Polycrystalline silicon solar panel components

Polycrystalline silicon solar panel components

1 toughened glass its role to protect the main power generation (such as solar cells), the selection of light is required, 1 light transmittance must be high (generally more than 91%); 2 super white tempered

2 EVA used to bond the fixed glass and the main power generation (such as solar cells), the merits of transparent EVA material directly affect the life of the components exposed EVA in the air is easy to aging yellow, thus affecting the transmittance of the components, Thus affecting the quality of power generation components in addition to the quality of EVA itself, the component manufacturers laminate process is also very large impact, such as EVA glue degree does not meet the EVA and toughened glass, backplane adhesive strength is not enough, will lead to premature aging EVA , Affect the component life.

3 The main role of the battery is to generate electricity, the main power generation market is the mainstream of crystalline silicon solar cells, thin film solar cells, both have their own advantages and disadvantages of crystalline silicon solar cells, equipment costs are relatively low, but the cost and cell costs High, but also high photoelectric conversion efficiency, the power generation in the outdoor sunshine more suitable thin-film solar cells, the relative cost of equipment is relatively high, but the cost and low battery costs, but the photoelectric conversion efficiency relative to crystalline silicon cells more than half, but weak The light effect is very good, in ordinary light can also generate electricity, such as the calculator on the solar cell.

4 EVA role as above, the main bonding package power generation and backplane

5 backplane role, sealing, insulation, waterproof (generally use TPT, TPE and other materials must be resistant to aging, most component manufacturers are warranty 25 years, tempered glass, aluminum alloy generally no problem, the key is with the backplane and silicone Is it able to meet the requirements?

6 aluminum protective laminate, from a certain seal, support role

7 junction box to protect the entire power generation system, play the role of current transfer station, if the components short-circuit Junction box automatically disconnect the short circuit to prevent burnout The entire system junction box is the most critical choice of diodes, according to the battery Different types, the corresponding diode is not the same.

8 silicone rubber seal, used to seal components and aluminum frame, junction boxes and components Some companies use double-sided tape, foam instead of silica gel, China's domestic use of silica gel, the process is simple, convenient and easy to operate, and Low cost.
