A local woman got solar collectors installed on her roof a few months ago. Every month she posts that her electric bill is zero. She never post how much she pays every month for that installation, though. Substituting one bill for another is not my goal in life. How much will repairs cost when something goes wrong with her system?
Another question. How much will it cost to replace the roof when it's time. The panels will have to be removed and replaced when the roof is done. I'm willing to bet when the roof is done, they will probably tell you that they are no longer efficient and need to be replaced. Another cost. If you have storage batteries, you need to check out the cost of replacing those.
