Solar Myth Mondays: Solar Doesn’t Work in Cool, Cloudy, or Foggy Climates
Many people have questions about how the operation of solar panels on cloudy or rainy days and are afraid that these devices do not work on days like this. However, this is not a significant concern since the solar cells have ways to work around this problem.
FACT: Solar panels work just fine in ambient light and will produce significant energy in the fog or on cloudy. In fact, solar panels are actually more efficient at cooler temperatures than hot ones. Although this might seem counter-intuitive, consider that solar panels on a rooftop in cool, foggy San Francisco produce only one percent less electricity than one in nearby Sacramento, where it’s sunny and hot. Consider too that Germany leads the world in residential solar right now, and doesn’t have a sunny climate.
