In this area the water seems like the least renewable resource / more of a short term concern:
“So much water is now being used that ground water levels in Helmand are estimated to be falling by 3m a year.
The fear is that pretty soon the water will simply run out.
"Maybe this boom will not last longer than 10 years," says Orzala Nemat.”
Home solar panels seem to typically come with guarantees of ~80% capacity up to 20-25 years. I think they need cleaning for peak performance, but that doesn't seem important in this use case.
