Do solar panels release more emissions than burning fossil fuels?
Solar panels produce far less emissions than coal or natural gas.
“Lifecycle emissions” counts all aspects of raw materials, manufacturing, transport, installation, operation, and disposal. A major National Renewable Energy Laboratory review of thousands of studies found that while some emissions are generated when solar panels are manufactured and shipped, their lifetime emissions are much lower than fossil fuels. Coal’s lifecycle climate pollution is about 23 times higher than solar power, and natural gas about 11 times higher.
Solar panels also “pay back” their upfront emissions within a few years of operation, offsetting emissions from their manufacture. Since modern panels often last 30 years or more, they will continue to provide decades of low-emissions electricity after their payback.

About fact briefs
Fact briefs are bite-sized, well-sourced explanations that offer clear "yes" or "no" answers to questions, confusions, and unsupported claims circulating online. They rely on publicly available data and documents, often from the original source. Fact briefs are written and published by newsrooms in the Gigafact network.

Skeptical Science is a non-profit science education organization. Our goal is to remove a roadblock to climate action by building public resilience against climate misinformation. We achieve this by publishing debunking of climate myths as well as providing resources for educators, communicators, scientists, and the general public. Skeptical Science was founded and is led by John Cook, a Senior Research Fellow with the Melbourne Centre for Behaviour Change at the University of Melbourne.
