http://www.homepower.com This is a magazine filled with examples of people building solar-powered systems and homes. It's especially nice that they let you read every issue on the net for free! Some of the ads are even valuable and informative. They describe things like solar-powered air conditioners, 12VDC refridgerators, and more. Most articles include analysis describing how long before solar setups pay for themselves (typically 7 years for a ~20KW home system!). There's sometimes even a section by anonymous people who are using solar power *illegally*. heh heh heh
http://www.solarseller.com Owner John Drake very friendly. Talked to me for quite a while and gave me good information. Get a Steca 8 Amp charge controller there for $37.50 while he still has his surplus! I used one for a week in the desert at Burning Man and was satisfied (web page about that whole experience pending). His website also has a large number of DC appliances. You get more

Price/Size Comparison Graph I used the current prices at www.partsonsale.com. You can see that the 84, 212 and 258 Amp hour batteries have the most bang for the buck. Avoid the 49 and 108!

Expect to pay $4 per watt for photovoltaic panels.
A human being can be reliably expected to generate 100-150W of power on a bicycle for several hours before exhaustion.

Interactive Solar Radiation Map (sorry, US only...) Use these to estimate how much energy you can generate with solar electricity.

An unexpected discovery could yield a full spectrum solar cell This is REALLY good news. It means solar cell efficiency will soon DOUBLE...and to think they were just trying to design orange LED's....:)
