PV panels mainly rely on the Crystalline Silicon (c-Si) technology. This technology represents around 95% of the market share and is expected to stay the dominant technology in the near future in addition to more emerging ones such as: Cadmium Telluride (CdTe), Copper Indium Gallium Selenide (CIGS), and Perovskite.

C-Si cells dominate the PV market and glass is the main processed material in terms of weight, while polysilicon and silver are most important in terms of value.

Environmental footprints were reduced by 60-75% since 2011.

This assessment was based on data from 2017-2019 with a module efficiency of 19.5, an average European annual yield of 975 kWh/kWp, assuming 0.7%/yr linear degradation rate, 30 year lifetime for the panel and 15 year for the inverter.
