The specific structure of the portable double-sided solar panel according to the embodiment of the present invention will be described with reference to fig. 1 to 6.
The invention discloses a portable double-sided solar panel, as shown in fig. 1, fig. 3 and fig. 5, the portable double-sided solar panel of the embodiment of the invention comprises a photovoltaic panel 1 and a light reflection accessory, the photovoltaic panel 1 comprises a substrate 11, a support 12 and double-sided solar cells 13, the support 12 is rotatably arranged on the substrate 11, the double-sided solar cells 13 are arranged on the substrate 11, the light reflection accessory is of a foldable structure and comprises a tiled area 21 and a supporting area 22 which are connected, the tiled area 21 is used for placing the photovoltaic panel 1, the tiled area 21 is used for reflecting sunlight to a front light receiving surface and a back light receiving surface of the double-sided solar cells 13, the supporting area 22 is arranged at intervals with the photovoltaic panel 1, and the supporting area 22 is used for reflecting the sunlight to the front light receiving surface and/or the back light receiving surface. It can be understood that, in the actual use process, firstly the reflection fitting is spread on the ground, then the support area 22 is folded by utilizing the foldability of the reflection fitting, and then the photovoltaic panel 1 is placed on the tiling area 21, in the working process, on one hand, due to the existence of the tiling area 21, light rays which cannot be directly irradiated to the front light receiving surface can be transmitted towards the photovoltaic panel 1 under the reflection action of the tiling area 21, so that the light intensity received by the front light receiving surface is improved, and the power generation amount of the photovoltaic panel 1 is improved. On the other hand, due to the existence of the support region 22, the light which cannot be directly irradiated to the front light receiving surface or the back light receiving surface can be transmitted towards the photovoltaic panel 1 under the reflection action of the support region 22, so that the light intensity received by the front light receiving surface or the back light receiving surface is improved, and the power generation amount of the photovoltaic panel 1 is improved. In addition, because the reflection of light accessory is beta structure, it is all very convenient in transportation and storage process, and the reflection of light accessory can select for use the reflecting plate that the quality is lighter, has promoted portable two-sided solar panel's portability. That is to say, after a light reflection fitting with small mass and relatively low cost is added, the light intensity received by the front light receiving surface and the back light receiving surface of the photovoltaic panel 1 can be greatly improved, and the power generation amount and the power generation efficiency of the portable double-sided solar panel are improved.
It should be noted that, in the embodiment of the present invention, the distribution position of the support region 22 may be various, and in some embodiments, as shown in fig. 1, the support region 22 is located on the back-light receiving surface side of the photovoltaic panel 1; in some embodiments, as shown in fig. 3, the support region 22 is located on one side of the front light receiving surface of the photovoltaic panel 1; in some embodiments, as shown in fig. 5, two support regions 22 are provided and are located on two sides of the photovoltaic panel 1.
Optionally, the double-sided solar cell 13 is mainly made of a crystalline silicon cell, and includes any one of seven double-sided cells, i.e., an N-type PERT double-sided cell, a P-type PERT double-sided cell, an HJT double-sided cell, an HIT double-sided cell, an N-type passivated contact cell, a P-type passivated contact cell, and an IBC double-sided cell, so that the double-sided solar cell 13 has the advantages of reduced light attenuation, good weak light effect, low temperature coefficient, and the like. Of course, in other embodiments of the present invention, the type of the bifacial solar cell sheet 13 can also be selected according to actual needs.
Preferably, there are two support areas 22, the two support areas 22 are respectively connected to two ends of the tiling area 21, and the photovoltaic panel 1 is located between the two support areas 22. Therefore, the support regions 22 can reflect light to the front light receiving surface and the back light receiving surface of the photovoltaic panel 1, and simultaneously improve the light intensity received by the front light receiving surface and the back light receiving surface, thereby further improving the power generation efficiency and the power generation amount of the photovoltaic panel 1. Optionally, the light reflecting fitting is a reflective film, a foldable reflective plate, or other type of light reflecting structure with folding characteristics, and in the embodiment of the present invention, the specific type of the light reflecting fitting may be selected according to actual needs.
In some embodiments, as shown in fig. 2, 4 and 6, the supporting region 22 includes a first inclined region 221 and a second inclined region 222, one end of the first inclined region 221 is connected to the tiled region 21, the second inclined region 222 is connected to the other end of the first inclined region 221, and the first inclined region 221, the second inclined region 222 and a portion of the tiled region 21 form a triangular prism. It can be understood that the first inclined area 221, the second inclined area 222 and a portion of the tiled area 21 are enclosed to form a triangular prism, so that the stability of the supporting area 22 can be ensured, and the phenomenon that the supporting area 22 collapses due to the foldability of the light reflecting fitting during the actual use process can be avoided, thereby ensuring the user satisfaction of the portable double-sided solar panel.
In some specific embodiments, the first sloped region 221 is angled from 20 ° to 70 ° relative to the tiled region 21. It can be understood that the included angle between the first inclined area 221 and the flat pavement area 21 can be adjusted according to actual needs, and especially can be adjusted according to the position of the sun and the reflective fittings, so that the photovoltaic panel 1 can absorb sunlight to the maximum extent, and the power generation efficiency and the power generation amount of the photovoltaic panel 1 are improved.

In some embodiments, as shown in fig. 1, the second inclined region 222 is disposed parallel to the substrate 11. It can be understood that the second inclined region 222 is arranged parallel to the substrate 11, so that light reflected by the second inclined region 222 can be better received by the back-to-light receiving surface, thereby improving the power generation efficiency and the power generation amount of the photovoltaic panel 1.

It can be understood that, in an actual working process, an excessively high intersection line of the first inclined region 221 and the second inclined region 222 may result in a low area utilization rate of the reflector, that is, a part of light reflected by the reflector cannot be received by the photovoltaic panel 1, and an excessively low intersection line of the first inclined region 221 and the second inclined region 222 may result in a small amount of reflected light, which is not favorable for increasing the power generation amount of the photovoltaic panel 1. In this embodiment, the intersection line of the first inclined area 221 and the second inclined area 222 is flush with the upper edge of the photovoltaic panel 1, which is obliquely arranged, so that the area utilization rate of the light reflecting fitting can be ensured, the manufacturing cost can be controlled, and more light rays can be ensured to be reflected, thereby increasing the power generation amount of the photovoltaic panel 1. Of course, it should be additionally noted herein that, in the present embodiment, the position relationship between the intersection line of the first inclined region 221 and the second inclined region 222 and the upper edge of the photovoltaic panel 1 that is obliquely disposed may also be adjusted according to actual needs, and is not limited to the level of the present embodiment.
In some embodiments, the width of the substrate 11 is H1, the distance from the intersection of the front light receiving surface and the tile 21 to the edge of the tile 21 is H2, and H2 is greater than 0 and less than or equal to H1. It can be understood that the distance from the intersection line of the front light receiving surface and the tiled area 21 to the edge line of the tiled area 21 is too large, which results in a low area utilization rate of the light reflecting fitting, that is, a part of the light reflected by the light reflecting fitting cannot be received by the photovoltaic panel 1, thereby increasing the useless cost of the light reflecting fitting. In the embodiment, the distance from the intersection line of the front light receiving surface and the tiled area 21 to the side line of the tiled area 21 is controlled to be smaller than the width of the substrate 11, so that the area utilization rate of the light reflecting fitting can be ensured, the manufacturing cost can be controlled, more light rays can be ensured to be reflected, and the power generation amount of the photovoltaic panel 1 can be increased.
In some embodiments, the substrate 11 includes a plurality of plate bodies 111 and a plurality of flexible structures 112, each flexible structure 112 being connected between two adjacent plate bodies 111. Therefore, after the base plate 11 is folded, only one plate body 111 is arranged, and the base plate is convenient to store. In the present embodiment, the flexible structure 112 may be made of any material according to actual needs, and the specific structure of the flexible structure 112 is not limited herein.

The invention also discloses a portable photovoltaic power generation system which comprises the portable double-sided solar panel and the portable energy storage power supply 3, wherein the portable energy storage power supply 3 is electrically connected with the photovoltaic panel 1.
Optionally, the portable energy storage power source 3 is connected to the photovoltaic panel 1 through a cable 4, the cable 4 includes one or more conductors insulated from each other and an outer insulating protective layer, and the direct current is transmitted from one place to the photovoltaic panel 1 at another place, so that the charging of the portable energy storage power source 3 by the photovoltaic panel 1 can be ensured.
