1) Its role to protect the power subject (toughened glass Such as cell) , pervious to light the choose is required, 1. High light transmittance must ( Generally more than 91%) ; 2. Super white steel processing 2) EVA fixed toughened glass used for bonding and power generation ( Such as cell) ,
1) Toughened glass' Toughened glass ( 钢化玻璃/增强玻璃) Surface with compressive stress of the glass. 】 Its role to protect the power subject ( Such as cell) , pervious to light the choose is required, 1. High light transmittance must ( Generally more than 91%) ; 2. Super white steel processing
2) EVA【 Eva can refer to an evangelion anime series, can also refer to Eva all the body. 】 Fixed toughened glass used for bonding and power generation ( Such as cell) , 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, component manufacturer of laminating process influence is very big, such as EVA adhesive degree is not up to standard, EVA and bonding strength of toughened glass, backboard 【 Adhesive bonding strength is refers to the unit on the surface of stick relay, bonding strength mainly includes rubber cohesive strength and bonding strength between the rubber and glued surfaces. 】 Enough, EVA will cause early aging, affecting the service life of components.
3) Solar panel prices leading role is power generation, power generation main market is the mainstream in the crystalline silicon solar cells, thin film solar cell' Solar cell is divided into crystalline silicon and amorphous silicon, class of silicon cells, and can be divided into single crystal cell and polycrystalline silicon solar cell; The efficiency of monocrystalline silicon is polycrystalline silicon also has difference. 】 , both have their own advantages and disadvantages. Crystalline silicon solar cell, the equipment cost is relatively low, but consumption and cell costs are high, but the photoelectric conversion efficiency is high, in the outdoor sun power is good; Thin film solar cells, and relative equipment cost is higher, but low consumption and cost of batteries, but the photoelectric conversion efficiency relative to crystalline silicon cells in half, but weak light effect is very good, in the ordinary light also can power generation, such as the solar cells on the calculator. Solar street lamps light pole
4) EVA role as above, the main bonding encapsulation power main body and the back
5) Lagging effect, sealing, insulation, waterproof ( With TPT, TPE and so on material must be resistant to ageing, most of the components manufacturers warranty for 25 years, toughened glass, aluminum alloy is generally no problem, the key is in the back and the silicone can meet the requirements. )
6) Aluminium alloy layer pressure, seal, support role
7) Junction box to protect the whole power generation system, have the effect of current transit, if the component junction box automatically disconnect short circuit battery series, to prevent burn out the whole system. Junction box is most critical in the selection of diodes, depending on the type of component inside the cell is different, the corresponding diode is not the same
8) Solar panel prices silicone sealing function, which is used to seal components and aluminum alloy frame, the component and junction box junction. Some companies use double-sided tape, foam instead of silicone, which is widely used in domestic silica gel, the craft is simple, convenient, easy to operate, and low cost.
