Solar energy is free green power that comes from sunlight for free every day. Solar PV modules convert solar energy into electricity during the day. Components and effects of solar panels:
Exterior raw materials (choose one of the following):
PET: English name Polyethylene terephthalate, abbreviated PET. Divided into two types, frosted and bright, it is located in the outer layer of solar panel Z, and the first thing is to maintain solar cells and high light transmittance to ensure that solar panels generate electricity.
ETFE: English name is Ethylene Tetra Fluoro Ethylene), referred to as ETFE, tetrafluoroethylene copolymer. Its laminated appearance is uneven, the life will be longer than PET, but shorter than glass, the effect is the same.
Glass: It is the Z outer layer of solar panels, which must be strong and have good light transmission to obtain better panel function. The primary function of tempered glass is to maintain solar cells from harsh climates, grime and dust.
EVA: EVA sheet or "ethylene vinyl acetate" is used to bond encapsulated cells and surface raw material layers, which should be used and can withstand extreme temperatures and humidity.
Solar panels: An important part of solar panels, solar cells strung together to make solar panels, including welding, encapsulation, mounting them on metal structures, testing, etc. The efficiency of solar panels is proportional to the efficiency of solar cells. The cost and efficiency of solar cells affect the overall function of solar panels.
EVA: EVA sheet or "ethylene vinyl acetate" is used to bond encapsulated cells and reverse raw material layers, which should be used and can withstand extreme temperatures and humidity.
Reverse raw materials (choose one of the following):
PET: The Z final layer of the panel, which provides mechanical maintenance and electrical insulation. It is essentially a maintenance layer.
PCB: The Z final layer of the panel, which provides mechanical maintenance and electrical insulation. It is essentially a maintenance layer. Another is that there will be a circuit section on top of it.
Bezel: The aluminum structure is also a key component, as it provides structural strength to the panel. The use of structures made of strong but lightweight materials is advocated. It should be hard and can withstand extreme conditions such as strong winds and external forces. Another is to maintain the four corners of the glass plate, which will not cause the whole piece to shatter in the event of a collision.
Junction box: The junction box is fixed on the reverse side of the panel. It is the central point where the wires are interconnected with the solar panels. Maintain that the wiring of the solar panel does not enter the water to play a waterproof effect. The above is the important part of solar panels: surface raw materials + EVA + cell + EVA + reverse raw materials = solar panels.
