Battery Details

Solar PV systems can use a battery to store extra electricity for later use. This helps further reduce total electricty demand from the grid. Systems without a battery can still contribute to the reduction of electricity demand by providing part of the households electricity needs.

The percentage of solar PV systems with a battery is described by the Battery Penetration Rate.

The Battery Capacity describes the amount of charge that can be stored in the battery. Increasing the battery capacity helps reduce the total electricity demand from the grid.
