panel throughout a year. Each of the solar energy panels has a glass top that allows sunrays to pass through it and hit the reflecting troughs. The solar cells are placed beneath the glass top and on top of the reflecting troughs. Each of the solar cells can be moved in a two dimensional plane by the strings to keep the solar cells at optimal positions where the solar cells receive maximum reflected sunrays throughout a year. The plane should be such that the solar cell remains near the focus of the reflecting trough. The strings are attached to rollers present within the sidewalls of the panel. When multiple solar energy panels are placed in arrays, difference between solar energy panels arranged in adjacent rows are kept such that one row of solar energy panels does not cast a shadow on another, at any time of a year. Further, the high efficiency solar cells within a panel are not connected to each other electrically. However, when multiple panels are kept in a row, each of the high efficiency solar cells are connected in series to its corresponding high efficiency solar cell present in its adjacent panel in the same row. Thus a single row of panels has two rows of serially connected high efficiency solar cells. When multiple rows of panels are present, it creates twice the number of serially connected solar cells than the number of rows of the panels. All the serially connected solar cells are then connected to each other as per parallel connection. Further, each one of the high efficiency solar cells is provided with a heat sink on top of it. As per another embodiment of the present invention, an elongated low efficiency solar cell can be placed on top of each of the heat sink to capture sunrays that do not reach the reflecting troughs. The heat sink, the low efficiency solar cell and the high efficiency solar cell are kept at pyramidal structured way with high efficiency solar cell forming the base of the pyramid, followed by the heat sink and the low efficiency solar cell. Such a structure helps in reducing amount of shadow falling on the reflecting troughs placed beneath the solar cells. As per yet another embodiment of the present invention, small fans or blowers are present inside the sidewalls to blow cold air into the heat sink so as to reduce the temperature of the solar cells. As per yet another embodiment of the present invention, after each row of panels, a pair of terminating units is provided, one at each end of a row. The terminating units are just two rows of troughs that are aligned as per the troughs in the panels of the row, and are present to direct sunrays towards the high efficiency solar cells, during morning and evening. One of the primary embodiments of the present invention is that the solar panels and the reflective troughs are kept motionless during operation of the solar energy generating system. The present invention and all its embodiments will be described in details below.

[0055] Fig. 1A is a perspective view of the solar energy generating system 100 having multiple solar panels 1. Also, it must be noted that the solar panels 1 are also referred as panels throughout the detail description of the invention. For the sake of understanding only, two rows of panels 1 are shown having only two solar panels la and lb in each row. However, multiple panels l(la and lb) can be placed adjacent to each other in a row and multiple such rows can be present in the solar energy generating system 100. Please note that, in the figures of the present invention, a, b, c...z are used to denote same components present in different rows of the solar energy generating system 100. Thus, panels 1 present at two adjacent rows are depicted as la and lb and so are their components. Each one of the solar panels 1 has two reflecting troughs 2 and 3 that reflect sunrays to two solar cells 4 and 5. The solar cells 4 and 5 are high efficiency solar cells. Two sidewalls 6 and 7 are present at to opposite side of the reflecting troughs 2 and 3, so as to keep the reflecting troughs 2 and 3 at their position. The sidewalls 6 and 7 also act as a support over which a glass top 8 is provided. The sidewalls 6 and 7 are also kept at an angle with a base plate 10 of the panel 1 so as to create a tub like structure. The structure of the panels 1 can also be called as trapezoidal structure. The sidewalls 6 and 7 are kept at an internal angle of 90°+23.5° with respect to the base plate 10, wherein the sidewalls bent outwards in that angle from the base plate 10. The sidewalls 6 and 7, base plate 10 and top glass 8 forms a structure of the panel 1. The solar cells 4 and 5 are present between the reflecting troughs 2 and 3, and the glass top 8, and held at their position by multiple strings (not shown). The reflecting troughs 2 and 3 are made up of one plastic fdm that is vacuum moulded to create a complex semi-circular structured mirror surface. As per a preferred embodiment, the shape of the reflecting troughs 2 and 3 are exactly semi-cylindrical. Also, as per the preferred embodiment of the present invention, a plastic sheet having a reflective surface is pushed inside the panel structure to form a bent mirror surface that act as the reflecting trough 2 or 3. However, other types of complex semicircular structured mirrors can also be used. The mirror surface is kept facing the sun so that most of the sunrays hitting the mirror surface is reflected back. Each of the solar cells 4 and 5 are arranged to be at a plane that can collect most of the sunrays reflected back by the reflecting troughs 2 and 3, throughout a year. It should be noted that the solar cells 4 and 5 should not be at exact focus point of the reflecting troughs 2 and 3. Being at focus can cause too much concentrated sunrays to hit the solar cells 4 and 5, and cause permanent damage to them. This would be explained further in details later. As shown in the figure 1A, each one of the panels 1 is kept at an angle with respect to the ground. This angle is same as the latitude tilt at which the panels are placed. Hence, at equator, the panels will be lying flat on the ground, whereas at tropic of cancer, the panels will be lying at 23.43695° (approximately 23.5°). Also, the space between each row of panels 1 is kept such that a row of panels 1 does not obstruct sunrays from reaching the panels 1 placed in adjacent row, at any time of the year. This will be further explained using a side view of the solar energy generating system 100 shown in Figure IB.

[0056] Figure IB is a side view of the solar energy generating system 100 viewed from Y axis. The panels 1 are kept at an inclination with respect to the ground. Angle of the inclination is kept same as that of the latitude tilt of the geographic location at which the panels 1 are placed. This is further explained using Figure 1C and ID. Fig 1C explains inclination of earth’s axis which causes sunrays 101 to hit at an angle. Earth’s inclination is 23.5°, with respect to its own axis. This causes the sunrays 101 to hit the earth surface at that specific inclination. As earth’s revolves round the sun, the tilting of earth’s axis causes formation of seasons. This means that at different locations on its orbit around the sun, different parts of the earth are tilted towards the sun, and the part that is tilted toward the sun is the part that is having summer. If earth’s northern hemisphere is tilted toward the sun, the northern hemisphere receives the most direct rays of the sun (that is, the angle of incidence of sunrays is higher), and it is summer in the northern hemisphere. If earth’s southern hemisphere is tilted toward the sun, the southern hemisphere receives the most direct rays of the sun (that is, the angle of incidence of sunrays is higher), and it is summer in the southern hemisphere. Thus, on June solstice, when earth’s northern hemisphere is maximum tilted towards sun, sunrays hit Tropic of Cancer (23.5° N latitude) perpendicularly, Equator at an angle of 113.5° (90° +23.5°), and Tropic of Capricorn (23.5°S latitude) at an angle of 137° (90°+23.5°+ 23.5°). During December Solstice, the exact opposite happens. Thus, depending on various seasons, angle at incidence of sunrays at equator varies from +23.5° to -23.5°. Thus, any specific location in the northern hemisphere of earth, during winter will receive sunrays lOlb at angle which is equal to the sum total of latitude of that location plus earth’s angle of inclination plus 90°. Thus at equator during winter in northern hemisphere, the angle at which sunrays 101 will hit the equator will be 113.5 °(0° + 23.5° + 90°). Similarly, during winter, tropic of cancer will receive sunrays 101 at an angle of 137° (23.5° + 23.5° + 90°). During summer in the northern hemisphere, the northern hemisphere will be closer to the sun and thus, will receive sunrays 101 more directly. The angle at which the sunrays 101 will hit the surface at an angle which is sum of the latitude of the location minus earth’s angle of inclination plus 90°. Thus, during summer, tropic of cancer will receive sunrays 101 at an angle of 90° and equator will receive sunrays 101 at angle of 66.5°. Hence, overall variation at which sunrays 101 hits a location varies between +23.5° to -23.5°. Thus, to reduce the angle at which sunrays 101 fall on a particular location, panels should be placed at an angle equal to the latitude tilt of that location. Fig. ID illustrates a panel 1 placed at 23.5° with respect to ground on tropic of cancer. As earth’s inclination causes sunrays 101a to hit the earth’s surface perpendicularly during summer, placing a panel 1 at that latitude tilt angle causes sunrays to hit the panel 1 at an angle of 66.5°. As a result, the sunrays hit the reflecting troughs 2 and 3, at an angle of 66.5° during summer. At winter, the northern hemisphere will be further away from sun and hence, sunrays 101b will hit the tropic of Cancer at an angle of 137°. Having the panel 1 paced at the latitude tilt angle means, the sunrays 101b will hit the panel at an angle of 113.5°. The sunrays 101a that hit the northern hemisphere during summer are called as summer sunrays and the sunrays 101b that hit the earth’s northern hemisphere during winter are called winter sunrays. Thus, having panels 1 at latitude tilt angle makes sunrays 101 to vary between +23.5° to -23.5° throughout a year. Now, going back to Figure IB, as multiple rows of panels 1 are arranged in rows, the distance between panels 1 placed in adjacent rows should be such that the shadow of panel lb placed in one row does not fall on panel la placed in adjacent row. During Equinoxes, sunrays 101 will hit the panels 1 perpendicularly. In the Fig. IB, sunrays 101a represent sunrays 101 hitting the panels 1 during summer and sunrays 101b represents sunrays hitting the panels during winter. In case panels 1 of two adjacent rows are placed very near to each other, panel lb will block winter sunrays 101b from reaching panel la. Thus, amount of sunrays 101 received by panels la will be reduced, which in turn will reduce solar energy generated by the panels la placed in that row. In case the panels la and lb are placed far away from each other, sunrays 101b will fall on the ground and will be not be converted to solar energy. Hence, the distance d between adjacent rows of panels 1 is predetermined so as to convert most of the sunrays falling on the solar energy generation system 100 without increasing the overall size of the solar energy generating system 100. The distance d should be such that the winter sunrays 101b which hit at winter should fall on the reflecting trough 3a of the adjacent row. Thus, the panel la will always receive sunrays 101 throughout a year, even though some of the sunrays 101a that hit during summer will fall in between two rows of panels 1 and will get wasted.

[0057] Fig. IE is a top view of the solar energy generating system 100 with multiple rows of panels 1, each row having multiple panels 1, as seen from Z axis. As explained earlier solar panels 1 placed in adjacent rows will have suffix a,b,c...z. Similarly, solar panels 1, placed in a row will have ί,ΪM''·..h suffix as shown in the figures of the present invention. Also, it must be noted that the number of panels 1, present in each row and the number of rows present in the solar energy generating system 100 shown in the figures of the invention is merely a non-limiting example and can be easily altered by any one ordinary skilled in the art. [0058] Fig. IF is a side view of a reflecting trough 2 and solar cell 4 as viewed from Y axis. Sunrays hitting the reflecting trough 2 get reflected back to a focus O. The solar cell 4 has a width of w and can be placed at a plane above the reflecting trough 2. Fig. 1G explains distribution of energy at various planes across the width w of the solar cell 4. When solar cell 4 is placed on the focus O, it will receive concentrated sunrays at a location within the width w of solar cell 4. Thus a spike of solar energy will be present at particular location within the solar cell 4. Such a spike of energy can cause the solar cell 4 to bum out and get damaged. So solar cells 4 are kept at planes A-Al or plane B-Bl that are very close to the focus O but not exactly at the focus O. At plane A-Ai reflected sunrays are spread out along the entire width w of the solar cell 4. As evident from figure IF, even at plane B-Bl, reflected sunrays will be distributed throughout the entire width w of the solar cell 4. Hence, at Fig. 1G reflected sunrays are more evenly spread out across the entire width w of the solar cell 4. Similarly, when the solar cell 4 is kept at the plane C-Cl, it can only receive a part of the reflected sunrays. This is evident from the Fig. 1G. Further, on Fig 1G, part of the solar energy that falls beyond the width w will get wasted and is shaded in the graph. As evident from the figure, the amount of solar energy that gets wasted is significantly high when the solar cell 4 is paled on plane C-Cl. Thus, the solar cell 4 should be placed either on plane A-Al or B-Bl to capture most of the reflected sunrays. Within a plane too, location of the solar cell 4 should be such that it receives maximum amount of evenly distributed reflected sunrays across its width w. Thus, the solar cell 4 should be near the focus O but not exactly at the focus O of the reflecting trough 2.The solar cell 4 is moved within a plane across various locations to capture sunlight throughout a year. The locations within a plane should be selected such that the solar cell4 receives maximum sunlight throughout a year, without being in exact focus anytime of the year. The locations should be such that at any day of the year, sunlight is spread evenly across the entire width w of the solar cell 4. [0059] Fig. 2A is a side view of a panel 1 used in the solar energy concentrating system 100 as per one of the embodiment of the present invention. Please note that Fig. 2A illustrates a side view of a panel 1 when viewed from Y axis, wherein the panel 1 is placed flat on the ground. Each panel 1 comprises of two reflecting troughs 2 and 3 that focuses most of the sunrays on to two focuses. Two high efficiency solar cells 4 and 5 are placed as close to the focuses, such that solar cell 4 can collect most of the sunrays reflected from the reflecting trough 2 and solar cell 5 can collect most of the sunrays reflected from reflecting trough 3. Each of the two reflecting troughs 2 and 3, has complex semi-circular shaped mirror surfaces that are aligned to face sunrays and reflect them back on to its corresponding solar cell 4 or 5. The solar cells 4 and 5 are high efficiency solar cells that convert most of the concentrated sunrays falling on them to solar energy. Each of the solar cells 4 and 5 should be placed in position close to their respective focus so as to collect most of the sunrays reflected back from their corresponding reflecting troughs 2 and 3. It must be noted that it the solar cells 4 and 5 is not always on the focus of their respective reflecting troughs 2 and 3, but is kept near the focus so as to capture most of the sunrays reflected back. Hence, at some days of a year, some of the reflected sunrays from the troughs 2 and 3 will not fall on any solar cell 4 and 5, but the position of the solar cell4 and 5 should be chosen such that amount of such sunrays is negligible. Also, each of the high efficiency solar cells 4 and 5 themselves comprises of multiple solar cell units that are connected to each other in a serial connection to form each one of the elongated solar cells 4 and 5. The reflecting troughs 2 and 3 are kept in their position by two sidewalls 6 and 7. The two sidewalls 6 and 7 are connected to a base plate 10 that holds the entire structure together. As per one of the embodiment of the present invention, the sidewalls 6 and 7 are made up of glass and coated with anti-reflective coating. The solar cells 4 and 5 are kept in their position of collecting maximum reflected sunrays by strings 9 that run across at multiple places throughout the entire length of the panel 1. The strings 9 run from sidewall 6 to sidewall 7 holding the solar cells 4 and 5. Each one of the strings 9 can be a single string or multiple strings connected to each other and the solar cells 4 and 5. The objective of the strings 9 is to hold the solar cells 4 and 5 on their ideal positions throughout a year, without obstructing sunrays from reaching the reflecting troughs 2 and 3. For that purpose, the strings 9 should be kept as narrow as possible. A glass top 8 is placed on top of the sidewalls 6 and 7 that act as a cover for the panel 1. The glass top 8 is coated with anti-reflective coatings to allow sunrays to pass through it without any alteration. The glass top 8 is placed in such a way that it forms a cover for both the reflecting troughs 2 and 3, and the solar cells 4 and 5 remain in space between the glass top 8 and the reflecting troughs 2 and 3. The glass top 8, the sidewalls 6 and 7, along with the base plate 10 forms a rigid structure for the panels 1. One of the most important aspects of the present invention is that the sidewalls 6 and 7 are kept at an inclination of 23.5° with the base plate 10, so as to create a tub like structure for the panels 1. Such a structure of the panels 1 helps in reducing the overall size of the compact solar energy generation system 100 without causing any reduction in the amount of sunrays getting converted to solar energy. This is further explained using Fig 2B. The sunrays during summer 101a will hit at an angle of 90°+23.5° with respect to the panel 1. Thus, a small portion 101ai of the summer sunrays 101a can get obstructed by the sidewalls 6 from hitting the reflecting trough 2, in case the sidewall 6 is kept perpendicular to the base plate 10. Perpendicular position of the sidewall 6 is shown by the dotted line 6 . Similarly, during winter when sunrays 101b hits the panel 1 at an angle of 90°- 23.5°. Thus, during winter, a small portion 101bi of it can get obstructed by the sidewall 7 from hitting the reflecting trough 3, in case the sidewall 7 is kept perpendicular to the base plate 10. Perpendicular position of the sidewall 7 is shown by the dotted line

This is true for all the panels 1 and thus, may cause huge loss of sunrays. Having sidewalls 6 and 7 at angle of 23.5° away from their perpendicular position with respect to the base plate 10, allows the small portions of summer sunrays lOlai and winter sunrays lOlbi to hit the reflecting troughs 2 and 3. Thus, the sidewalls 6 and 7 are kept at an angle of +23.5° and - 23.5° respectively from a perpendicular position, so as to capture maximum sunrays 101 both during summer and winter. As per yet another embodiment of the present invention, the sidewalls 6 and 7 are made up of transparent glass. Even then, the sidewalls 6 and 7 are kept at the angles described above. Fig. 2C illustrates a perspective view of the solar energy generation system 100 with two panels la and lb, with strings 9 holding the solar cells 4 and 5. Fig. 2D is a top view of the solar energy generation system 100 with multiple panels 1 arranged in multiple rows and each having strings 9 to hold their respective solar cells 4 and 5.

[0060] Fig. 3A-3B illustrate a side view of a comer between the sidewall 6 and the glass top 8 of the panel 1, as seen from Y axis. The Fig. 3A shows a part of the panel 1 with part of the reflecting trough 2, part of the glass top 8, and part of the string 9 holding a solar cell 4. As shown in the fig. 3A, a part 101b of the winter sunrays 101b is obstructed by part of the sidewall 6 and part of the glass top 8 forming the comer. Fig. 3B shows a comer between the sidewall 6 and the glass top 8 of the panel 1 as per yet another embodiment of the present invention, where a part of the comer is chopped. To allow maximum winter sunrays 101b to pass, edge portion 601 of the sidewalls 6 and edge portion 801 of the glass top 8 are sliced. The angle at which the portion 601 is sliced from the sidewall 6 should be 23.5° + 23.5°, so that the comer between the sidewall 6 and the glass top 8 remains parallel to the winter sunrays 101b. This is explained further using Fig. 3C. The angle of the comer with respect to the glass top is 66.5° (90°-23.5°). This angle is specifically chosen so that the comer remains parallel to the winter sunrays 101b. Thus, as the winter sunrays 101b hit the glass top 8 at an angle of 66.5° (90°-23.5°) and the angle of the comer with respect to the top glass is also 66.5°, the comer becomes parallel to the winter sunrays 108. This, the comer does not cause any obstruction to the winter sunrays 101b to pass through. Thus, as shown in the figure, the angle at which the top glass is chopped should be 23.5°, to have a comer that is parallel to the winter sunrays 101b.

[0061] As per one of the primary embodiment of the present invention, top of the sidewalls 6 and 7 is structured as a clip on which the glass top 8 rests. The comer of the clip portion is chopped at an angle of 23.5° to allow maximum of the winter sunrays 101b to pass through. This is illustrated in Fig. 3D. As shown in the Fig. 3D, the comer of the top of the sidewall 6 is chopped at an angle 23.5°. This causes the comer of the sidewall 6 to be parallel to the winter sunrays l08b. Such a structure of the comer allows maximum winter sunrays lOlb to pass through to the panels 1 placed at adjacent rows.

[0062] Having such a comer with chopped edges, allows part of the winter sunrays 101b that were previously obstructed as shown in Figs. 3A-3B, to pass through. Thus, the distance between the panels 1 placed in adjacent rows of the solar energy generation system 100 is further reduced. This is explained further in Figs. 3E and 3F, which illustrate parts of two rows of panels 1 as viewed from Y axis. In Figs. 3E and 3F, only parts of various components of panels la and lb are shown for easy understanding of the invention. It should not be considered as a limitation of the invention. Fig. 3E shows parts of two rows of panels 1 of a solar energy generation system 100, where the edge portions of the glass top 8 and the sidewall 6 are not chopped off. As a result a small portion 101b of the winter sunrays 101b falling at the comer of glass top 8b and sidewall 6b does not pass on to hit reflecting trough 3a of the panel la. As shown in Fig. 3F, edge portion 801b of glass top 8b, and edge portion 601b of sidewall 6b are chopped off as explained earlier in the embodiment. This allows the small portion lOlb of winter sunrays 101b to pass through to the panel la. Further, to capture the sunrays lOlb , the panel la is kept further close to the panel lb, so that the reflecting trough 3a receives the sunrays lOl bi. Earlier, position of the panel la is shown using dotted lines in Fig. 3F. Thus, evident from the Fig. 3F, distance between two adjacent rows of panels 1 becomes reduced by an amount d . Thus, having chopped edges reduces distance required between two rows of panels 1 of the solar energy generation system 100. As explained earlier, the angle at which the comer of a panel 1 should be chopped is 23.5°. This allows maximum amount of winter sunrays 101b to pass. In yet another embodiment of the present invention, the edge portions of the sidewall 7 and the glass top 8 can also be chopped off in an identical fashion.

[0063] Fig. 4A illustrates side view of another embodiment of the present invention, where a high efficiency solar cell 4 has a heat sink 11 placed on top of it, as viewed from Y axis. It should be noted here that Figs. 4A-4D only show parts of the solar energy generating system 100 and not all the components of the same. It is well known in the art that a portion of sunrays falling on a solar cell gets converted into heat, which increases the temperature of the solar cell. Further, with increase in temperature overall efficiency of a solar cell decreases. As mentioned earlier, each high efficiency solar cell 4 is a serially connected array smaller solar cell units. Hence, temperature of each of the solar cell unit needs to be controlled for full efficiency operation of the high efficiency solar cell 4. Hence, as per one of the embodiment of the present invention, a heat sink 11 is placed on top of the solar cells 4. The fig. 4A shows only one solar cell 4 with a heat sink 11. However, it must be noted that all the solar cells 4 and 5 of all the panels 1 should be provided with a heat sink 11 attached on top of it and running the entire length of the solar cells 4 and 5. The heat sink 11 is attached on top of the solar cell 4 so that it remains in contact with the solar cell 4 and can receive temperature from the solar cell 4. The heat sink can be made up of multiple fins or holes made up of metals like aluminum or other types of alloys. As per the preferred embodiment of the invention, the heat sink 11 has a top aluminum plate 11a, a bottom aluminum plate lib and fins 11c extending between the plates. Fig. 4B illustrates heat sink in more details. The bottom aluminum plate lib is in physical contact with the solar cell 4. Having such a structure of the heat sink 11 creates an I-beam type structure which increases the overall stability of the structure. The bottom aluminum plate lib is kept larger than the top aluminum plate 11a. The fins 11c are designed such that the heat sink 11 forms an isosceles trapezoid shaped structure. The fins 11c are designed in such a way that angle of the side of the isosceles trapezoid are 66.5° (90° - 23.5°). Such a trapezoid shaped heat sink 11 does not cast a shadow on the reflecting troughs 2 positioned beneath the solar cell 4. Fig. 4C illustrates how heat sink 11 with isosceles trapezoid shape does not cast a shadow on the concentrating troughs placed beneath it.

[0064] Fig. 4C illustrates an isosceles trapezoidal structured heat sink 11 and its associated solar cell 4. As shown in the figure, height of the fins 11c of the heat sink 11 are designed in such way that top of the fins 11c have an angle of 66.5° with the bottom aluminum plate lib. This angle is effective to pass portion of the sunrays 101 during winter and summer. As described in earlier embodiments, summer sunrays 101a hit at an angle of 90°-23.5°. Thus in case, the angle of the isosceles trapezoidal shaped heat sink 11 is very essential to pass through portion 101 an of the summer sunrayslOla. Otherwise, the portion lOlaii will be obstructed and will cause a shadow on the underlying reflecting trough 2 (not shown). Similarly, the winter sunrays 101b hits at an angle of 90°+23.5°. Thus, a portion lOlbii of the winter sunrays 101b will get obstructed in case the shape of the heat sink 11 is not trapezoidal or in case the angles of the isosceles trapezoidal shaped heat sink 11 are chosen otherwise. Thus, such a structure of the heat sink 11 causes maximum sunrays 101 (both summer and winter) to pass without causing any shadow.

[0065] Fig. 5 illustrates a side view of yet another embodiment of the present invention, where a low cost solar cell 12 is placed on top of the heat sink 11 that is placed on top of a high efficiency solar cell 4, as viewed from Y axis. As per this embodiment, the high efficiency solar cell 4 can be termed as a primary solar cell where as the low cost solar cell 12 can be termed as a secondary solar cell. As evident from the Fig. 5, the high efficiency solar cell 4 and heat sink 11 blocks a portion 103 of sunrays 101 to reach the reflective troughs 2 placed beneath the high efficiency solar cell 4. Thus, the portion 103 of the sunrays 101 is not converted to solar energy. Placing a low cost solar cell 12 on top of the heat sink 11 helps in capturing a portion 104 of the portion 103 of the sunrays 101 that is not converted to solar energy. Thus, at least a portion 104 of the sunrays 101 that was previously not utilized is converted to solar energy. Thus, overall solar energy generated by the solar energy generation system 100 can be increased. The solar cell 12 being attached to the heat sink 11 helps in controlling temperature of the solar cell 12. Further, the solar cell 12 is of low cost so that overall cost of the solar energy generation system 100 is also not increased too much. However, it must be readily understood that width of low cost solar cell 12 should be smaller that width of the top aluminum plate 11a of the heat sink 11 so that it can comply with the trapezoidal structure described in the previous embodiment. Without that, the solar cell 12 will obstruct sunrays at its edges causing an adverse effect on the efficiency of the system 100

[0066] Fig. 6A-6F illustrate side view of yet another embodiment of the present invention where the solar cells 4 and 5 can move, as viewed from Y axis. This feature is very essential to counter the different angles at which sunrays 101 hit a particular location on earth during various seasons. As explained earlier, summer sunrays 101a hits the panel 1 at an angle of 66.5° (90° - 23.5°) , whereas the winter sunrays 101b hits the panel 1 at an angle of 113.5° (90°+ 23.5°). Thus, with varying seasons, the position at which most of the sunrays 101 will be reflected back by the concentrating trough 2 will also change. This is explained in Fig 6A- 6D. It should be noted here that the various angles mentioned throughout the invention are approximate values. In Fig. 6A, summer sunrays 101a hit the reflecting trough 2 at an angle of 66.5°. The reflecting troughs 2 having a complex semi-circular mirror surface will reflect back the summer sunrays 101a. As a result of the complex semi-circular shape of the concentrating trough 2, reflected sunrays 101a_r are not always focussed at a particular focus point throughout a year. With varying angle of incidence of sunrays throughout a year, sometimes, the concentrating trough 2 reflects back sunrays at focus points and sometimes not. The solar cell 4 (not shown) can be moved in a two dimensional plane only by the strings 9 (not shown). Hence, a plane needs to be identified, where the solar cell 4 can be kept at different positions such that overall distribution of reflected sunrays is highest for a period of one year for the solar cell 4. The width of the solar cell 4 is w and is generally about 1 inch. That plane should be chosen such that solar cell remains in between the glass top 8 and the concentrating trough 2. As shown in Fig. 6A, during summer a position 201 is selected where solar cell 4 (not shown) needs to be placed. However, as explained earlier, the position should be so chosen that the solar cell 4 is not exactly on the focus, which might cause too much heat to be generated on a particular point in the solar cell 4 causing damage. However, the position 201 should be such the most of the reflected sunrays 101a_r on a particular day fall evenly within the 1 inch width of the solar cell 4. Similarly, as shown in Fig 6B, at equinox, when sunrays 101 are perpendicular to the concentrating trough 2, reflected sunrays 101_r are captured by keeping solar cell 4 at location 202. As shown in Fig.6A-6B, the location 201 and location 202 are positions in a same plane and as a result, the amount of reflected sunrays captured by the solar cell 4 (not shown) at two different locations is different. However, the position 202 should also be such that most of the reflected sunrays fall evenly within the width w of the solar cell 4. Similarly, as shown in Fig.6C during winter, sunrays 101b will hit the reflecting trough 2 at an angle of 113.5°, which get reflected back as 101b_r. The solar cell 4 now is placed at location 203, to capture as most of the reflected lOlbr as possible. As evident from the Fig.6C, based on seasons, position of the solar cell 4 (not shown) will shift in location from 201 to 203. All the positions 201, 202, 203 and all the position in between, lie on the same plane. Also, since, the panels 1 are paced at an angle, to capture sunrays at summer and winter, the maximum movement that a solar cell4 has to do is within the range of +23.5° to -23.5°. Also, all the different planes receive same total amount of reflected sunrays throughout a year. At the selected positions, with in the selected plane, the solar cell 4 receives as much radiation as possible evenly distributed along its width w. The positions are such chosen that at every point in the day and on every day of a year, the solar cell 4 receives the maximum solar radiation for that day. Hence, for a particular day, solar cell 4 is positioned at an optimal position within the preselected plane. The solar cell 4 always moves exactly to a desired position where it can receive the maximum solar radiation across its width w, for that day. Thus, at different positions throughout a year, the amount of solar radiation falling on the width w of the solar cell 4 will vary. This is shown in Fig 6D. However, the positions and the plane of the solar cell 4 are chosen such that overall solar radiation falling on the width w of the solar cell 4 is highest for a year. Also, as explained earlier, the solar cell 4 should not be exactly at focus of the concentrating trough 2 at any time of the year. Fig.6D shows a graph of the distribution of reflected sunrays captured by the solar cell 4 (not shown) at three different locations. Since, the solar cell 4 can only move in a plane, the amount of reflected sunrays it receives at every location is not essentially the most of the reflected sunrays. Sometimes, the solar cell 4 is placed such that it can get most, around 95%, of the reflected sunrays. Whereas, on a different day of the year, at that plane, the reflected sunrays cover more area than the width w of the solar cell 4. Thus, solar cell 4 even when it is placed at an optimal position, it can capture only part, around 70% of the reflected sunrays. Thus, the solar panel 4 needs to be moved to optimal positions in a preselected plane to capture most of the available sunrays throughout a year. Thus, total sunrays falling on a width w of the solar cell 4 throughout a year is maximum. Thus, as per yet another embodiment of the present invention, solar cells 4 and 5 in a panel 1 to be used in the solar energy generation system 100 are moveable in a plane by the strings 9.

[0067] Fig. 6E illustrates part of the panel 1 having the solar cell 4 placed on its ideal position with respect to the reflecting trough 2. The solar cell 4 is placed on the position using strings 9. The strings 9 are connected to roller 13 connected to the sidewalls 6 and 7. As per one of the embodiment of the present invention, the sidewalls are hollow and the roller 13 is placed within the sidewalls 6 and 7. The strings 9 are connected to the roller 13 wherein the roller 13 acts as a pulley. A motor or a similar actuator based systems is connected to the roller 13 that helps in moving the strings 9 so as to cause movement of the solar cell 4. Both the solar cells 4 and 5 of the panel 1 move in tandem. This is further illustrated in Fig. 6F. A panel 1 as per one of the embodiment of the present invention is shown. The panel 1 has two reflecting troughs 2 and 3, and two elongated high efficiency solar cells 4 and 5, where each one of the solar cells are placed on focal line of a reflecting trough using strings 9. The strings 9 are connected to multiple rollers 13 present within sidewalls 6 and 7. As per this embodiment of the present invention, the strings 9 run across the entire length of the panel through the sidewalls 6 and 7 and also the base plate 10. Multiple rollers 13 are placed at each comer of the base plate 10 and the sidewalls 6 and 7, so that the strings 9 are connected to the multiple rollers 13. A motor or an actuator means is also provided within the sidewalls 6 and 7, or the base plate 10 to exert pull or push force on the strings 9. Amount of pull or push force exerted by the motor is generally automated by tracking incident radiation from sun or can be pre-programmed basis historical data. It can also be done using various types of sensors that detect amount of sunrays falling on a solar cell 4 or 5. The strings 9 using the rollers 13 cause movement of the solar cells 4 and 5. As both the solar cells 4 and 5 are connected to each other using strings 9, the movement of the solar cells 4 and 5 are also synchronized. Thus, both the solar cells 4 and 5 are kept at their ideal position to receive reflected sunrays from their respective reflecting troughs 2 and 3 throughout a year. Also, it must be noted that the strings 9 cause movement of not only the solar cells 4 and 5, but also the heat sinks 11 and low efficiency solar cells 12 attached on top of the solar cells 4 and 5. However, it must be readily understood that the strings can move the solar cells 4 and 5 in tandem, either with both the heat sinks 11 and low efficiency solar cells 12, or with only the heat sinks 11. Further, since, all the panels 1 are arranged in same orientation in rows, focus of all the reflecting troughs of the solar energy system 100 will also change in sync. Thus, strings 9 attached to all the panels 1 of the solar energy generation system 100 can be attached to a single motor and can be used to move all the solar cells 4 and 5 in a synchronized manner. Thus, less amount of energy is required in moving the solar cells 4 and 5.

[0068] As per yet another embodiment of the present invention, blower 14 is used to cool the solar cells 4 and 5. Fig. 7A is an illustration of a blower 14 incorporated within the sidewall 6 to blow highly directional cold air 15 on to the solar cell 4 and the heat sink 11. A small slit can be cut on an inner wall of the sidewall 6 so that the blower 14 can be placed within the sidewall 6. The same slit can also be used to attach strings (not shown) holding the solar cell 4, to a roller (not shown) placed inside the sidewall 6. It must be noted that the cold air 15 can be blown directly on the solar cell 4 or on the heat sink 11 placed on top of it, or both. As solar cell 4 gets heated, the heat sink 11 which is generally made up of aluminum fins receives the heat from the solar cell 4. As a result, the heat sink 11 gets heated. When cold air 15 is blown on to the heat sink, the cold air 15 reduces the temperature of the heat sink and dissipates the heat. Thus, the heat developed by solar cell 4 gets transferred to the heat sink 11, where the cold air 15 dissipates the heat. Thus, overall temperature of the solar cell 4 is maintained. Fig. 7A shows only part of the panel 1 having a blower 14 present within the sidewall 6. Similarly, another blower 14 can be present in sidewall 7 that can blow laminar cold air 15 on to the solar cell 5 and its associated heat sink 11. Fig. 7B illustrates a similar example of a panel having two blowers 14 blowing cold air 15 on to two solar cells 4 and 5 and their associated heat sinks 11. The panel 1 as per the present embodiment of the invention comprises of a small gap 16 in between two reflecting troughs 2 and 3. The gap 16 can act as an outlet for the cold air 15 blown in to the panel 1 by the blowers 14. As explained earlier, the cold air 15 can be blown either to the solar cell 4 and 5 directly or on their associated heat sinks 11. The blowers 14 are placed inside sidewalls 6 and 7 that are used to blow cold air 15. As cold air 15 passes through the heat sinks 11 and/or the solar cells 4 and 5, it extracts heat from the heat sinks 11 and/or the solar cells 4 and 5. Thus, the cold air 15 exiting the heat sinks 11 and/or the solar cells 4 and 5 becomes warm air 1501 and 1502 due to the heat. That warm air exits the concentration unit 1 through the gap 16. Thus, over all temperature of the panel 1 is maintained. As per this embodiment of the present invention, the blowers 14 are designed to blow the cold air 15 in such a way that it exits through the gap 16, after passing through the heat sinks 11 and/or the solar cells 4 and 5. As per yet another embodiment of the present invention, a suction unit or an exhaust can be placed within the gap 16 to suck out the warm air 1501 and 1502. [0069] As per yet another embodiment of the present invention, sides of the panels 1 except for the base plate 10, sidewalls 6 and 7, and the top glass 8, are also covered by transparent glass plates 8A. This is shown in Fig. 7C and 7D. An opening 16A exits in the glass plate 8A. The blowers 14 are arranged at different locations in sidewalls 6 and 7 respectively. The blowers 14 blow in highly directional cold air 15, which exits the panels 1 through the opening 16A. The cold air blown are highly directional and the speed and angle at which blowers 14 emit the cold air 15 should be predetermined in such a way that the when the cold air 15 becomes warm air 1501 and 1502, after passing through the heat sinks 11, they can exit the panel 1 through the opening 16A. The warm air 1501 and 1502 leaves the panel 1 and exits the solar energy generation system 100 through spaces available between adjacent panels 1. Fig. 7D illustrates a top view of multiple panels 1 having opening 16A present at two different sides of the panels 1.

[0070] As per yet another embodiment of the present invention, a single blower 14 can be used in a panel 1. Fig. 7E illustrates a panel 1 with a single blower 14 placed within a sidewall 6 blowing cold air 15 on to both the solar cells 4 and 5 and their associated heat sinks 11. As the cold air 15 passes through both the solar cells 4 and 5 and their associated heat sinks 11, it becomes warm air 1503. A small slit 17 is present on the side wall 7 for the warm air 1503 to exit the panel 1. An exhaust fan 18 can also be placed at the position of the slit 17 so that the warm air 1503 can be sucked out of the panel 1. As per this embodiment of the present invention, a thin glass plate 19 is placed within the panel 1, between the solar cells 4 and 5 and the reflecting troughs 2 and 3. The glass plate 19 and the glass top 8 forms a passage for the cold air 15 to enter and exit the panel 1. The glass plate 19 is chosen to be thin enough not to cause any optical deviation to sunrays. The glass plate 19 is also coated with anti-reflective coating to allow all the sunrays hitting on it to pass through. Further, it must be noted that cold air 15 as per this embodiment of the present embodiment should be cold enough so that the cold air 15 passing through the solar cell 4 and its heat sink 11, should still remain cold enough to be able to dissipate the heat generated in the solar cell 5 and its heat sink 11. Also, it must be noted that the position of the blower 14 and the exhaust 18 can be interchanged without affecting the operation of the panel 1, as per yet another embodiment of the present invention.

[0071] Fig. 8A is an illustration of top view of a solar energy generation system 100 having multiple rows of panels 1. Each panel 1 has two solar cells 4 and 5. Each solar cell 4ai or 5ai present in a row is connected serially to its corresponding solar cell 4aii or 5aii present in adjacent column of the same row. Thus, an electrical conductor 20a connects solar cells 4ai...4an in an electrically serial circuit. Similarly, an electrical conductor 21a connects solar cells 5ai....5an in an electrically serial circuit. Similarly, other electrical conductors 20b...20n, and 21b....21n serially connects their corresponding solar cells 4bi...4bn and

5bi .5bn respectively. The number of conductors 20 and 21 are dependent upon the number of panels 1 present in each row and the number of rows present in the solar energy generation system 100. Further, each of the rows of solar cells 4 and 5 of the solar energy generation system 100 are in parallel connection to each other. As per yet another embodiment of the present invention, solar cells 4a are connected in series with other solar cells 4 of the other rows of panels 1. Thus, all the solar cells 4 of the solar energy generation system 100 are connected in series with each other. Similarly, all the solar cells of all the rows of panels 1 of the solar energy generation system 100 are connected in series. As mentioned earlier, each of the high efficiency solar cell 4 and 5 itself comprises of multiple solar cell units 401 that are connected to each other in a serial connection to form each one of the elongated solar cells 4 or 5. This is shown in Fig 8B. As known in all serial circuits, current of the entire solar cell 4 is same as the minimum current generated by one of the solar cell unit 401. Hence, it must be noted that sunrays should fall equally on each one of the solar cell unit 401 throughout a day. This is further, explained in the next embodiment.

[0072] Fig. 9A-9D illustrates various angles at which sunrays hit the solar energy generating system 100 at different times of a day. Fig. 9A depicts a side view solar energy generation 100 having n number of panels lai...lan, as seen from X axis, where panel lai is the east-most panel and the panel lan is the west most panel. At morning, when sunrays fall at an inclined angle, a small part 402ai of the solar cell 4ai of the east most panel lai, does not receive any reflected sunrays. As a result, the amount of current generated by solar cell units 401 present in the part 402ai is very low. Since, all the solar cell units 401 are connected in series to form each of solar cells 4ai to 4an, and all the solar cells 4ai....4an are connected in series, the total current generated by solar cells 4 present in row of panels la will be very low. This will be same for all rows of solar cells 4 and 5 present in all the rows of the solar energy generation system 100. Similarly, during evening as sunrays 101 will fall at an inclination, a part 402an of the solar cell 4an of the west-most panel lan will not receive any reflected sunrays. Thus, overall current generated by solar cells 4a will be very low both during morning and evening. This is same for all rows of solar cells 4 and 5. As shown in Fig. 9A an amount of sunlight 104 at morning and 105 at evening falls outside the panels lai and lan respectively. As per this embodiment of the present invention, a termination unit 22(22ai and 22an) is placed on east of the east most panels li of all the rows, and on west of west-most panels In of all the rows. This is further explained using Fig. 9B. Two termination units 22 are placed at tow ends of a row of panels 1. The termination units 22 are just reflecting troughs that receive incoming sunrays and reflect back. As shown in Fig. 9A terminating unit 22ai placed on east side receives sunrays 104 during morning and reflect that back on to the part 402ai of the solar cell 4ai. Similarly, during evening termination unit 22an placed on west side receives sunrays 105 and reflect that back on to the part 402an of the solar cell 4an. Thus, current generated by arrow of solar cells 4 at morning and evening will also be high. Similarly, termination units 22 are placed on both ends for all the panels 1 of all the rows, increases current generated by solar cells 4 and 5 during morning and evening. Each termination unit 22 comprises of two reflecting troughs that are aligned with the reflecting trough 2 and 3. This is further explained using Fig. 9C. Fig. 9C shows a top view of panels 1 present in a row of the solar energy generating system 100, with two termination units 22a and 22n placed at two ends of a row. The termination units 22ai present on east side, receive morning sunrays 104 that were previously untapped, and reflect that back to two solar cells 4ai and 5ai of the panel lai. Similarly, termination unit 22an present on the west side receives sunrays 105 that was previously untapped and reflect that back onto the solar cells 4an and 5an. Further, any one of the termination unit 22 of a row can also act as an electronics circuit where all the solar cells 4 and 5 of that row are connected serially to each other. All such termination units 22 can then be connected to each other electrically to generate a final output of the solar energy generating system 100.

[0073] The dimension of the termination units 22a and 22n should be so chosen that they can receive sunrays from morning 7 am to evening 5 pm, and redirect them to solar cells 4 and 5. This is further explained using Fig. 9D. Each of the termination unit has a glass top 2208(2208ai and 2208an) and side wall 2206 (2206ai and 2206an). The sidewall 2206ai is designed to be at an angle of 30°. Having a 30° angle allows sunrays 104i at morning 7 am to hit the terminating unit 22ai and reflect back on to the solar cell 4ai. In the figure 9D, the length of 402ai is the length of the solar cell 4ai that receives sunrays reflected from terminating unit 22a at morning 7 am. At 8 am, incidence angle of the sunrays will decrease. Thus, the length of the solar cell 4ai that will receive sunrays reflected from termination unit 22ai will also decrease. Eventually at noon, termination units will not be used to direct the sunrays to solar cells. After which, the termination unit 22an placed on the western side will become effective. The termination unit 22an also has a sidewall 2206an and a glass stop 2206an. The angle between the sidewall 2206an and ground should be around 30°. Having such a design helps in receiving sunrays 105i at 5pm and reflects them back to solar cell 4an. The length 402an that receives reflected sunrays 1051 at 5pm is same as that of the length of 402ai. Thus, 402ai is the maximum length of the solar cell 4ai that receives sunrays from termination unit 22ai at morning 7am. Similarly, the length 402an is the maximum length of the solar cell 4an that receives sunrays from termination unit 22an at 5 pm. The design of the termination units 22 are so chosen that the solar energy generation system 100 can convert sunrays to solar energy from 7am to 5 pm in a day. Intensity of sunrays before 7am and after 5pm is very low and hence, inconsequential to the overall efficiency of the solar energy generating system 100. Also, the length 402ai of the solar cell 4ai and the length 402an of the solar cell 4an is same. As per yet another embodiment of the present invention, the sidewall 2206 of the termination units 22 is also made up of glass.

[0074] As per yet another embodiment of the present invention, the termination unit 22 does not have a sidewall 2206. The top glass 2208 is provided at an inclination to cover the termination unit 22 as shown in Fig. 9E. The top glass 2208 is a transparent glass similar to top glass 8 of the panels 1 and is coated with non-reflecting coatings. Thus, the top glass 2208 of the termination unit 22 allows morning and evening sunrays to enter the troughs of the termination units 22 and get reflected back to solar cells 4 and 5. The length of the termination units 22 can be increased or decreased to increase the time period during which sunrays are converted to solar energy. In the previous embodiment, the length of the termination units 22 are so adjusted that they can capture sunrays from morning 7 am to evening 5 pm. However, to capture sunrays from morning 8 am to evening 4 am, the length of the termination units 22 will be lesser.

[0075] Fig. 10A-10B illustrate yet another embodiment of the current invention, where terminating units 22 acts as electrical termination for solar cells 4 and 5 of a row. As described in previous embodiments, solar cells 4 of row are connected to each other serially via electrical connector 20a. The electrical connector 20a terminates at the termination unit 22an. At the termination unit 22a, there is a special electrical connector 27a, which is fixed to the termination unit 22an at one end and flexible at the other end. The special electrical connector 27a is fixed to a sidewall 2207 of the termination unit 22. The flexible end is connected to the electrical connector 20a that is connecting all the solar cells 4 of the row. The flexible part is essential as solar cells 4 move and thus, point of contact between the electrical connector 20a and the electrical connector 27a will change basis position of the solar cells 4. Fig. 10B shows a top view of a termination unit 22an having two electrical connectors 27ai and 27aii. Both the electrical connector 27ai and 27aii are identical in nature and are connected to electrical connector 20a and 21a, for two different rows of solar cells 4 and 5. The electrical connector 27ai and 27aii are generally very thin and hence, cast a very negligible shadow on the underlying troughs. Also, it must be noted that the termination unit 22 either on the east side or on the west side can be used for creating electrical termination of solar cells 4 and 5 in a row of panels 1. The terminating units 22ai or 22an can then be connected to each other to form the final electrical circuit of the solar cells 4 and 5.

[0076] As per yet another embodiment of the present invention, the electrical connector 27ai and 27aii are fixed with the top glass 2208 that is at an inclination with the termination unit 22a. [0077] Fig. 11A-11B illustrates parts of two adjacent panels lai and laii of the solar energy generating system 100. As shown in Fig. 10A, a small amount of sunrays 106 that fall near edges of the two glass tops 8ai and 8aii, bends because of refraction. Thus, the sunrays 106 get wasted as it does not get converted to solar energy. Fig. 10B illustrates another embodiment of the present invention, where a transparent unit 23 is placed between two glass tops 8. The transparent unit 23 is made up of gel like substance or transparent plastics that have the same refractive index as that of the glass top 8. Thus, the sunrays 106 hitting at edges of two adjacent glass tops 8 will pass through without any deviation. Thus, those sunrays 106 will also be converted into solar energy.

[0078] Figs. 12A-12E illustrates yet another embodiment of the present invention where small trough units 28 are present between adjacent panels 1 in a row. Fig. 12A illustrates a side view of a row of panels 1 of the solar energy generating system 100. As shown in the Fig. 12A, small gaps exist between two adjacent panels 1 of a row. The gaps are generally around 6mm wide. When sunrays 107 that hit the gaps, they are not reflected back to any solar cell 4 or 5. Thus, a portion or at least a single solar cell unit 401 of solar cell 4 does not receive any sunlight. And as mentioned earlier, each solar cell 4 is an array of serially connected solar cell units 401 and when one single solar cell unit 401 does not receive sunlight, the efficiency of the entire row of solar cell 4 becomes zero. To counter the gaps, small trough units 28 can be placed in between two adjacent panels 1. Each trough unit 28 is a trough that is aligned with the reflecting trough 2 or 3, with a length of 6 mm. Trough units have the same semi-circular curved mirror surface as that the reflecting troughs 2 and 3. The trough units 28 can receive the sunrays 107 and can direct them on to solar cells 4. The figure 12B shows trough units 28 receiving the sunrays 107 that were previously unutilized and reflecting them back to solar cells 4. As a result, almost all the solar cell units 401 receive sunrays and thus, the overall efficiency of the row of the solar cells 4 increase. Each trough unit 28 have similar curvature as reflecting troughs 2 and 3 and are placed in the same way as the reflecting troughs 2 and 3. A perspective view of trough units 28 placed between two adjacent panels 1 having concentrating troughs 2 and 3 is illustrated in Fig. 12C. It must be noted here, that Fig. 12C only shows parts of the concentrating troughs 2 and 3, of the panels 1 of the same row. Two panels lai and laii of a row have four concentrating troughs 2ai, 3ai, 2aii and 3aii. Two trough units 28 are placed in between concentrating troughs 2ai and 2aii, and 3ai and 3aii. The trough units 28 have similar curvature and height as that of the concentrating troughs 2 and 3, and a length of 6mm. Thus the trough units 28 eliminate the gap in reflecting surface between two panels 1 of the same row.

[0079] Further, as explained earlier, using termination units 22, the solar energy generating system 100 can convert sunrays to solar energy from morning 7am to evening 5pm. Thus, a trough unit 28 receives sunrays throughout a day and reflects that back to two different solar cells 4 of two adjacent panels 1 of the same row. This is explained using Fig. 12D. At morning 7 am, trough unit 28 present between panel lai and laii, receives sunrays 108 and sends them as 108r to solar cell 4aii. At 9 am, trough unit receives sunrays 109 at a different angle and reflect sunrays 109_r to solar cell 4aii. Similarly, again at 3pm, trough unit 28 receives sunrays 110 and reflect back sunrays 110_r to solar cell 4ai. Finally at 5pm, trough unit 28 receives sunrays 111 and reflect back sunrays lll_r to solar cell 4ai. It must be noted that the location in which reflected sunrays from trough unit 28 hit the solar cells 4 changes. At morning 7am, the reflected sunrays 108_r hit 4aii at position 4aii_r. Similarly, at evening 5pm, the reflected sunrays 11 l_r hit solar cell 4ai at 4ai_r. It must be noted that length of the solar cell 4ai between edge and 4ai_r is same as the length of the solar cell 4ai between an opposite edge and position 4aii_r. It is illustrated as 4a_r in the Fig. 12D. This is same for all the solar cells 4 and 5 present in all the rows. Hence, in the solar cells 4, two portions of 4a_r will receive sunrays from trough units 28 throughout a day. These two portions of 4ar will be present at opposite ends of the solar cell 4.

[0080] As previously mentioned, solar cell units 401 that are present between the portions 4a_r will receive sunlight from trough units 28. In Fig. 12E, the solar cell units 401 that are present between the portions 4a_r are depicted as 401a_r. Even though the trough units 28 reflect back sunlight to solar cells 4, the intensity of sunlight falling on the troughs 28 are very less as the sunlight has to go through various the glass top 8, edges of panels 1. Thus, even though the trough units 28 are provided between the gaps, they are not properly optimized to receive the same intensity of sunlight as reflecting troughs 2 or 3. Thus, the intensity of reflected sunrays by the trough units 28 are also less. This cause solar cell unit 401a_r to receive less intensity of sunlight from rest of the solar cell units 401 of the solar cell 4. Further, in case the trough units 28 are not present in the gap between adjacent panels, the sunlight falling in to the gap will not be reflected back to any solar cell unit 401. Even the sunlight that will fall on the edge of the concentrating trough 2 will not be completely reflected back to any solar cell unit 401. Further, there will be disruption of sunlight and reflected sunlight at the edges between two panels 1. Even with the transparent unit 23 placed between glass tops 8 of adjacent panels, a part of the sunlight at the edges of panels 1 will get disrupted. For all those reasons, the intensity of sunlight received by solar cell units 401a_r will be less. Thus, the amount of solar energy generated by the solar cell units 401a_r is also less. And, since all solar cell units 401 are connected in series, the total solar energy generated by a row of solar cell 4 also becomes less. To get optimum amount of solar energy, all the solar cell 401 of the solar cell 4 needs to generate same amount of solar energy. If any solar cell unit 401 generates more solar energy, that extra solar energy will get wasted. Thus, solar cell units 401a_r produce less solar energy because of disrupted sunlight and lower the solar energy generated by the whole solar cell 4. Therefore, sizes of the solar cell unit 401a_r are increased slightly to negate the above mentioned disruptions. The increase of the size is such that even when there is disruption of light, the amount of solar energy generated by the solar cell units 401a_r is same as the other solar cell unit 401 that are not increased in size. Fig. 12E shows a solar cell 4 with solar cell units 401_r that have increased size compared to other solar cell units 401. The solar cell units 401_r are generally made 5% larger compared to other solar cell units 401. This is same for all the solar cells 4 and 5 of the solar energy generation unit 100. This makes the whole system more efficient. Further, it must be noted, that the length of 4a_r is same as the portion 402ai and 402an, used to capture reflected sunrays from termination units 22, described in one of the previous embodiment.

[0081] Figs. 13A-13B illustrates a method of manufacturing a panel 1. Fig. 13A shows a perspective view of structure of a panel 1. As described earlier, the sidewalls 6 and 7, and the base plate 10 forms the structure of a panel 1. The structure further has a thin support 24 lying on its middle that acts as a separation for the reflecting troughs 2 and 3 to be placed inside the structure. The structure further has multiple clips 25. The clips 25 are attached on edges of the sidewalls 6 and 7, the bottom plate 10 and the support 25. The size of the clips 25 are arranged in such a way that when a sheet of reflecting material 26 is inserted through the clips 25 and the structure, the sheet of reflecting material 26 forms a parabolic shape. In Fig. 11A, the sheet of reflecting material 26 is inserted inside the structure in such a way that it passes through all the clips 25 placed on sidewall 6, parts of bottom plate 10 and on one side of the support 24. Thus, the sheet of reflecting material 26 forms a parabolic reflecting mirror which acts as a reflecting trough 2. Fig. 13B shows a side view of the structure with the clips 25. Similarly, when another sheet of reflecting material is inserted in such a way that the sheet passes through clips 25 on sidewall 7, parts of bottom plate 10 and on other side of the support 24, it forms the reflecting trough 3. The height of the clips 25 are specially designed so that top of the clips 25 forms a parabolic shape. Thus, the clips 25 are used to hold the sheet of reflecting materials 26 in a parabolic shape. The support 24 acts a separation between two reflecting troughs 2 and 3.

[0082] Fig. 13C illustrates a preferred embodiment of manufacturing the reflecting troughs 2 and 3 of the present invention. The structure of the panel consists of plates 29. The plates are designed in the complex semi-circular shape just like the desired shape of the reflecting trough 2 and 3. A support 24 is present that to separate out the two reflecting troughs 2 and 3. The plates 29 are placed in such a way that when a sheet 26 of plastic with reflecting surface is pushed through the structure, the plates 29 bends the sheet 26 to form the reflecting troughs 2 or 3. A set of clips 30 can be present one on the sidewalls 6 and one on the support 24 to hold the sheet 26 at its position in the shape of concentrating troughs 2 and 3.

[0083] As per yet another embodiment of the present invention, multiple solar units 401 of a solar cell 4 are connected in series via solder and solder mask. Fig. 14A illustrates a solar cell 4 having multiple solar cell units 401. On solar cell units 401 at one end solder 31 is present and at opposite end mask 32 is present. For the next solar cell unit 401, the position of the solder 31 and mask 32 are interchanged. Thus, a series of solder 31 and mask 32 is created on one edge of the solar cell 4 and another series of mask 32 and solder 31 are created on opposite edge of the solar cell 4. On the side of the heat sink 11 connected on top of the solar cell 4 multiple copper connectors 33 are present as shown in Fig. 14B. Each of the copper connectors 33 are connected to either the solder 31 or the mask 32 of the solar cell 4. Thus, the solder 31, mask 32 and the copper connectors 33 creates an array of serially connected solar cell units 401. Thus the flow of current is maintained from positive terminal to negative terminal of adjacent solar cell units 401. The flow of current is depicted by arrows in Fig. 14C.

[0084] As per yet another embodiment of the present invention, the heat sink 11 can be used to connect the solar cell units 401 of the solar cell 4. Fig. 14D illustrates a heat sink 11 designed to act as connector between two adjacent solar cell units 401 of a solar cell 4. The heat sink 11 as per this embodiment of the present invention has multiple insulators 34 placed in between aluminum fins 11c and the bottom plate lib. Thus, the insulators 34 divide the heat sink 11 into smaller parts. Each part of the heat sink 11 is designed to act as connector between two adjacent solar cell units 401. Thus, an array of serially connected solar cell units 401 is created, which act as the solar cell 4.

[0085] As per yet another embodiment of the present invention a sliding sheet 35 is provided to guide cold air 15 from blowers 14 to solar cells 4 and 5. In Fig. 15A -15B parts of the solar panel 1 implementing the siding sheet 35 is shown. Please note that only parts of the solar panel 1 are shown for easy understanding purposes only and should not be considered as a limitation. A sheet of transparent plastic 35 is attached to the side of the solar cell 4 at one end and at other end is supported by rolling mechanisms 36. The sheet 35 can also be made out of flexi glass. The sheet 35 is placed in such a way that it lies beneath the blower 14 blowing cold air 15 on to the heat sink 11 attached on top of the solar cell 4. The sheet 35 is flexible and it acts as a guiding mechanism for directing the cold air 15 on to the heat sinks 11. Being attached to the heat sink 4, when the heat sink 4 moves, the sheet 35 being flexible is directed to bend inwards using the rolling mechanisms 36. As shown in Fig. 15B, when the solar cell 4 moves to the left, the sheet 35 moves through the rolling mechanism and bends and remains close to the side wall 6. The rolling mechanism 36 is such arranged that the sheet 35 remains as close to the sidewall 6 as possible. The length of the sheet 35 is also preselected such that when the solar cell 4 at its extreme left and right positions, the sheet 35 neither moves out of the sliding mechanism 36 nor come in contact with the underlying reflecting trough 2. The sheet 35 being transparent allows sunrays to pass through. Thus, the sheet 35 can act as a guide for the cold air 35 to hit the heat sink 11. Also, the sliding sheet 35 is kept inside the panel 1 as to bring the sheet outside through the sidewall 6 will require a slit to be cut across the entire length of the sidewall 6. This will cause structural integrity problem with the panel 1. Hence, the sheet 35 is bended and kept inside the panel 1. However, even though the sheet 35 and the rolling mechanisms 36 will obstruct a part of the summer sunrays to hit the reflecting trough 2, the amount of summer sunrays obstructed will be negligible.

[0086] As per yet another embodiment of the present invention, the sheet 35 gets rolled up around a part of the rolling mechanisms 36. This is illustrated in Fig. 15C. Such a rolling can be done using known in the art shutter rolling systems. As per this embodiment of the present invention, the sheet 35 will roll out and roll in based on the position of the solar cell 4 and create a guide for the cold air 15.

[0087] As per yet another embodiment of the present invention, the sidewalls 6 and 7 are kept at an angle less than 23.5°, as mentioned in the primary embodiment of the present invention. Fig 16A-16B illustrates the advantages of having solar panels 1 with sidewalls 6 at angles less than 23.5°. Fig. 16A shows parts of the solar panel 1 as per the primary embodiment of the present invention with sidewall 6 at an angle of 23.5° + 90° with respect to the base plate 10. This allows summer sunrays 101a to enter the panel 1 and hit the reflecting trough 2. However, the most of the summer sunrays 101a that enter the panel 1 because of the extra angle 23.5°, are not reflected back to the solar cell 4. Experiments show that only 10-20% of the summer sunrays 101b that enter the panel because of the extra angle of 23.5° are reflected back to the solar cell 4. Hence, the angle of the sidewall 6 with respect to the base plate 10 of the panel 1 can be reduced. Fig. 16B shows a panel 1 with this embodiment of the present invention, where angle between the sidewalls 6 and 7 with respect to the base pate 10 is less. As shown in the Fig 16B, a part of the summer sunrays 101a gets obstructed by the new angle of the sidewalls 6. The angle at which the sidewalls 6 is at form the base plate 10 is now 90° + 15°. This angle helps in capturing part of the summer sunrays 101b that are reflected back to the solar cell 4 and also reduces overall size of the panel 1. Similarly, the angle of the sidewall 7 can also be made less to capture part of the winter sunrays that can actually be converted to solar energy. As per yet another embodiment of the present invention, the angle of the sidewalls 6 and 7 can be reduced to 90°+7°.
