Here are some links to sites about solar power with varying levels of
relevance to each other and the real world. Actually a lot of the
links are not even about solar power but at some point they seemed
worth keeping, so it's just possible somebody else may find them
useful. They are all working at the time of posting, although I had to
throw a few out of the longer list I had before.
There's a slim chance that somebody who reads this may find one of
these sites interesting, and I'm not sure whether to press the send
button, or delete.
