I think the problem is likely exactly what you describe, the high cost for most people to install the panels. For some reason people treat roofs like black magic, and in some ways I can see that from a contractor perspective. Since I’m looking at this from a different perspective (in house labor, we also do our own construction) for us it’s an absolute no-brainier. A 660watt panel which cost us $125 produces $200 of electricity in its first year of operation at local rates.after installation and support infrastructure our installed per panel cost is around $400, so on the third year we are cash positive. I acknowledge that it’s not the same for many people, but this seems like it is in the same category as the fact that I can get an MRI from the exact same machine here for $150 (in an unsubsidised, for profit commercial imaging center) while the (imaging only) cost is $2700 in the USA for the same study. It seems like somebody is getting screwed.
