Solar power may not be the most economical for large scale water desalination for the moment. However the exciting thing is that small to medium size solar water desalination plant are already an economical solution in many places in the world: https://sinovoltaics.com/technology/solar-water-desalination-decentralize...
A decentralized approach can be cost effective as you don't need to establish a complete 'water infrastructure' when unavailable.
