the trend of eva solar photovoltaic film

the future trend of eva solar film: eva solar film meter length and weight

according to the width, the density is 0./cm3, approximately. different widths and different weights

the trend of eva solar films in 2020: how likely is it that photovoltaic eva films will be replaced?

in recent years, with the improvement of photovoltaic technology, double-glass solar modules have developed rapidly. compared with traditional single-glass modules, double-glass modules use photovoltaic glass instead of backsheets, which greatly improves the module's water vapor resistance, corrosion resistance, fire prevention, and sand-proof wear resistance. at the same time, because double-glass modules have a certain degree of light transmittance, they can be used for agricultural/fishery light complementation and general buildings have expanded the application scope of solar photovoltaic modules.

please be patient and read this paragraph, because it is very important! !

compared with single-glass modules, double-glass modules have greater advantages.

since the water vapor transmittance of glass is almost zero, there is no need to consider the problem of water vapor entering the module and inducing hydrolysis of the eva film. it is especially suitable for photovoltaic power stations in areas with higher humidity such as seaside and waterside;

secondly, glass has good wear resistance, weather resistance, and corrosion resistance, so that the components can be used in areas with heavy sandstorms, acid rain, and salt spray;

third, the fire protection level of double-glass modules has been improved, making it suitable for areas such as residential buildings and factories that need to avoid fire hazards;

fourth, the high insulation of glass makes the components suitable for higher system voltages and saves the system cost of the power station.

at present, the encapsulating films used for double-glass modules mainly include eva film and poe film. eva film is an ethylene-vinyl acetate copolymer. it has the advantages of low melting point, good fluidity, high transparency, and mature lamination process. it is currently the main packaging material for double-glass components.
