I've been looking at adding solar to my house. I think about 6000-7000w worth of panels will offset my cost of purchasing from the power company. I would like to do the installation (roof installation, running wires, mounting hardware) myself and then have a licensed electrician "friend" come over and do the final wiring. It looks like ROI might be around 8 years, and I don't plan on moving so after that I can reap the rewards.
Has anyone here done something like this? Who did you purchase panels, inverters, and mounting kit from? Has your ROI been close to what was calculated?
