(1) toughened glass, whose function is to protect the power generation main body (such as the battery plate), shall be selected for light transmission: 2. Ultra-white steel treatment.

(2) EVA fixed toughened glass used for bonding and generator main body (e.g., battery), the merits of the transparent EVA material directly affect the life of the components, exposed to the air in the EVA aging yellow, thus affect the light transmittance of the component, thus affect the quality of the component's power in addition to the quality of EVA itself, the component manufacturer of laminating process influence is very big, such as EVA adhesive degree is not up to standard, EVA and toughened glass, the back adhesive strength is not enough, will cause EVA early ageing, affecting the service life of components. The main binding package generator main body and back plate.

(3) the main function of the battery is to generate electricity. The mainstream in the main market of power generation is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages. The equipment cost of crystalline silicon solar cells is relatively low, and the photoelectric conversion efficiency is also high. It is more appropriate to generate electricity in the outdoor sunlight, but the consumption and cost of the cells are very high. Thin film solar cells, very low consumption and battery cost, weak light effect is very good, can also generate electricity under ordinary lighting, but relatively high equipment costs, photoelectric conversion efficiency is more than half of crystal silicon cells, such as solar cells on calculators.

(4) backplate function: sealing, insulation, waterproof (TPT, TPE and other materials are generally used to resist aging. Most component manufacturers have a warranty of 25 years.

(5) the aluminum alloy protective layer pressing part plays a certain sealing and supporting role.

(6) the junction box protects the entire power generation system and plays the role of current relay station. If the short circuit junction box of the component automatically disconnects the short circuit battery string, preventing the whole system from burning out, the most critical part of the cable box is the choice of the diode, which varies according to the type of battery in the component.

(7) silica gel seal function is used to seal the junction of components and aluminum alloy frame, components and junction box. Some companies use double-sided tape, foam instead of silica gel, widely used in China, the process is simple, convenient, easy to operate, and the cost is very low.
