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.
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.
With the advance in technology and the increase in the market, the cost of solar PV modules is decreasing whereas the cost of batteries is becoming a significant part of a standalone system. Non-optimal use of batteries can result in the reduced life of such a significant device in the system.
A photovoltaic system for residential, commercial, or industrial energy supply consists of the solar array and a number of components often summarized as the balance of system (BOS).
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.
