Photovoltaic systems often produce more electricity than needed at the time. The sun shines during daytime hours rather than at night when electricity is needed. Fortunately, solar power can be stored in a solar battery that serves as an energy reservoir.
If you are interested in home solar panels, you should check if your roof or property is suited for an installation. Check if there is enough sun, if roof orientation and pitch are adequate and if you need a planning permission.
