Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
In simple PV systems, where PV module voltage is matched to the battery voltage, use of MPPT electronics is generally considered unnecessary, since the battery voltage is stable enough to provide near-maximum power collection from PV module. A stand-alone system does not have a connection to the grid. Fig. 2.
Several methods have been developed to predict the solar PV array output power. An estimation method used in Ref. proposes that the power output of a PV system is proportional to the insolation levels measured for the surface of a solar cell at any angular position.
PV stand alone or hybrid power generation systems has to store the electrical energy in batteries during sunshine hours for providing continuous power to the load under varying environmental conditions. This article deals with the requirements, functions, types, aging factors and protection methods of battery.
