Abstract

An appropriate floating Photovoltaic FPV system cooling strategy that makes use of the surrounding water body can assist to avoid performance deterioration and increase the lifespan of standalone systems. Specifically, experimental research is conducted to investigate a variety of novel passive cooling approaches for such systems. The research focuses on various configurations of modified FPV, including a partially submerged floating (PSPV-AF) system with attached fins (AF) that was compared to a partially submerged floating system without fins (PSPV) and a bare conventional floating system (FPV-R), for which a comprehensive performance analysis and optimization were conducted. The suggested modified system with attached fins was then tested in a floating setup in outdoors real-circumstances. The results confirmed the PSPV-AF system's superiority over earlier techniques in the literature. At a submerged area ratio (AR) of 20 %, described as the percentage value of the underwater area to module area, it outperforms the FPV-R in terms of operating temperature reduction by about 19.07 %. The suggested module's performance is enhanced with an optimal submerging ratio of AR = 20 %, resulting in a 24.02 % increase in output power and a 22.24 % increase in electrical efficiency compared to FPV-R.
