You will probably find the best information online at how to build solar panels and wind turbines .
We found this site after searching for a good guide for diy solar and wind power. It's quite personal and caters for those of us with very little diy experience.
Videos and diagrams demonstrate how to build your own solar panel and wind turbine energy system for less than $200! Considering our original quote for home solar power installation ($26 000) we were extremely happy to give it a shot.
Our thinking was that we wanted to keep our original investment to an absolute bare minimum - the most common complaint about home solar power is that the outlay is just too much and people only see the return on their investment way too far in the future. We wanted to see some returns ASAP.
A nice surprise is that the site also has help available for applying for financial rebates to the United States Department of Energy - for investments in renewable energy, and of course diy solar panels and wind turbine power.
Hope that helps, good luck and have fun, we are. We begun with the solar panel (we have finished 2 solar cells) and are almost finished the wind generator.
