This literature review is on the Floating Photovoltaic system. Floating Photovoltaic also known as floating solar is a solar power system that is mounted on a structure that floats on water(Lake, River, reservoir, etc..). Floating Photovoltaic systems generate 18% more electricity than ground-based solar systems due to the cooling effects of the water. Water temperature has a crucial effect on the efficiency of the solar FPV systems, it is imperative to monitor and gather data on the temperature of the water. FPV can solve water evaporation crises and also provide greater efficiency in power generation at the same time. Higher efficiency can be gained from the FPV if the water temperature is between 25 to 35 degrees Celcius. It can also save 60% of the water evaporation by just covering 40% of the water surface area with solar PV systems.
