Is it a good idea to build photovoltaic panels on the river

And because solar cells become less efficient as they heat up, the water’s cooling effect can increase their conversion ability by as much as 20 percent. Given the benefits, the sluggish pace of .

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.

The idea is simple: install solar panels over canals in sunny, water-scarce regions where they reduce evaporation and make electricity.

One approach to the challenges of the energy–water–food nexus is the use of solar photovoltaic (PV) panels to cover water bodies such as natural lakes, reservoirs, wastewater treatment basins.

“By covering canals with solar panels, we can reduce evaporation and avoid disturbing natural and working lands, while providing renewable energy and other co-benefits,” says environmental .

6 FAQs about [Is it a good idea to build photovoltaic panels on the river ]

Can solar panels save water?

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.

Can solar panels be installed over canals?

The idea is simple: install solar panels over canals in sunny, water-scarce regions where they reduce evaporation and make electricity.

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.

Can solar panels be installed on water reservoirs?

Insufficient power lines and access to canals for maintenance are possible barriers too. She was similarly cautious when I asked her about solar panels on water reservoirs, a question prompted by the recent news that two wastewater treatment ponds in Sonoma County are now home to the nation’s largest floating solar farm.

Should irrigation canals be shaded with solar panels?

Exhibit A is the idea of shading irrigation canals with solar panels for a planet-saving win-win-win. The cooling effect of the water improves solar conversion efficiency, the shade prevents excess water loss from evaporation, and the use of built infrastructure preserves land from development. What’s not to like?
