Calculating the energy capacity and capacity factor of floating photovoltaic (FPV) power plant in the cirata reservoir using different types of solar panels

The trend to use solar energy as an electrical energy source continues to grow around the world. Located on the equator, Indonesia has the potential for continuously available solar energy throughout the year, which means that the use of solar energy as a solar power plant need to be increased. Floating solar power plant is a solution for solar power plant development in areas where land is limited due to high population density. One of the reservoirs currently under development and construction of floating solar power plant under the Electric Power Supply Business Plan 2021 - 2030 is the Cirata Reservoir with power capacity of 145 MWp. This study aims to obtain the results of the calculation of the energy capacity and capacity factor of the 145 MWp Cirata Reservoir floating solar power plant using different types of solar panel with RETScreen Expert software. This study uses data analysis techniques. The annual energy capacity results for monocrystalline, polycrystaline, and thin-film solar cell module types are 190.54 GWh, 190.54 GWh, and 186.87 GWh respectively. The capacity factor results for monocrystalline, polycrystaline, and thin-film solar cell module types respectively are 15.00%; 15.00%; and 14.70%.
