     Tempered glass: Its role is to protect the main power generation (battery), transparent selection of the requirements: transmittance must be high (generally more than 91%); Eva: The purpose is to bond the fixed tempered glass and the power generation main body (such as the battery film), the quality of the transparent EVA material directly affects the life of the component, the exposure of EVA in the air to aging yellowing, affecting the light transmittance of components, thus affecting the quality of power generation components. In addition to the quality of EVA itself, the component manufacturers of laminating process impact is very large, such as Poly Solar Panel
    Eva adhesive not meet the standards, Eva and toughened glass, backplane bonding strength is not enough, will cause EVA premature aging, affecting the component life.Battery: The main role is to generate electricity, the mainstream of the main market is crystalline silicon solar cells, thin film solar cells, both have advantages and disadvantages of crystalline silicon solar cells, equipment costs are relatively low, but the consumption and the cost of the battery is very high, and the photoelectric conversion efficiency is also high, in the outdoor sun power is more suitable for thin film solar cells, relatively high cost of equipment, but the cost of consumption and battery is very low, photoelectric conversion efficiency relative to crystal silicon cell chip more than half point, but the weak It can also generate electricity in ordinary light, such as a solar cell on a calculator.Poly Solar Panel
    Backplane: The function is used to seal, insulation, waterproof. Generally with TPT, TPE and other materials must be anti-aging, most components manufacturers are guaranteed 25, tempered glass, aluminum alloy generally no problem, the key is in with the backplane and silica gel can meet the requirements. Aluminum Alloy: The protective layer pressure piece, has the certain seal, the support function. Junction box: Its role is to protect the entire power generation system, play the role of the current transfer station, if the component short-circuit junction box automatically disconnect short circuit battery string, to prevent burnout of the entire system junction box is the most critical of the selection of diodes, according to the type of battery chip, the corresponding diode is not the same Poly Solar Panel
    Silica Gel: Sealing function, used to seal components and aluminum alloy border, components and junction boxes at the intersection of some companies using double-sided tape, foam to replace silica gel, the use of silica gel, the process is simple, convenient and easy to operate, and the cost is very low.Poly Solar Panel
