DO SOLAR SYSTEMS NEED BRIGHT SUNSHINE TO WORK?

Solar PV panels on the roofs of homes and businesses generate clean electricity by converting the sunlight’s energy. The more energy in the sunlight received by the panel, the more electricity is being generated.

Even in overcast conditions solar modules still generate electricity, eventhough less than on a really bright day. In lay man terms – the brighter (not necessarily hotter) the sun (high irradiance) the better the electricity output generated.
