Solar panels installed on your roof work during daylight hours. When the sun is shining directly onto them, sunlight can be converted into electricity. Your solar panel doesn't work at night because there is no sunlight to convert to electricity and solar panels can’t generate power in darkness.
However, [RE]NEW ERA offers solutions to power your home in an environmentally friendly way, even at night. Your solar panels can generate so much power during a sunny day that any excess power you don’t use immediately can be conserved and stored into a back up battery system. So that you could take full advantage of the sun's energy and also use it at night.
