Out of all the DIY green energy guides we have tested, Earth4Energy is the best. What really makes it stand out is the amazing video series it comes with and the high quality, fully-illustrated instruction guide. You will be able to get most of the parts at your local hardware store and have your system up and running over a single weekend. If you do run into any issues, their customer support is extremely helpful and responsive. It is also worth mentioning that you get free updates for life with nothing more to pay.
