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.
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.
Lead ac id battery with deep discharge is commonly used for PV ap plications. Gel type maintenance free operation is required. hydride batteries are used. The life time of the batteries varies from 3 to 5 years. The life time depends on parameters. 1. Low cost ...
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.
Such rechargeable batteries with many cycles are widely applicable in solar PV applications as they ensure the continuity of the power to the load in the presence of low or even no sunlight, without which the implementation of a standalone solar PV system would be very unreliable and difficult.
Solar battery technology stores the electrical energy generated when solar panels receive excess solar energy in the hours of the most remarkable solar radiation. Not all photovoltaic installations have batteries. Sometimes, it is preferable to supply all the electrical energy generated by the solar panels to the electrical network.
