A common concern we hear from homeowners: “Do solar panels stop working when it’s cloudy?” The short answer—no, they don’t.

Solar Panels and Diffused Light
While panels are most efficient in direct sunlight, they still generate electricity under overcast skies thanks to diffused light. Energy production may drop by 10–25% depending on cloud density, but it doesn’t stop entirely.

Battery Backup Helps Bridge the Gap
Pairing solar with battery storage ensures you have power even when the sun isn’t fully out. It’s particularly useful for homes on time-of-use rates or in regions with frequent cloud cover.

Technology Improvements
Today’s panels are more efficient and better at capturing a broader spectrum of light. Some are designed to perform better in low-light conditions, which is ideal for areas with variable weather.

Cloudy days don’t shut down your system. With the right panels and storage setup, you can still rely on solar even when the sun isn’t shining at full strength.
