Abstract
This study evaluates the performance of floating photovoltaic (FPV) systems integrated with single-axis solar tracking (FPVSAT) as an innovative approach to enhancing solar energy capture. By utilizing water bodies for solar installations, FPV systems offer a dual benefit of land conservation and improved energy efficiency due to the cooling effect of the water surface. The incorporation of single-axis solar tracking further optimizes energy generation by dynamically adjusting the panels’ orientation to follow the sun's trajectory. To analyze the system, a mathematical model was developed and validated against experimental results obtained from an FPVSAT prototype tested in Mueang District, Lop Buri, Thailand. Simulations were performed using five-minute interval weather data, with comparisons made between fixed, linear tracking, and azimuth tracking configurations. The results demonstrate that single-axis tracking systems significantly enhance solar energy yield compared to fixed installations, with the azimuth tracking configuration providing the highest efficiency. The study highlights the importance of integrating solar tracking mechanisms into FPV systems, particularly in regions with variable solar conditions, to achieve sustainable energy generation. These findings underscore the potential of FPVSAT technology as a cost-effective and efficient alternative to traditional land-based PV systems.
