Scaling-Up Global Solar Panel Manufacturing Sustainably

A new life‑cycle assessment published in Nature Communications shows that decarbonising the electricity used to make silicon solar panels could cut manufacturing emissions by up to 8.2 gigatonnes of CO₂ – roughly 6.3 % of the remaining global carbon budget. The research, conducted by four UK universities, finds that higher cell efficiencies also lower climate impact by 6.5 % while raising critical‑mineral depletion by 15.2 % due to increased silver use. By 2035, panels installed at terawatt scale could avoid at least 25 gigatonnes of CO₂ over their operational life. The study quantifies 16 environmental impact categories, offering a roadmap for greener photovoltaic supply chains.
