Abstract

The invention discloses a slice solar module which comprises a welding strip, bus bars and solar cells, the bus bars are connected with the solar cells through the welding strip, the bus bars comprise a plurality of first bus bars and a plurality of second bus bars, the first bus bars are located on the upper portion and the lower portion of the module, and the second bus bars are located in the middle of the module. The first bus bar comprises a first area and a second area, a plurality of holes parallel to the short edge direction are formed in the single side of the first area, no hole is formed in the second area, the second bus bar comprises a third area and a fourth area, a plurality of holes parallel to the short edge direction are formed in the double sides of the third area, and no hole is formed in the fourth area. Through the improvement of the bus bar structure, the electrical connection reliability of the welding strip and the bus bar is greatly improved, the internal current and series resistance of the assembly are reduced, and the maximum output power and reliability of the assembly are improved.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a sliced ​​solar module. Background technique [0002] As a clean and renewable new energy, solar energy has received more and more attention, and its application is becoming more and more extensive. At present, one of the most important applications of solar energy is photovoltaic power generation. Photovoltaic power generation uses the photovoltaic effect to directly convert solar energy into electrical energy. The basic unit of photovoltaic power generation is a solar cell. In a specific application, a plurality of solar cells are usually formed into a solar cell module, and then each solar cell module is connected. constitute the overall current output. [0003] Conventional photovoltaic modules are basically composed of toughened glass, solar cells and backplane, and EVA encapsulation material is provided between the toughened glass and solar cells, solar cells and bac...
