I have begun the first stages of my solar cabin build. You can follow
the adventures at http://www.solardiy.info
There are also tons of links to reference info for anyone interested
in undertaking any project related to solar energy, be it solar
heating, electricity generation, or water heating.
Since the site has turned into mostly a blog about what is happening,
I have also been adding news articles relevant to solar energy that
I've come across on the internet.
Feel free to send me an email if you have any questions or feedback
