Description
Technical field
The utility model relates to and a kind of solar energy converting is become the device of electric energy, is specifically related to a kind of solar module.
Background technology
Solar cell is a kind of semiconductor device (or claim physical battery), and it can be directly is electric energy with the transform light energy of sunlight.Owing to need not water, oil, vapour, fuel during its work, only need the characteristics that luminous energy just can generate electricity, can be rated as cleaning in the present age, non-pollution of renewable energy, and installation and maintenance are simple, and long service life can realize unattended operation, extremely people's favor is the outstanding person in the new forms of energy.In the last few years, solar energy be applied in the whole world more and more widely, the communications field particularly, solar power supply system just progressively replaces some traditional power-supply devices, obtains more and more general application.
Solar module is made of a plurality of solar battery sheets, and usually, the battery sheet is arranged in 10 row, 6 array structures, panel and base plate adopt high light transmittance ratio glass, be installed in the framework, be connected in series through welding between the adjacent cell sheet, the welding of drawing at two ends is connected in the terminal box.In use because the projection of flying bird, leaf etc. can produce shade in solar cell surface, at this moment, not only corresponding battery sheet can not send electric energy, can transfer resistance on the contrary to, consume electric energy and heating in the loop, Here it is so-called hot spot effect.Hot spot effect can cause the decline of loop generating efficiency, and then causes the damage of battery sheet.For addressing this problem, the Schottky diode of common bypass in parallel in the series circuit of battery sheet, in the prior art, conventional connected mode is, 3 bypass diodes are set in a terminal box,, draw two targets to terminal box from an end of battery component next-door neighbour terminal box, therebetween and and the battery at two ends draw between the welding, connect described bypass diode respectively.Like this, under the hot spot situation, the bypass diode conducting is with a string (20) battery sheet short circuit, to reduce its influence to solar module.This structure can avoid the battery sheet under the hot spot situation to damage, but its stability under the hot spot situation is general, particularly when adopting that the metalluragical silicon chip is as solar battery sheet cheaply, its hot spot stability is poorer, has limited the application of metalluragical silicon solar battery chip.
Summary of the invention
The utility model purpose provides a kind of solar module, by the improvement of structure, improves the stability of solar module under the hot spot situation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of solar module, comprise framework, panel, base plate, and be arranged in the framework solar cell chip arrays by panel and base plate clamping, described solar cell chip arrays is 6 row, 10 row, be electrically connected by welding between the adjacent cell sheet, two battery sheets of outermost end are respectively equipped with that positive pole is drawn welding and negative pole is drawn welding, described solar battery sheet is the metalluragical silicon solar battery sheet, in described solar cell chip arrays, with continuous 12 is one group, be divided into 5 groups, every group of adjacent junction is provided with bypass and draws welding, welding is drawn in 4 bypasses and described positive pole is drawn welding, negative pole is drawn welding and is connected in the terminal box together, adjacent drawing connects a bypass diode respectively between welding, be formed in the structure of a described bypass diode respectively in parallel on 5 groups of solar battery sheets thus.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the utility model is divided into 5 groups with solar battery sheet, is provided with 6 and draws welding, and connect 5 bypass diodes, make the bypass battery sheet of each diode reduce to 12, increased the hot spot stability of assembly greatly by general 20.
2, the utility model can adopt metalluragical silicon solar battery sheet cheaply, and size of components, outward appearance and mounting means are identical with existing conventional solar cells assembly, thereby greatly reduces the application cost of solar module.
