In this paper, we present the result of investigations pertaining to the development of links between unit modules of the floating type photovoltaic energy generation system made of Pultruded FRP. Since the FRP has an excellent corrosion-resistance and high specific strength and stiffness, the FRP material may be highly appreciated for the development of the floating type photovoltaic energy generation system. we discussed the development concepts of the link between unit module of floating type photovoltaic energy generation system made of PFRP, tire, and synthetic fiber, briefly. The floating type photovoltaic energy generation system linked between unit modules is installed successfully at sea site.
