Photovoltaic solar panels have become a feasible solution to environmentally friendly power generation due to the growing demand for energy from renewable sources. Nevertheless, achieving optimal performance of these systems in the face of fluctuating environmental conditions continues to be a formidable task. This research aims to optimise solar photovoltaic systems by combining a boost Maximum Power Point Tracking (MPPT) regulator with grid connection and battery backup. The issue statement focuses on improving the efficiency and dependability of solar energy generation, particularly in situations where there are varying levels of sunlight and a consistent temperature. The process entails a thorough system design that integrates a DC-DC boost converter, which is regulated by a Perturb and Observe (P&O) based MPPT controller. This controller is used to optimise power extraction from the solar panels. In addition, a bidirectional converter that converts DC to DC is used to control the charging and discharging of the battery. This converter ensures that extra solar energy is efficiently used and also provides backup power when there is not enough sunlight. A highly advanced controller, consisting of a phase-locked loop (PLL), PI controllers, as well as reference signal generators, allows for smooth integration with both the AC grid and the load. The effectiveness of the suggested system is demonstrated by the results obtained from MATLAB/Simulink simulations. The performance charts demonstrate enhanced efficiency and reliability in solar PV output, boost MPPT effectiveness, storage behaviour and grid interaction.
