Abstract: The rapid expansion of solar photovoltaic (PV) technology has intensified the need for innovative installation approaches that enhance energy yield while minimizing land usage and performance losses due to environmental conditions. Among emerging solutions, Floating Solar Photovoltaic (FPV) systems have gained significant attention as an alternative to conventional Fixed Ground Mount (FGM) PV installations. This paper presents a comprehensive comparative performance analysis of FGM and Floating Solar PV systems based on experimental data collected under identical climatic conditions. The study evaluates key environmental parameters, electrical output characteristics, and performance indicators including irradiance, ambient temperature, module cell temperature, voltage, current, power output, efficiency, performance ratio (PR), capacity factor (CF), and fill factor (FF). The results demonstrate that Floating Solar PV systems consistently outperform Fixed Ground Mount systems due to enhanced natural cooling effects, leading to reduced thermal losses, improved voltage stability, higher power output, and superior overall performance. The findings confirm the technical advantages of floating PV installations, particularly in regions experiencing high humidity, elevated temperatures, and limited land availability.
