"The proposed Al Khafji desalination plant in Saudi Arabia is planned to provide 60,000[1] cubic meters per day powered by a nearby 15-megawatt solar power generation plant."

"It takes approx. 2.6MJ to evaporate 1kg of water from 15 degrees c. 1kWh is 3,600kJ, so say solar day is defined as 8 hours for energy gathering purposes and we take a year as 365 days we get 3,600kJ x 8 hrs x 365 days = 10,512MJ, enough for 4,043, say 4000kg of water (4000 litres). All on the assumption that the 1kWh is net input energy, not incident solar energy."
