This paper compares and analyzes the empirical data of the floating PV system, which K-water has installed, with that of the existing overland PV and has verified that the generating efficiency of floating PV system is superior by 11% and more. During analysis, data acquired when the floating PV system was rotated and moved by wind was not used. Research on a mooring system that can completely fix the buoyant structure of the floating PV system on the water surface is continually needed. Also, in

order to enlarge the generating efficiency, development of a solar-tracking floating PV system that can change its azimuth and tilt angles is required. Currently, K-water is researching and developing a 100kW solar-tracking floating PV system, which has superior generating efficiency compared to the stationary floating PV system, and it is expected that development of such system will open a new chapter in the solar-energy market. Also, 20kW marine floating PV system is being installed in order to analyze corrosion effect of seawater on module and PV structure and its relation with generation efficiency.
