Solar photovoltaic module and manufacturing method for convergence belt leading wires of same

Abstract

The invention discloses a method for manufacturing convergence belt leading wires of a solar photovoltaic module. The method comprises the following steps of: 1, welding a convergence belt and the leading wires of the convergence belt; 2, welding the convergence belt to welding belts led out of different areas of the solar photovoltaic module respectively, wherein the convergence belt at least comprises a first convergence belt and a second convergence belt which are welded with the different welding belts; 3, laying ethylene-vinyl acetate copolymer (EVA) strips and back plate strips between the different convergence belts as well as between the convergence belts and batteries of the solar photovoltaic module; and 4, laying EVAs and back plates on the solar photovoltaic module. When the convergence belt and the welding belts are welded in the step 2, gaps are formed between the first convergence belt and the second convergence belt in the height direction. According to the method, the gaps are formed between the convergence belts, and lead-out modes for the convergence belts can be improved, so that the problem that the convergence belts are superposed crosswisely is solved, and the quality of the solar photovoltaic module is guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaics, in particular to a solar photovoltaic module and a method for manufacturing the lead wires of the busbar. Background technique [0002] The solar photovoltaic market has also experienced the process from birth to maturity like other markets. As this field becomes more and more mature, the competition in the photovoltaic market is becoming more and more fierce. How to reduce costs in terms of raw materials, production, personnel, and energy consumption It is a difficult problem facing every enterprise. [0003] At present, when solar photovoltaic modules are laid, manual welding of ribbons and confluence belts is used, which undoubtedly increases the influence of human factors on the modules. Please refer to figure 1 , the busbars include a first busbar 1 and a second busbar 2, which are arranged symmetrically on the left and right sides of the module respectively, corresponding to d...

Problems solved by technology

However, there is a problem that cannot be ignored in the above scheme, that is, there is a cross-overlapping phenomenon between the first confluence strip 11 and the second confluence strip 12, so after the EVA strip 14 and the back panel strip 15 are laid, this part will become It is very thick and uneven, so the lamination effect of the components after lamination is not very good, and there will be risks of air bubbles and bulges, which will affect the quality of the components
