Well, not in California where there is both a residential solar mandate assuring new distributed supply and where solar already reaches over 100% of demand at peak; adding new utility-scale solar doesn't make a lot of sense even if it is cheap.
Politics and corruption. The generation cost is low, but the government backed monopoly folds all kinds of distribution, deferred maintenance, fire damage, and political pet projects into the retail price. It sucks.
According to the article Trump is trying to ban new solar developments. Suppliers are building tons of solar but they can't do so if the government makes it illegal.
