Solar energy is a suitable replacement for fossil fuels due to its superabundant availability and lesser cost. As the Photovoltaic (PV) array output is non-linear, applying the concept of Maximum Power Point Tracking (MPPT), the efficiency of the PV system can increase. Due to the faster response advantage of the perturbation and observation (P&O), MPPT algorithm implementation is selected. A bidirectional buck-boost converter operation to establish charging and discharging the battery to feed the power to load is controlled with a PI controller. Battery discharges and acts as a source, and the bidirectional converter operates as a boost converter. During the charging phase of the battery, the bidirectional converter acts as a buck converter and the battery acts as a load. Operation of the inverter with sinusoidal PWM to obtain AC power to the load is realized. Power supply to the load from the solar PV module and/or ESS corresponding to different modes of operation are simulated and analyzed. The method of analyzing the solar PV system is explained. The analysis presented is a prerequisite and will help in identifying the scope of modification of the system for future requirements.
