This is the case from solar glass through to backsheets. The use of fluoropolymers in backsheets supplied to the industry has some worried about toxicity issues when modules come to their end of life.
Last November the Silicon Valley Toxics Coalition (SVTC) released its “solar scorecard,” providing a ranking of 37 solar module manufacturers with regards to their actions and words when it comes to sustainability.
