Photovoltaic panels

Monomer solar cells cannot be used directly do the power. As a power source must be a number of monomer battery connected in series, in parallel and tightly encapsulated into components. Solar energy battery components ( Also called solar panels) Is the core part of solar power systems, as well as the most important part of the solar system. Its function is to convert solar energy into electric energy, or sent to stored in the storage battery, or promote work load. Quality and cost of solar panels will directly determine the quality and cost of the whole system. 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) , transparent EVA material quality directly affects 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 toughened glass, the back adhesive strength is not enough, will cause EVA early old, affecting the service life of components.

 3) Cell main effect is power generation, power generation main market is the mainstream in the crystalline silicon solar cells, thin film solar cells, both have their own advantages and disadvantages of crystalline silicon solar cells, equipment cost is relatively low, but consumption and cell costs are high, but the photoelectric conversion efficiency is high, outside the sun power is more suitable for thin film solar cells, relatively high equipment cost, 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, can also power in ordinary light, such as the solar cells on the calculator. 

 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, component 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 connection box is most critical in the selection of diodes, depending on the type of component inside the cell is different, different corresponding diode 8) Silicone sealing function, which is used to seal components and aluminum alloy frame, the component and junction box at the junction of some companies use double-sided tape, foam instead of silicone, domestic commonly used silica gel, the craft is simple, convenient, easy to operate, and low cost.
