Optimisation of home grid-connected photovoltaic systems: performance analysis and energy implications

Abstract

In the increasing need for renewable energy, grid-connected photovoltaic (GCPV) systems at home are a promising solution to reduce dependence on fossil fuels. This article examines the optimization of home GCPV systems, focusing on performance analysis and the resulting energy implications. It also analyzes the performance of a photovoltaic system with a capacity of 3000 Wp connected to the electricity network to people's homes. Through case studies using empirical data and computer simulations, this research evaluates various GCPV system configurations to determine the most energyefficient scenario. Without the influence of shadows, this system is designed to meet daily household energy needs with seasonal modulation. The simulation results show annual energy production of 4446 kWh and energy use of 3379 kWh, with a performance ratio of 83.79% and a diesel fraction of 55.40%. This article discusses the simulation methodology, results, and implications of using PV systems in the context of energy efficiency and sustainability.
