Can PV systems produce power on cloudy days?
Yes. Although a PV system may receive 80-90% less sunlight on a cloudy day, the modules can still generate electricity. Do PV systems work well in the cold? Yes. In fact, photovoltaic systems generate more power when the temperature is lower. Because of the shorter hours of daylight and lower angles of the sun in winter, PV modules do generate less energy than in summer.
