Recently, interests in renewable energy have gradually increased. Photovoltaic system of various
renewable energy is the most interest in power sources. Nowadays, the market of photovoltaic system
is expected to be expanded due to the introduction of RPS(Renewable Portfolio Standard). Floating
photovoltaic system is a new power system using the water surface above the dam and reservoir
water. Floating photovoltaic system is different from the traditional approach to the development of
solar power system causing problems such as environmental degradation. This paper investigates the
analysis methods of suitable site for the development of floating photovoltaic system. The A,B,C as the
optimal candidates were selected in hap cheon dam. The C is the best suitable site in A,B,C
considering the expected power generation. Applied methods have effectively done to develop floated
photovoltaic system.
