I have some friends that are house shopping and they found a really interesting home with many normal aspects except that it also has solar electric. They were told (unknown source) that they might have problems with bank financing because of this. I also have some other friend who recently built a house and were looking into alternative power ideas, but again, the banks would not back these options. Does anyone have experience with this? Is it true, is it only a US thing? Any theories as to why they won't promote alternative power? Note: I'm not trying to start a debate about benefits of energy source X vs Y, just trying to find out if these cases are the norm.
