In order to optimize solar energy efficiency, this study describes a grid-connected photovoltaic (PV) system that has been coupled with an interleaved boost converter. Optimizing solar power plants' performance has grown crucial as the demand for renewable energy rises. The voltage from the PV array is increased to the necessary grid voltage using an interleaved boost converter, which is renowned for its capacity to lower ripple and improve efficiency. In order to ensure that the PV system always runs at its peak power production, this system uses Maximum Power Point Tracking (MPPT) methods to dynamically adapt to changing solar irradiation and temperature conditions. Current ripple is decreased by interleaving the converter phases' switching, which lowers electromagnetic interference (EMI) and increases dependability. According to simulation and experimental data, the suggested system guarantees stable operation with fewer components, lowers losses, and greatly increases energy conversion efficiency. The system's capacity to adjust to changing environmental circumstances is further improved by the integration of an advanced MPPT algorithm with the interleaved boost converter. This work presents a viable way to improve grid-connected PV systems' energy efficiency, which will help make solar power generation more economical and sustainable. The proposed strategy is validated through simulation using MATLAB 2021a /Simulink software.
