Solar Panels composition and functions of each part (2)

(3) Cells: The main function is to generate electricity. The mainstream in the main power generation market is crystalline silicon solar cells and thin-film solar cells. Both have their own advantages and disadvantages.
Crystalline silicon Solar Panels have relatively low equipment costs, but the consumption and cell costs are high, but the photoelectric conversion efficiency is also high, so it is more suitable to generate electricity under outdoor sunlight.
Thin-film solar cells have relatively high equipment costs, but their consumption and battery costs are very low, but the photoelectric conversion efficiency is more than half that of crystalline silicon cells, but the low-light effect is very good, and it can also generate electricity under ordinary lights, such as calculators On the solar cell.
(4) Backplane: Function, sealing, insulation and waterproof. Generally, TPT, TPE and other materials must be resistant to aging. Most component manufacturers have a 25-year warranty. Tempered glass and aluminum alloy are generally okay. The key is whether the backplane and silica gel can meet the requirements.
