Solar power, the most popular renewable energy source, encounters several limitations with conventional ground-mounted solar systems due to land use and several environmental factors affecting solar systems efficiency. Floating solar PV systems offer promising solutions by leveraging water bodies cooling effects, reducing land occupancy, preventing biological fouling, and also reducing the evaporating effect of water bodies. The objective of this research study is to conduct a comparative analysis on the performance of floating PV systems against ground-mounted solar systems, evaluating their efficiency and identifying influencing parameters. Utilizing polycrystalline panels mounted on modular rafts for the floating system and ground-mounted units, data collection under varied conditions aims to analyze the effect of floating type solar PV systems. The outcomes of this research contribute insights into enhancing solar power generation efficiency in tropical contexts, particularly in Sri Lanka. If successful, the study could optimize land utilization, increase renewable energy capacity, and utilize alternative spaces for sustainable power generation. After conducting the study the floating solar system was able to gain 2.06% power gain over ground-mounted PV panels. The performance ratio of the floating solar system was comparatively better (89.6%) compared to the ground-mounted PV system (87.79%). Which shows the floating solar PV systems are more productive and effective in tropical countries like Sri Lanka.

An Experimental Study on Efficiency Enhancement of Floating Solar PV Systems in Sri Lanka

Solar photovoltaics (PV) is the most rapidly growing source of renewable energy generation technology around the globe. The most popular solar photovoltaic installation method is ground-mounted solar PV systems, which have currently encountered several practical limitations with increasing installation capacity. As a possible alternative, floating solar PV systems or floa-tovoltaics offer a promising solution by utilising water bodies' surface space and also taking advantage of the cooling effect, reducing land occupancy, preventing biological fouling, and also reducing the evaporating effect of water bodies. This paper presents an experimental performance analysis of floating solar photovoltaic systems in tropical regions, based on the results obtained through a pilot floating solar power system in Belihuloya, Sri Lanka. The primary objective of this study is to compare the performance of floating PV systems against ground-mounted solar systems, evaluate their efficiency, and identify other influencing parameters for system performance. Two identical test setups were utilised, each using a polycrystalline panel mounted on modular rafts for the floating system and ground-mounted units. Data collected under varied conditions was used to analyse the impact of these conditions on the efficiency of solar PV systems. This research aims to contribute insights into enhancing solar power generation efficiency in tropical contexts, particularly in Sri Lanka. The results of the study show that the floating solar system was able to gain 2.06% enhanced power output over ground-mounted PV systems. The performance ratio of the floating solar PV system was higher (89.60%) compared to the ground-mounted system (87.79%). Which shows floating solar PV systems are more productive and effective in tropical countries like Sri Lanka. The results obtained in this study conclude that floating solar systems are more sustainable compared to ground-mounted solar systems in the Sri Lankan context.

... Solar PV systems work by directly converting sunlight into electrical power using semiconductor materials and there are several parameters that affect the efficiency of solar PV panels such as solar irradiation, ambient temperature, wind speed, type of solar PV installation, etc [1] [2]. PV solar panels can be installed in many ways such as fixed ground mounted, fixed rooftop mounted, ground mounted with solar tracking system, floating solar system, building integrated solar PV systems, etc [3]. The fixed solar photovoltaic systems, installed at a set angle, typically face north in the southern hemisphere and south in the northern hemisphere. ...
