Copper-indium-selenide thin-film PV manufacturer Solar Frontier said that its CIS modules have been certified by TÜV Rheinland as RoHS compliant. Solar panels are exempt from RoHS (which stands for “reduction” or “restriction of hazardous substances) compliance, and Solar Frontier claims to be one of the few manufacturers able to meet the requirements, having completed voluntary testing with TÜV to make it official.
RoHS, which was adopted by the European Union in 2003, sets a 0.01% concentration limit on cadmium, and a 0.1% limit on lead, mercury and three other hazardous substances, for any component of a certified device.
“Solar energy has many environmental advantages in the world’s energy portfolio, but toxicity is an extremely important issue , so Solar Frontier is proud to have taken the initiative with its more eco-friendly product by voluntarily complying with the RoHS directive,” said Wolfgang Lange, managing director of Solar Frontier Europe. “Solar Frontier believes that as solar energy rapidly grows around the world, it is important that environmental standards advance to ensure that solar energy also fulfills its ecological promise.”
