The short answer is yes, solar panels work on cloudy days.
Solar photovoltaic (PV) cells will still generate energy even when light is partially blocked or reflected by clouds. But there are a few things to consider when determining how much energy your panels can produce on those particularly overcast days.
IS DIRECT SUNLIGHT REQUIRED TO GENERATE ELECTRICITY?
Sunny conditions typically indicate fewer clouds in the sky, and thus less blockage between the sun and your panels. However, clouds can have a magnifying effect on sunlight thanks to their reflective properties. In some cases, this can improve the performance of your solar panels.
However, direct sunlight is much more reliable for solar energy production. While indirect sunlight on cloudy days will still generate power, direct sunlight gives you a more consistent, maximized energy output. You won’t have to rely on your utility company to power your home as long as you have a consistent energy source, which is less likely on cloudy days.
Direct sunlight also results in your panels generating more energy than you need, which will go back into the city’s grid and provide you with credit via net metering. Fortunately, you can tap into those energy credits to power your home on cloudy days when you need them most.
