Energy Output Simulation of the Floating PV System of Karangkates Hydropower Dam in East Java, Indonesia

Abstract

The Floating Photovoltaic (FPV) is expected one of the appropriate solutions for the expansion of the solar energy sector. This paper studies the possibility of implementing the FPV system in an existing dam in Karangkates, Malang District, East Java, Indonesia. The possibility of implementation is studied by simulating the energy output of PV systems using Solar GIS Pvplanner. The water surface area of the dam was found around 10,500,000 $\text{m}^{2}$. By considering 50% of the total area would be used for FPV system, about 560 MWp capacity solar panels would be possible to be installed. The annual energy production by FPV system would be around 721.2 GWh. The FPV system can be hybridized with the existing hydropower plant in Karangkates dam.
