Solar panels generate energy even in cloudy or cold conditions1 (also Ramli et al. 2016). Although cloudy weather may reduce power generation by as much as 45%, substantial energy can still be generated during those conditions (Ramli et al. 2016 and Makrides et al. 2012).
Furthermore, in most instances, cold temperatures do not reduce electricity output at all—and actually increase solar panel efficiency by increasing voltage2 (also Sarmah et al. 2023). Crystalline silicon cells, which comprise approximately 84% of the U.S. market, and cadmium telluride cells, which comprise approximately 16% of the U.S. market, actually perform better in colder weather2. Only amorphous silicon cells, which represent a negligible percentage of the U.S market, experience decreased performance in colder temperatures.

This rebuttal is based on the report "Rebutting 33 False Claims About Solar, Wind, and Electric Vehicles" written by Matthew Eisenson, Jacob Elkin, Andy Fitch, Matthew Ard, Kaya Sittinger & Samuel Lavine and published by the Sabin Center for Climate Change Law at Columbia Law School in 2024. Skeptical Science sincerely appreciates Sabin Center's generosity in collaborating with us to make this information available as widely as possible.
