Do Solar Panels Work Without Sun? How Do?
We all know that solar panels need sunlight to work. But what happens on a cloudy day, or at night? Do solar panels still generate electricity even when the sun isn’t shining? The short answer is yes, solar panels can still work on cloudy days and even at night. However, they will not be as effective as they are on sunny days. Solar panels rely on a phenomenon called the photovoltaic effect to generate electricity. This is when light particles (photons) knock electrons loose from atoms, creating an electric current. So while sunlight is the best source of photons for generating electricity, any kind of …
