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 up of a plurality of solar battery sheets; Usually the battery sheet is arranged in 10 row, 6 array structures, and panel and base plate adopt high light transmittance ratio glass, are 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.
The utility model content
The utility model technical scheme to be solved is to have poor stability under the situation and a kind of solar module is provided in hot spot to existing solar module, through the improvement of structure, improves the stability of solar module under the hot spot situation.
The utility model technical scheme to be solved can realize through following technical scheme:
A kind of solar module; Comprise framework, panel, base plate and be arranged on the interior solar cell chip arrays by panel and base plate clamping of framework, said solar cell chip arrays is 8 row, 10 row, is electrically connected through 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; In said solar cell chip arrays, classify one group as with one, be divided into 8 groups; Every group of adjacent junction is provided with bypass and draws welding; 7 bypasses draw welding with said positive pole draw welding, negative pole is drawn welding and is connected in the terminal box, adjacently draws between welding and draws that welding is drawn welding with positive pole, negative pole is drawn welding and is connected a bypass diode respectively, is formed on 8 groups of solar battery sheets the structure of a bypass diode of parallel connection respectively thus.
Because the utility model is divided into 8 groups with solar battery sheet, be provided with 7 and draw welding, and connect 8 bypass diodes, make the bypass battery sheet of each diode reduce to 10 by general 20, increased the hot spot stability of assembly greatly.
Description of drawings
Fig. 1 is that the solar module of the utility model is electrically connected sketch map.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with accompanying drawing, further set forth the utility model.
Referring to shown in Figure 1; 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; Wherein the solar cell chip arrays is 8 row, 10 row; Be electrically connected through welding between the adjacent cell sheet, two battery sheets of outermost end are respectively equipped with positive pole and draw welding 16 and draw welding 17 with negative pole, in said solar cell chip arrays; With a row solar battery sheet 1,2,3,4,5,6,7,8 is one group; Be divided into 8 groups, every group of adjacent junction is provided with bypass and draws 9,10,11,12,13,14,15,7 bypasses of welding and draw welding 9,10,11,12,13,14,15 and draw welding 16, negative pole with said positive pole and draw welding 17 and be connected in the terminal box and (do not draw among the figure); Adjacently draw welding 9, between 10, adjacently draw welding 10, between 11, adjacently draw welding 14, between 15, adjacently draw welding 12, between 13, adjacently draw welding 13, between 14, adjacently draw welding 11, between 12 and draw welding 9 and draw between the welding 16 with positive pole, draw welding 15 and draw welding 17 with negative pole and be connected a bypass diode 18,19,20,21,22,23,24,25 respectively, be formed on 8 groups of solar battery sheets the structure of a bypass diode of parallel connection respectively thus.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
