Description
Technical field
This utility model relates to a kind of solar module, especially relates to a kind of leadless environment-friendly type solar module.
Background technology
Solar components has a kind of function converting solar energy into electric energy, is a kind of instrument making full use of solar energy. How to use relatively low cost to reach high efficiency to utilize solar energy, be a research direction in current industry.
Solar module is sequentially overlapped is formed by safety glass, the first encapsulation glue-line, solaode lamella, the second encapsulation glue-line and backboard. Wherein, solaode lamella includes many group solaode strings. Often group solaode string includes multiple solar battery sheet, and the front of each solar battery sheet is provided with main gate line, and its back side is provided with back electrode, by interconnecting strip, multiple solar battery sheets is sequentially carried out connection and forms described solaode string. Specifically, pass sequentially through interconnecting strip the main gate line of previous solar battery sheet to be connected with each other with the back electrode of adjacent solar battery sheet.
Current solar battery sheet main gate line design width is 1.5mm, and the main flow interconnecting strip used in market is 1.6mm. After using the welding of this interconnecting strip, what have that subregion blocks battery surface effectively accepts source region, thus reducing the generating efficiency of solar components, also can improve product cost to a certain extent simultaneously.
Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of leadless environment-friendly type solar module is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of leadless environment-friendly type solar module, it is characterized in that, this battery component includes multi-disc cell piece and interconnecting strip, described cell piece is provided with at least 1 main gate line, described main gate line is connected in series by interconnecting strip, described interconnecting strip width is equal with described main gate line width, is welded to connect after described interconnecting strip and described main gate line being completely superposed.
Described main gate line width is 1.5mm, and described interconnecting strip width is 1.5mm; More than main gate line, interconnecting strip width can cause that cost increases, block battery component simultaneously and receive source region, reduce solar energy output; Can cause that himself resistance increases when interconnecting strip width is less than main gate line width, bring relatively high power loss, therefore interconnecting strip is set to equal with main gate line width, save cost to a certain extent, reduce self-resistance thus reducing power attenuation simultaneously, additionally prevent interconnecting strip from blocking and near main gate line, receive source region, improve solar energy output.
Described interconnecting strip thickness is 0.25mm, it is contemplated that if interconnecting strip thickness crosses conference crushing cell piece during lamination, but the too small meeting of interconnecting strip thickness causes that current-carrying capacity reduces, therefore both optimal choice 0.25mm comprehensive.
Described cell piece is additionally provided with a plurality of thin grid line, described thin grid line is vertical with described main gate line to be connected, described thin grid line width is less than described main gate line width, thin grid line is set and realizes collected current to greatest extent, its width being arranged less than main gate line width thus reducing shading-area simultaneously, improving output.
Described main gate line is provided with 2��5, arranges more interconnecting strip and is conducive to improving the output of solar components.
On described cell piece, main gate line is provided with 3, inevitably results in shading-area on battery component and increases so that output reduces, it is thus preferred to arrange 3 main gate line while increasing main grid number of lines.
Compared with prior art, interconnecting strip width is set to equal with main gate line width by this utility model, thus that reduces material makes consumption, it is effectively controlled the production cost of assembly, another because decreasing the part blocking light source, make solaode can more accept light source, the output of assembly can be promoted.
Accompanying drawing explanation
Fig. 1 is this utility model solar module structural representation.
In figure, 1 is main gate line, and 2 is interconnecting strip, and 3 is thin grid line.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of leadless environment-friendly type solar module, including multi-disc cell piece and interconnecting strip 2, described cell piece is provided with at least 1 main gate line 1, described main gate line 1 is connected in series by interconnecting strip 2, described interconnecting strip 2 width is equal with described main gate line 1 width, is welded to connect after described interconnecting strip 2 being completely superposed with described main gate line 1. Wherein said main gate line 1 width is 1.5mm, and described interconnecting strip 2 width is 1.5mm; More than main gate line 1, interconnecting strip 2 width can cause that cost increases, block battery component simultaneously and receive source region, reduce solar energy output; Can cause that himself resistance increases when interconnecting strip 2 width is less than main gate line 1 width, bring relatively high power loss, therefore interconnecting strip 2 is set to equal with main gate line 1 width, save cost to a certain extent, reduce self-resistance thus reducing power attenuation simultaneously, additionally prevent interconnecting strip 2 from blocking and near main gate line 1, receive source region, improve solar energy output. Described interconnecting strip 2 thickness is 0.25mm, it is contemplated that if interconnecting strip 2 thickness crosses conference crushing cell piece during lamination, but the too small meeting of interconnecting strip 2 thickness causes that current-carrying capacity reduces, therefore both optimal choice 0.25mm comprehensive. Described cell piece is additionally provided with a plurality of thin grid line 3, described thin grid line 3 is vertical with described main gate line 1 to be connected, described thin grid line 3 width is less than described main gate line 1 width, thin grid line 3 is set and realizes collected current to greatest extent, its width being arranged less than main gate line 1 width thus reducing shading-area simultaneously, improving output. Described main gate line 1 is provided with 2��5, and described main gate line 1 is preferably provided with 3, inevitably results in shading-area on battery component and increases so that output reduces, it is thus preferred to arrange 3 main gate line 1 while increasing 1 number of main gate line.
