I was speaking of this system. I know how my batteries last, so I am skeptical of this paying for itself. Insulation?? how do you get from batteries to insulation (a proven technology, btw)? That is a big leap.
Then I guess you are not interested in upgrading your homes insulation? Or anything else in your house. To limit yourself to a 1 year return for systems with lifetimes measured in decades is a bit silly.
