I wish those of you who have had solar installed would give those of us who are considering it a bit more information. such data as size (KW), cost, ROI, rebates and such, and what part of the country you live in. Knowing whether you live in Arizona or Seattle, for example, would help us put things in perspective. I'd be grateful.
Taking on a major remodel of a 50's modern house. Looking at PV panels for 3 carports and the roof of a guest casita. ROI is saying breakeven at 6 1/2 years for lower voltage model, about 10 for higher one. We're in S. Texas. We would save a little more because for the carports, the panels are actually part of the roof structure. Freedom Solar Power: 12.19 kw, 814 sf, annual production estimate 17,712. $48k-$21k utility rebate-$14.6k federal tax credit=$13k. 15.04kw, annual 21,856. $75k-$25k utility rebate-$22,5 federal=$27,6kLooks like the second one hits up against rebate limits, so breakeven is estimated to be 4 years later. At 20 years, you're only $7k ahead, so it seems to make more sense to go with the 12kw proposal. Does that make sense?
