Photovoltaics
To improve solar panels’ long-term performance and resistance to temperature humidity conditions,they need to pass the environmental tests per IEC61215(for PV modules made from silicon crystal,IEC61646(for PV modules made with thin-film polymers),UL-1703(for flate-plate photovoltaic modules and panels).The environmental tests include thermal cycling test,damp heat test,humidity freeze test.
