The solar modules lifetime is limited about 25 years before they have to be recycled. So for many of the panels that were produced in the 1980s and 90s this time has come. But how to properly recycle the solar panel ?
Solar panel are composed of photovoltaic(PV) cells that convert sunlight to electricity, when these panels enter landfills, valuable resource go to waste. And because solar panels contain toxic materials like lead that can lead out as they break down, landfill also creates new environmental hazards.
The main components of photovoltaic modules are Aluminum Frame,tempered glass,Solar cell, EVA and Back sheet. Among them, the main component of glass is silica, secondary components are soda, limestone, magnesium oxide,alumina, mirabilite,carbon.EVA Encapsulant is mainly ethylene-EVA ethylene copolymer.The core components of solar cell are mainly monocrystalline silicon and polycrystalline silicon. The main material of the frame is aluminum. The back sheet is composed of two-layers PVF films and one-layer PET film. More than 90 percent of these materials can be recycled.
