There are solar thermal systems that are reasonably simple to install. I'm sure there are lots of websites where one can learn to do it, get a parts list, etc. Solar electric panels generally require knowledge of the electrical code and would be best left to a licensed electrician or certified solar installer. In either case, you might not be eligible for federal or state incentive funds if you DIY, but that would be something to check into.

Great Design! Would love to see the performance and heating demand in the winter in Maine. Please check out the drainback Secusol solar thermal system. Perfect for Passiv Homes http://usa.wagner-solar.com/heat/products/solar-heating-systems/hot-water-systems/secusol-hot-water-system.html
