Abstract

This project explores the development of a water-based cooling system to enhance the energy efficiency of floating photovoltaic (FPV) systems, a sustainable solution for urban areas facing land shortages and growing energy demands. Elevated temperatures, a challenge for FPV systems, reduce panel efficiency and energy output. The proposed system integrates polycrystalline silicon solar panels, lightweight heat-resistant pipes, and an Arduino-based real-time monitoring system to optimize water flow and cooling performance. Experimental results revealed a significant reduction in panel temperature by 12.5%, resulting in a 15.3% improvement in energy efficiency compared to non-cooled panels. The cooling system also achieved an 18.7% reduction in water evaporation rates, contributing to environmental conservation. Economic analysis confirmed the system's viability, demonstrating reduced operational costs and a favorable payback period, highlighting its potential for large-scale deployment. This study underscores the effectiveness of water-based cooling in improving FPV system performance, advancing renewable energy technologies, and supporting global sustainability goals through innovative thermal management solutions.
