I went through this same drill back in the late '70s, when Carter was pushing his solar ideas and you got up to a 50% tax credit for putting one of these things in. Plus, in my state, you got another 10% on your state income taxes. I looked at them all, PV, hot water heating, space heating, the whole smash. The answer was always the same: I'd be dead before I saw any kind of real savings.
The numbers always turned out that I could buy a lot more kwhrs and BTUs from the local utility than I could ever save using these things. I just couldn't afford the economic penalty. I know a lot of people get warm and fuzzy feelings from doing these kind of things but in my case it just didn't make sense. I had college tuition to save for and young children to clothe and feed.
One thing people often overlook in the cost analysis is the time value of money. Would I be better tying up capital and interest charges on financing purchase of a solar heating system, or would I be better off buying CDs and other investment instruments that would earn me interest on my money? Kind of a no-brainer.
