Abstract
The utility model relates to a solar cell assembly, comprising: an assembly frame in which a cell plate is arranged. The utility model is characterized in that each four cell plates, six cell plates or eight cell plates are connected in parallel with a diode. The utility model has the advantages that as each four cell plates, six cell plates or eight cell plates are connected in parallel with the bypass diode, the heat degree of the cell plates is greatly decreased and the occurrence of serious heat mark is avoided; the diode is connected with each four cell plates, six cell plates or eight cell plates in parallel, and other cell plates work normally, thereby increasing the generating efficiency of the assembly; as an integrated Schottky diode is used, in the practical operation, the operation is greatly simplified; the utility model has better practicability when compared to the operation of welding a bypass diode on each cell plate; besides, the middle part of the welding belt for welding the diode is processed in terms of insulation; and the array way is novel.
Description
Technical field
The utility model relates to a kind of solar module, is used for solar energy converting is become electric energy, belongs to the photovoltaic module technical field.
Background technology
Present assembly is by cover plate, EVA, and the backboard encapsulation is formed, usually constitute by 36 or 72 series connection, assembly in use can have shade under a lot of situations on assembly, the blocking of building, blocking of trees, surface the blocking of dirt, this moment, the battery of shaded side will be by other have the energy that solar module produced of illumination as load consumption, and its power conversion is a heat, light the jaundice that causes EVA, severe patient causes the short term failure of solar cell
In order to solve this influence, assembly junction box is inner can install bypass diode, general 24 or 18 are used a bypass diode, this kind situation can not be avoided hot spot effect fully, when hot spot effect takes place, reverse biased provides by 23 or 17, reverse biased is big, the heat that produces is big, if surpass the withstand voltage limit of battery sheet, then can cause the battery sheet to puncture, also can damage be arranged the battery sheet even without surpassing the withstand voltage limit, the someone propose every welding bypass diode in practical operation also and be not easy to realize.
Summary of the invention
The purpose of this utility model provides a kind of minimizing heat and produces, and can improve the solar module of the conversion efficiency of battery component simultaneously.
In order to achieve the above object, the technical solution of the utility model has provided a kind of solar module, comprises module frame, is provided with the battery sheet in module frame, it is characterized in that, per 4,6 or 8 battery sheet diodes in parallel.
Described diode is with at least two integrated sheet type Schottky diodes that diode integrates.
The utility model compared with prior art has following advantage
1) because the utility model makes per 4,6 or 8 battery sheet bypass diodes in parallel, when wherein a slice is blocked, all the other battery sheet voltages are less than 3V, be to cause the sheet that is blocked to cause damage, therefore significantly reduce battery sheet the degree of heat, and avoided the generation of serious hot spot, and 4,6 of diode bypasses or 8 battery sheets, but all the other battery sheet operate as normal, the generating efficiency of increase assembly;
2) adopt the integrated schottky diode form, in practical operation, simplify the operation greatly, have practicality, weld the welding of diode simultaneously and do the processing of insulation coating at mid portion than every battery sheet welding bypass diode;
3) arrangement mode novelty.
Description of drawings

Fig. 2 is the schematic diagram that is electrically connected of Fig. 1;
Fig. 3 is the concrete connection diagram of diode.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the structural representation of a kind of solar module that provides for the utility model comprises module frame 1, is provided with battery sheet 2 in module frame 1, per 6 battery sheets, 2 diodes 3 in parallel.Diode 3 is the integrated sheet type Schottky diode that two diodes integrate, and is positioned at the blank space of assembly.
As shown in Figure 2, battery sheet 2 with the parallel way of diode 3 is: count from top to bottom, first row's three battery sheets 2 in the left side and second diode of arranging in three battery sheets, the 2 integrated sheet type Schottky diodes 3 in parallel of the left side, another diode in this integrated sheet type Schottky diode 3 is connected in parallel on three battery sheets of first three battery sheets 2 in row the right and second row the right, and next coming in order are analogized.
As shown in Figure 3, concrete connection diagram for diode 3, insulation welding 5 is at mid portion does the welding that insulation is handled, one end of this insulation welding 5 is welded on the pin of diode 3, the other end is welded on the welding 4 at battery sheet 2 back sides, and long welding 5 need be welded on down on the welding 4 of a slice battery sheet 2 every crossing a slice battery sheet 2.
