The payback period is ~10 years not 20.
That's not what our co-op said. I think the earliest they came up with for ROI was like 17 years. We would've mounted them on the roof, and I think we were looking at a 15-20kw system. And the more I think about it, the more I would NOT mount them on the roof, given how heavy the main house is (ICF block, and it's 3 stories). The other problem is usage. I haven't looked at our bill in a while, but it's usually in the $300-500/mo range. That's also for 2 houses and water well/pressure pumps. I do now that if I were to get an EV, I'd need a new line of service from the co-op, because I'm tapped out on electrical capacity,
And if you DIY it can be as little as 4. Signature Solar in Sulphur springs,TX just sold a batch of panels for $0.20/w. You could build a complete 10kW system for ~$7k. Saving you ~$1600/yr.
You're a lot closer to major populations centers than I am. You have a DC Fast charger ~30 minutes away. The closest for me >2x that far. Lots more coming.
True, but you're still close to Midland, which to me, is a BIG city. Outside of San Antonio, our biggest is Kerrville. Midland has to have some DC fast chargers. But even so, I contacted Telsa a few years ago, and they couldn't give me any answers as far as what kind of range I'd get when towing, what weight limit I could tow at, and how fast. They mentioned something about 55mph and I had to remind them that I'm in Texas, not California.
Somehow, I'm thinking this still belongs in another thread, since this thread is about fuel prices, not the ROI period for installing solar.
