The program tracking system is a method that the inclination angle of PV panel array and the panel direction are changed according to information about solar position input in advance.
Even though its cost is higher than other civil engineering materials, it is the most effective materials because the floating type PV energy generation system will be installed and maintained at the water surface which is highly corrosive wet environment.
