Great concept. But be careful when you are checking out their payback calculations.

I checked into solar power over 10 years ago when we were building our house & I think the 8 year payback is hogwash. What the company I was looking at was leaving out was the interest you would be paying on all the extra money that you would have to borrow.

At the time the mortgage rate was at 8% & you take that times the solar setup of $30,000 which would be $200 a month in INTEREST alone. Our electric bill has never been over $125 so you would never reach a payback date. Even if the system worked flawlessly.

Interest rates are lower now so lets take current mortgage of 6% X $13,000 = $65 a month just on the interest.

This system would have a huge advantage over a solar electric alone because you would also be slashing your heating & electric bill at the same time.

After reading the article it would also be better than the solar one because it would replace the initial cost of a furnance which they said is roughly 1/2 of their system. If that's true you would only be paying off the $6,750 difference.

I'm very interested in this system. THANKS FOR THE POST.
