Performance Analysis of Offshore Floating PV Systems in Isolated Area

The PV solar system is one of the most popular renewable energy systems. Besides being easy to apply, the infrastructure is usually more flexible than other power plants and the resources can be found almost anywhere. Along with the increasingly frequent use of PV power plants in isolated areas, there are obstacles to land use, especially in island areas, where land has been used for housing and community activity areas, so that there is no location left for PV power plants placement. Therefore, the PV power plant is installed above the water surface, known as offshore floating PV. Offshore floating PV and conventional land PV have different ecosystems, so there will be differences in performance. The performance of the power system is one aspect of choosing which system is best to apply. In this research, the indicators of the performance of the power system are voltage, current, and power output. They will be compared between offshore floating PV and conventional PV on land. The research location is the Kudingarenglompo island, which is an island located off the coast of Makassar, South Sulawesi, Indonesia. 400kW is provided as system capacity, which is based on the existing power system on the island. The research results show that current and voltage on offshore floating PV are higher than conventional PV on land, so the power output from offshore floating PV is higher than on land PV. The average power output on land PV is 1,29% lower than on offshore floating PV.
