Do solar panels work on cloudy days?
On a clear day, your solar panels practically hum with energy and possibility. But on a partly-cloudy day, as we’ve depicted here, production can drop by around 10~20.
The Edge of Cloud Effect
When fluffy cumulus clouds pass over the sun, the wispy edge of the cloud can actually magnify a sunbeam, causing panel output to exceed the rated performance.
Every part of the lower 48 states gets enough sun to save hundreds of dollars per year.
