Abstract
The utility model relates to a split-type photovoltaic assembly, comprising a photovoltaic assembly body composed of battery pieces. Two bus bars, which are parallel to each other, are arranged in the middle of the front surface of the photovoltaic assembly body. The bus bars divide the photovoltaic assembly body into two symmetrical battery modules in a left-right manner. The battery pieces of the battery module at the left side is connected with the bus bar at the left side, while the battery pieces of the battery module at the right side is connected with the bus bar at the right side. The two parallel bus bars are connected with a first junction box arranged on the back surface of the photovoltaic assembly body. An output terminal of the first junction box is connected in series with a second junction box and a third junction box. The split-type photovoltaic assembly does not generate temperature superposition when large-area hot spots occur, and is capable of guaranteeing that more battery pieces can supply power to a system when the battery pieces in circuits of the photovoltaic assembly become poor in performance or have the hot spots. Therefore, the reliability of the photovoltaic assembly is increased.

Embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
Fig. 1, a kind of split type photovoltaic module shown in Figure 2, has the photovoltaic module of being formed by battery sheet 1, be provided with two busbars that are parallel to each other 2 in the middle of the described photovoltaic module front, the battery modules of two symmetries about busbar 2 is divided into described photovoltaic module, the battery sheet 1 of described left side battery modules is connected with the busbar 2 in left side, the battery sheet 1 of right side battery modules is connected with the busbar 2 on right side, described two parallel busbars 2 are connected with first terminal box 3 that is arranged on the photovoltaic module back side, are serially connected with second terminal box 4 and the 3rd terminal box 5 on first terminal box, 3 outputs; As shown in Figure 3 and Figure 4, described first terminal box 3, second terminal box 4 are identical with the 3rd terminal box 5 structures, by box body 6 and the lid 7 that is arranged on the box body 6, be provided with dividing plate 9 in the middle of described box body 6 inner chambers, dividing plate 9 is divided into two independently cavitys with box body 6 inner chambers, be provided with one in described each cavity for the connection copper sheet 11 that connects battery pack, connect copper sheet 11 and be provided with diode 10, the end is provided with external output line 8.
Particularly, two parts about busbar 2 is divided into photovoltaic module, and the two-part battery sheet 1 in the left and right sides can form same loop by 3 series connection of first terminal box, this photovoltaic module is the same with the assembly of conventional same piece number during operate as normal, when the bad or battery hot spot of battery performance is arranged in the photovoltaic module circuit, bypass diode in first terminal box 3 in the photovoltaic module, second terminal box 4 and the 3rd terminal box 5 will forward conduction, the battery strings short circuit that the diode of conducting is will be with it in parallel; And this photovoltaic module is compared with conventional photovoltaic module, the decreased number of the battery sheet 1 in parallel with diode half, have more battery sheet 1 when the bad or battery hot spot of battery performance is arranged and power to system in the photovoltaic module circuit.
When the photovoltaic module hot spot, hot spot battery sheet will bear reverse voltage still less, and the power that consumes at hot spot battery sheet will be more few, and 1 heating of battery sheet also can be more few, and the reliability of photovoltaic module can improve.
This photovoltaic module reduces half with the battery sheet 1 of each bypass diode 10 parallel connection, when the photovoltaic module operate as normal, the open circuit voltage that the battery sheet 1 in parallel with diode 10 produces reduces half, the reverse leakage current of diode 10 will reduce, this situation had both reduced the electric current of diode 10 consumable components, had improved the stability of diode 10 again.
This split type photovoltaic module can not produce temperature stack when hot spot appears in large tracts of land, and has more battery sheet can guarantee to have in the photovoltaic module circuit the bad or battery hot spot of battery performance the time and power to system, improves the reliability of photovoltaic module.
