They don’t work when the sun isn’t shining
Solar panels are most efficient on sunny days, particularly around noon, when the sun is at its highest point and clear skies provide vast amounts of daylight, but they are still able to generate electricity when the weather is cold or even cloudy during the winter months. The reason for this is that panels are made up of solar photovoltaic cells (pv) that generate electricity from light across the light spectrum, including wavelengths that are invisible to the human eye and pass through clouds, as well as visible sunlight.
