In a standalone photovoltaic system battery as an electrical energy storage medium plays a very significant and crucial part. It is because in the absence of sunlight the solar PV system won’t be able to store and deliver energy to the load.
Battery storage can significantly increase the self-consumption of solar PV by households. The graph below shows an estimate of the solar self-consumption for a household with annual electricity consumption in the range 3,000 to 3,499 kWh and annual solar PV generation between 2,700 and 2,999 kWh.
The charge storage capacity of the battery is reflected by its physical size. Small size batteries have small storage of charge while large size batteries have high storage of charge. One of the most commonly used batteries in the solar PV system is the lead-acid battery.
The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.
Different parameters of the battery define the characteristics of the battery, which include terminal voltage, charge storage capacity, rate of charge-discharge, battery cost, charge-discharge cycles, etc. so the choice to select batteries for a particular solar PV system application is determined by its various characteristics.
Usually, batteries with 6 V and 12 V are available for the solar PV system application. Now each battery is made up of cells and depending on the material its terminal voltage of the cell is determined.
