Pros of Solar Battery Storage 1. Backup Power. A battery backup system ensures that you have power during a grid outage, providing you with electricity for a limited period of time. The amount of backup power you have, however, is determined by how much power is extracted from the battery system and for how long. This will also be influenced by

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.
In any photovoltaic system that includes batteries, the batteries become a central component of the overall system which significantly affect the cost, maintenance requirements, reliability, and design of the photovoltaic system.
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.
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.
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.
