These modules currently have an efficiency of 16–22%. The trend of increasing the efficiency of mass-produced PV modules is demonstrated in Figure 7.
When do batteries supply energy in a stand-alone PV system?
In stand-alone systems, batteries are required because of the fluctuating nature of the PV system output. During the nights and periods of low solar irradiation, battery can supply the energy to the load.
