Performance Analysis of Floating Photovoltaic Systems on the Water Surface

This paper introduced the results for 3-years study period, focusing on two floating photovoltaic test systems with capacities of 2.4 kW and 100 kW. These two systems were installed at two reservoirs in Korea's southern provinces. The results indicated a 10% increase in power generation due to the cooling effect on the PV modules resulting from the low temperature of the water surface. In addition, a mooring method was developed to ensure that the buoyancy body can adapt to large changes in the water level in the dam reservoirs while maintaining the direction of the body. Furthermore, the effects of applying water-proof systems and the challenges yet to be resolved are also described in this research.
