Abstract: Solar power is clean energy, with investment costs decreasing over time thanks to the development of photovoltaic (PV) panel manufacturing technology. Solar power requires area to accommodate panels exposed to sunlight; panels placed on the ground often occupy large land areas and are considered difficult for solar power investment development due to land clearance costs and local land availability. To save space, investors have studied utilizing hydropower reservoirs, irrigation lakes, lagoons, and estuaries to place floating panels on water surfaces. Another advantage is that placing panels on water yields higher efficiency than on land due to evaporative cooling. Challenges when placing panels on water include the durability of floating materials, the tilt angle of PV panels, and water level fluctuations.
