A Novel Accelerated Aging Test for Floats in a Floating Photovoltaic System
Countries around the globe have recently been actively developing a new type of solar power system known as the floating photovoltaic (FPV) system. The FPV system is advantageous in terms of efficiency and is economic; however, the environmental conditions on the surface of water are harsher than on...

Countries around the globe have recently been actively developing a new type of solar power system known as the floating photovoltaic (FPV) system.
