Effects of water surface photovoltaic systems on the water

The shading area of the PV panels on water surfaces is the most suitable metric to measure the effects of WSPV systems. Waterbirds are highly dependent on wetlands for nesting, feeding, and resting (Wang et al., 2018) and thus are susceptible to wetland habitat changes by the introduction of WSPV systems. In the PV areas, we found decreased
