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.

Are solar panels on water canals a good idea?

Solar panels on water canals seem like a no-brainer. So why aren't they widespread? One study estimates that covering California's canals with solar panels could generate enough energy to power Los Angeles for most of the year. Back in 2015, California's dry earth was crunching under a fourth year of drought.

Why do photovoltaic panels require water?

Photovoltaic panels do not strictly need water, but the water environment is conducive to the cleaning of the photovoltaic panel. This helps alleviate the impact of dust fall on the panels. However, a high temperature and humidity in the water area can increase the attenuation rate of the photovoltaic modules and the installation and operation costs.

Can photovoltaic panels be installed on artificial water bodies?

Photovoltaic panels can be installed on 2% of the surface area of artificial water bodies according to one study, which would result in a total installed capacity of 16 GWp. The National Renewable Energy Laboratory assessed the technical potential of WSPV systems on artificial water bodies in the USA in 2018.

Can solar panels save water?

The idea is simple: install solar panels over canals in sunny, water-scarce regions where they reduce evaporation and make electricity. A study by the University of California, Merced gives a boost to the idea, estimating that 63 billion gallons of water could be saved by covering California’s 4,000 miles of canals.

How will solar panels affect water quality?

About 2.6 kilometres of canals between 20 and 110 feet wide will be covered with solar panels between five and 15 feet off the ground. The UC Merced team will study impacts ranging from evaporation to water quality, said Brandi McKuin, lead researcher on the study.
