Until all of fossil fuel demand is displaced, solar will not be cheap enough for desalination. After that point, it will be reasonable, but we are years away from that. We should make farmers not hosting dual-use solar on their fields subsidize farmers who do. (Dual-use generates power, and also increased ag yield, reduced water loss, and more PV efficiency.)
