One aspect of solar power that gets little discussion is the effect of cleanliness.
A dirt film on the collector rapidly degrades performance. Which means somebody has to clean the darn things on a very regular basis. Somebody who will want to be paid for his work.
Probably another job Americans won'd do.
Good point, but some types of solar materials can convert a wide range of frequencies, which gets mostly around the dirt problem. There are also coatings like titanium dioxide that can chemically break down dirt using nothing more than sunlight.
