The PV solar system is one of the most popular renewable energy systems. The use of PV system has increased in recent years from urban areas to cover remote areas or isolated areas. Along with the increasingly frequent use of PV power plants, 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. 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 system output, availability factor and economic feasibility. The research location is the Kodingarenglompo island, which is an island located off the coast of Makassar, South Sulawesi, Indonesia. 3MW is provided as system capacity, which is based on the existing PV power system on the island. The system output for both type of PV system calculated and simulated using Matlab Simulink and copared the output. Availability factor analyst shown how the influence of the intermittent from solar radiation affects the output power of the offshore floating PV power system. LCoE analyst using power output from simulation and total cost for PV system obtained from NREL Benchmark Cost for Floating PV.The research results show that output on offshore floating PV are higher than conventional PV on land. Availability factor on the Offshore Floating PV shows the instability of the output power, especially in the rainy season caused by the high cloud opacity, so that the solar radiation reaching the solar panel surface is also reduced. Result of LCoE for the Offshore Floating PV lower than conventional Land PV where the value of LCoE for the Offshore Floating PV lower and conventional Land PV more expensive than electricity price standar in Indoenseia, especially in Kodingareng Island.
