In Section 4, the simulation During [3 s, 4 s], the solar power and battery power supply the load as a hybrid source. Then, in [4 s, 5 s], the load demand is larger than the power generated from the PV panel, so the battery supplies the load. After 5 s, there is no solar power and the load is completely supplied by the battery.

In a standalone solar PV system, different types of batteries are used, and they come with different types of capacity. The battery capacity measures the charge contained by a battery in Ampere-hour (Ah). This rated capacity is represented as the maximum Ah deliverable by a fully charged battery under specific conditions, such as:
Batteries are of two main types—primary or non-rechargeable batteries and secondary or rechargeable batteries. In all PV systems, rechargeable batteries are used. Standalone or off-grid PV systems are those that are not linked to the grid. Such systems use batteries for storing energy.
Unlike conventional batteries, rechargeable batteries used in solar PV systems must function under different conditions. Due to the intermittency of solar energy, these batteries undergo irregular charging and discharging.
Batteries are a vital component of any solar PV system, with a considerable impact on the PV system's cost, reliability, maintenance needs, and design. They produce electrical energy from the stored chemical energy, and the electricity can be used for any application when required.
