What I mean is that a solar panel of any given size will produce electricity that can be used to desalinate an order of magnitude more water than a device like this of the same size. The device in this article desalinated 5.8 liters per square meter per hour in full sun, which means this 10x10cm device actually desalinated 58ml of water in an hour. A 10x10cm solar panel would produce enough electricity in an hour in full sun to desalinate approximately 600ml of water using reverse osmosis. A solar panel that was 1 square meter would generate enough electricity to desalinate about 60 liters of water in an hour in full sun.
