All my wife's family lives in LA, and I'm always surprised at how unaffected they appear with living expenses there. They will comment, but that's about it. My brother-in-law has solar on his house, but he bought it that way. I asked him how big the system is, he didn't know. None of my other in-laws have solar, even though some of their homes appear to be ideally suited to an array. And it's not just electricity that's prohibitively expensive there, it seems to me. Taxes, water, even fuel for heat can be costly, because most homes are pretty poorly insulated.
I'm surprised I don't see more solar on homes when I visit, but given what I hear at family gatherings, not that surprised.
