Floating photovoltaic (FPV) systems on reservoirs are advantageous over traditional ground-mounted solar systems in terms of land conservation, efficiency improvement and water loss reduction.. Here, we quantify FPV impacts on lake water temperature, energy budget and thermal stratification of a lake through measurements of near-surface lateral wind flow, irradiance, air and water. . The idea behind FPVs is simple; an array or combined arrays of PV panels are placed on floating structures that keep them above the water surface (Spencer et al., 2019). Such floating infrastructures are susceptible to a range of environmental risks that could jeopardize the long-term performance of these solar farms.. We found that water-surface photovoltaic systems decreased water temperature, dissolved oxygen saturation and uncovered area of the water surface, which caused a reduction in plankton. . FPVs probably exert a dual influence on evaporation rates. First, they create a shading effect, decreasing water surface temperature and consequently suppressing the vapour pressure gradient at.
