Abstract
The utility model relates to a solar power generator for resolving the electric power attenuation caused by battery sheet faults. The utility model discloses a crystalline silicon solar battery module composed of a frame, a monomer solar power series battery, a connection box and by-pass diodes. The utility model is characterized in that a lead-out wire tap is additionally arranged between each column and the adjacent column of the monomer solar power series battery on the frame, the by-pass diodes which has the same quantity of lead-out wire taps additionally arranged are additionally arranged in the connection box, the lead-out wire taps are connected with nodal points in the by-pass diode series group via terminal connectors, when the essential resistance of some faulty battery sheet in the component increases, the electric power exerted on the faulty battery sheet is limited by the by-pass diode in parallel connection with the column of the battery sheet, thereby protecting the component to be used safely and ensuring the power output of the component.
Description
Technical field
The utility model relates to device of solar generating.
Background technology
Known crystalline silicon solar cell modules is made up of a bypass diode in the single solar cell series connection group on framework, the framework, terminal box, the terminal box.This diode is connected to the single solar cell series connection and organizes between the positive and negative lead-in wire, when assembly moves in the solar cell array mode, if there is a cell sheet fault of damaging or being shaded to occur in the square formation in some assemblies, cause this assembly internal resistance to be increased, at this moment the effect of bypass diode is electric current that other assembly is produced this assembly of no longer flowing through, to limit the intensity of hot spot effect on this component faults battery sheet, the unlikely too much unnecessary consumption of electrical power that square formation is produced.More serious hot spot effect still can take place in the fail battery sheet but the electric current that all fault-free battery sheets of this component internal produce is still flowed through, so that electrical piano power loss, assembly damages.
Summary of the invention
For solving the power loss that crystalline silicon solar cell modules brings because of battery sheet fault, the purpose of this utility model provides a kind of crystalline silicon solar cell modules, and it can reduce the electrical power unnecessary consumption of assembly effectively.
The utility model is to realize by following technical scheme, it is made up of framework, single solar cell series connection group, terminal box, bypass diode, its structural feature is to set up a lead-out wire tap between every row of the single solar cell series connection group on the framework and the adjacent column, in terminal box, have additional a plurality of bypass diodes, each bypass diode series aiding connection becomes a series connection group, and the lead-out wire tap is connected with node in the bypass diode series connection group by binding post.
Above-mentionedly have additional a plurality of bypass diodes in terminal box, its quantity of setting up is identical with the quantity that the lead-out wire tap is set up.
The utility model is by adopting the design of lead-out wire tap and bypass diode in parallel, for each the row battery sheet in the assembly provides a bypass diode, make the fail battery sheet can consumable power limitations within the electrical power that each row battery sheet is produced, thereby reduced the electric power consumption of assembly, the assurance assembly is safe and reliable, and still can continue does not provide electric energy to external circuit with continuing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment below with reference to accompanying drawing is further described the utility model.
Among Fig. 1, single solar cell series connection group 2 is arranged on the framework 1, series aiding connection bypass diode 4 is arranged in the terminal box 3, the series connection group two ends of diode 4 are connected with the two ends lead-in wire of single solar cell series connection group 2 by binding post 6, the lead-out wire tap 5 of per two row batteries is connected with node in the bypass diode series connection group by binding post 6 in the single solar cell series connection group, and the body solar cell of whenever itemizing all is in parallel with a bypass diode.When certain cell sheet in a certain row of battery component breaks down and internal resistance when increasing; then be connected in parallel on the bypass diode of these row; can make the electrical power that is applied on the fail battery sheet only limit to the electrical power that this row battery is produced, thereby protect the safety of assembly, guarantee the power output of assembly.
