The ROI I calculated at our current rate of consumption was 19-22 years. The problem with our going solar is that our home is already under 30 years old, we have a brand new roof, < year old HVAC system, good windows, great insulation, all LED lighting, and all low consumption appliances. Basically, since the panel installer only finances enough generation to offset 80% of your current average use, the cost savings/offset was minimal and we'd only end up really saving about 4 months of the year so the juice wasn't worth the squeeze.
With that said, my one buddy literally makes money off of his system every month. He got quoted for solar not long after he bought his house. The home was 60+ years old with no updates and he only had about 6 months of bills to average off of. As soon as they did the install, he re-did his roof, windows, HVAC, etc and cut his consumption by something like 60%.
