Storing costs electricity: The issue of conversion losses
No matter how you look at it, storing energy in a battery costs electricity! Usually it is own electricity from the photovoltaic system that is lost through one conversion or another. For a normal AC-coupled system, we have roughly calculated this and come up with an energy efficiency of approx. 70%. So the energy losses are about 30%.

How do solar cells work? Photovoltaic cells explained
PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.
