There’s generally subsurface water available that merely needs filtering and/or treatment. Electric pumps and filtering systems can run off solar power too, y’know, and the yield will always exceed these kinds of gee-whiz things.
These pie-in-the-sky doodads are generally peddled as a way to end the supposed privatization of water by, you guessed it, Big Corporations.

This is the way....

Here is the USGS map of the massive brackish aquifers under the USA. Remember most of the USA was under an ocean multiple times in the last few hundred million years those sediments are still fully saturated with salt water.

You could also put panels up over long rows of fish troughs and use the reject brine which is as salty as seawater to grow saltwater fish and shrimp and lobsters. The panels power the desal and pumps you control the process via voltage to output seawater reject brine from the brackish input going from 10000ppm to <500 on your fresh output and 30,000ppm on your reject a 3:1 recovery ratio. From the fish troughs you pull water out of them as they exceed 35,000ppm and send that to a rapid spray desal process that recovers 98% of the water as fresh and 2% is lost with the solid salt product which is then sold as road salts or landfilled with say all those trees from the billion tree project. The salt locks the carbon up since it essentially turns the wood to petrified wood in clay lined landfill. Shame to waste all that lumber though better to just landfill the salt by itself.
The end products are tons of fresh water, lots of yummy redfish or snapper with some shrimp and lobsters on the side. You could also grow saltwater microalgae in those troughs with yields of starch,lipids or both at ten times or more what the very beat land plants the agaves could do. Here again massive amounts of food or biofuels. Water plus sun = lots of good things.
