Product Description

Photovoltaic modules, also called solar panels or photovoltaic panels, are the core components for photovoltaic power conversion in photovoltaic power generation systems. Its function is to convert the radiant energy of sunlight into DC power, which is sent to the battery for storage. It can also be directly used to drive DC load work, or converted into AC power through a photovoltaic inverter to provide power to users or to generate electricity on the grid.

Component materials

1. Glass: ultra-white textured tempered glass, 3.2mm thick, with a light transmittance of more than 91% within the wavelength range of the solar cell spectral response (320-1100nm), resistant to ultraviolet radiation, and the light transmittance does not decrease. The components made of tempered glass can withstand the impact of an ice ball with a diameter of 25 mm at a speed of 23 meters/second.

2. EVA: A high-quality EVA film layer with a thickness of 0.5mm is used as a sealant for solar cells and a connecting agent with glass and TPT. It has high light transmittance and anti-aging ability.

Performance requirements after curing of EVA film for solar cell packaging:

Light transmittance is greater than 90%; cross-linking degree is greater than 65-85%; peel strength (N/cm), glass/adhesive film is greater than 30; TPT/adhesive film is greater than 15; temperature resistance: high temperature 85℃, low temperature -40℃ . ,

3. TPT: The back side of solar cells has basic requirements such as aging resistance, corrosion resistance, ultraviolet radiation resistance, and airtightness.

4. Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical impact.
