FAQ: Do solar hot water systems work when it's cloudy?

Your solar thermal collectors will still absorb a bit of heat on cloudy days, but won't operate as well as they do when it's sunny out. Solar hot water systems typically include a back up water heater that you can use if you experience a few cloudy or rainy days in a row.
