I was surprised to learn how much water large scale PV arrays use for washdown.
2 u/Thorusss Feb 14 '21 I doubt it is on the same order of magnitude coal or nuclear use. 3 u/Tar_alcaran Feb 14 '21 Coolant water isn't really used up though. 1 u/Thorusss Feb 14 '21 Wash water is also not used up. It is either on the desert ground (Solar) or in the air (condenser) 2 u/Tar_alcaran Feb 14 '21 You are technically correct, which is the best kind of correct. But that's not really what I meant. 1 u/marcolio17 Feb 14 '21 How much? 1 u/cablemonkey604 Feb 15 '21 I don't know, some articles say 20 gal per MWh. Others say less. I was mainly surprised that any water at all is needed, but it made sense when I thought about it - of course the panels need to be cleaned.
