Solar energy is a free green power obtained from sunlight every day. Solar photovoltaic modules convert solar energy into electricity during the day.
Appearance materials (choose one from the following):
PET: The English name is Polyethylene terephthalate, abbreviated as PET. It is divided into two types: frosted and bright, located at the outermost layer of the solar panel. The primary task is to maintain the solar cell and high transmittance to ensure that the solar panel generates electricity.
ETFE: English name is Ethylene Tetra Fluoro Ethylene, abbreviated as ETFE, a tetrafluoroethylene copolymer. It has a uneven surface when laminated, with a lifespan longer than PET but shorter than glass, resulting in the same effect.
Glass: It is the outermost layer of solar panels and must be sturdy and have good transparency in order to achieve better panel functionality. The primary function of tempered glass is to maintain solar cells from the effects of harsh weather, dirt, and dust.
EVA: EVA sheet or “ethylene vinyl acetate” is used to bond and encapsulate battery cells and external raw material layers. It should be durable and can withstand extreme temperatures and humidity.
Solar panels: An important component of solar panels, which are strung together to make solar panels, including welding, packaging, installing them on metal structures, testing, etc. The efficiency of solar panels is directly proportional to the efficiency of solar panels. The cost and efficiency of solar cells affect the overall functionality of solar panels.
EVA: EVA sheet or “ethylene vinyl acetate” is used to bond and encapsulate battery cells and the reverse raw material layer. It should be used and can withstand extreme temperatures and humidity.
Negative raw materials (choose one from the following):
PET: The final layer of the panel, providing mechanical maintenance and electrical insulation. It is essentially a maintenance layer.
PCB: The final layer of the panel, providing mechanical maintenance and electrical insulation. It is essentially a maintenance layer. There is also a circuit section above it.
Border: The aluminum structure is also a key component, as it provides structural strength for the panel. Advocate the use of structures made of sturdy but lightweight materials. It should be hard and able to withstand extreme conditions such as strong winds and external forces. Another is to maintain the four corners of the glass panel, which will not cause the entire piece to shatter in case of collision.
Junction box: The junction box is fixed on the opposite side of the panel. It is the central point of interconnection between electrical wires and solar panels. Maintain the wiring of the solar panel to prevent water ingress and provide waterproofing. The above are the important components of solar panels: exterior materials+EVA+battery cells+EVA+reverse materials=solar panels.
