Solar is said to be the cheapest form of power generation by the dimwitted who forget to factor in that it can only provide about 6-8 hours a day of meaningful energy generation.
Ergo, it’s nothing more than a gimmick when we are talking about supplying a meaningful amount of power to anything other than a few days camping in the bush or running some low watt security light’s .
There are certainly no substantial industries that can rely on solar.
