What role does EVA film play in solar panels

EVA film plays a vital role in solar panels.
First of all, it is the bonding material between the solar cell, the glass and the backsheet, which can firmly fix the cell in the module, ensure that the cell will not shift or fall off under various environmental conditions (such as high temperature, low temperature, vibration, etc.), and ensure the stability and reliability of the module.
Secondly, EVA film has good light transmittance, allowing most of the sunlight to pass through and reach the surface of the cell, reducing light loss and improving the photoelectric conversion efficiency of solar cells. Its light transmittance is usually above 90%, which can maximize the power generation capacity of the cell.
In addition, the EVA film has certain insulation properties, which can effectively isolate the electrodes between the cells, prevent electrical faults such as short circuits between the cells, and ensure the electrical safety of solar panels.
In addition, EVA film can also play a role in sealing and moisture resistance, preventing moisture and moisture from invading the inside of the module, avoiding corrosion and damage to the cells, and prolonging the service life of solar panels.
In short, the performance of EVA film in solar panels directly affects the power generation efficiency, stability and service life of solar panels.
