No evidence of PFAS leaching from solar panels, study finds
Researchers in the United States reviewed claims about PFAS in solar panels and found that while fluoropolymers may be used in limited components like backsheets or coatings, there is no confirmed evidence of PFAS leaching from commercially deployed modules. The study highlights widespread confusion between different PFAS types and emphasizes the need for clearer communication and transparency around fluoropolymer use in PV technologies.
Solx and Caelux announce partnership to offer domestic perovskite-silicon tandem solar modules
The companies say they will supply 3 GW of Solx Aurora modules — which combine domestic silicon cells from Suniva and a top layer of Caelux “Active Glass” to reach 28% efficiency — with commercial volumes available in the U.S. market by 2027.
California’s regressive rooftop solar policy hit with second appeal to State Supreme Court
Rooftop solar advocates are making a final stand at California’s highest court, arguing that state regulators have been given a free pass to dismantle the industry. After a lower court recently upheld the state’s controversial solar policy for a second time, environmental groups are calling on the Supreme Court to step in and enforce the law.
