From another blog I ran across (see here), more reasons to go for solar hot water, which is even more economical than solar electricity. If you want to get going in that solar direction, solar hot water is an easy way to do it.
The above blog also mentioned a website which looks like its got good info on how solar works practically, for electricity and water: WaterHeating at builditsolar.com
