The silicon solar modules produced by our company may fall into two kinds, that is, large power modules (ranging from 10wp-165wp) and small power modules (ranging form 0.1wp-10wp). The former mainly uses reinforced glass and aluminum alloy rim. It ischaracterized by large power, high conversion efficiency and long service life. It is widely used in the off-grid solar system,on-gridsolar system, household generating and lighting system, traffic lights and solar lighting lamps; the latter chooses quality importedmonocrystalline or polycrystalline silicon solar chips, using solar resin gum for sealing and PET lamination or glass lamination sealing.It is characterized by portability, flexibility, beautiful appearance, and excellent performance. It is mainly applied to solar lawn lamps,portable power solar handicrafts, electric toys and other small electronic and electrical appliances.
