6 FAQs about [Can photovoltaic panels reduce water evaporation ]

Do solar PV panels reduce evaporation losses?

We calculated the annual avoided evaporation flux using the Penman annual mean evaporation estimates (Fig. 3a) and assumed that shading the canals with solar PV panels would reduce evaporation losses by 78.5% ± 11.5%. We assumed the shaded area was equivalent to the total module area of 6,126.6 m 2 for a 1 MW installation.

Does water cooling affect PV panels?

The impact of the cooling effect of the water on the PV panel depends on the FPV design and float structures as well as ambient conditions, e.g., wind speed; nevertheless, regardless of the design, the FPVs have a lower temperature compared with the common solar farms (Kamuyu et al., 2018; Suh et al., 2019).

Can solar panels be placed over water ponds?

Placing solar PV panels over water ponds using, for example, floating solar systems not only conserves water by reducing evaporation losses through effects on incident solar radiation and surface wind speed, but enhances the energy yield (hence economics) of the PV systems through the cooling effect .

Should solar panels be placed over water bodies?

Placing solar PV panels over water bodies (using, for example, floating panels or water-body-spanning infrastructure) conserves water by reducing evaporation losses through effects on incident solar radiation and surface wind speeds 7, 8, 9, 10, 11, 12, 13.

How do PV panels affect water quality?

Large areas of PV panels cast shadows on the water surface and thus can reduce light availability to waterbodies, and floating materials on the water surface reduce contact between the air and waterbody, which may lead to reductions in water temperature and dissolved oxygen 17, 18. These changes might impact aquatic organisms.

Do PV systems conserve water?

Such systems do not only conserve water by reducing evaporation losses but results in enhancement of the energy yield (hence economics) of the deployed PV systems. As indicated earlier, in developing countries 90% of irrigation use water from such reservoirs, some of these are in remote off-grid regions.
