Abstract

There has been an increasing rise in the demand for an alternative source of electricity due to the effects of fossil fuels on our environment and humans. Renewable energy has been a sought-after source of energy due to its efficiency, environmental friendliness, and reliability. A small-scale implementation of a Photovoltaic system is the starting point to reducing emissions of greenhouse gases, carbon dioxide, and other unfriendly gases in the environment. Furthermore, it serves as a means of generating energy whenever there is a fluctuation or power off from the utility grid. This project demonstrates the effectiveness of PV systems through accurate load calculation and optimized component design, reducing reliance on fossil fuels, and improving the state of the environment. Data was gathered for accurate sizing of these components and monitoring after installation. A 200W solar panel, a 30A charge controller, a 200AH lithium battery, and a 1000W inverter were used in this project. Post-installation data showed solar output rising from 0.792 to 0.800 kWh, charging currents of 0.9-1.6 A, and battery discharge currents of 2.8–1.2 A with a state-of-charge drop from 100% to 85%, confirming stable performance.
