Around here, solar installation outfits come and go like the seasons. I would sure be concerned about depending on them a few years down the road. Same goes for much of the components.

And we have geo-thermal. We are not unhappy with it, but in our climate zone, I don't see how on earth it really makes any financial sense. It is just too expensive to install and any service is also much more expensive.

We would have already installed solar here, but the financial deal with the utility is just plain horrendous. The 2 deal breakers for me is that if the utility power is down, then we are down. And during the summer, typically you produce more power that you consume. That power goes into the grid and you get a credit. But the credit disappears at the end of the calendar year. So you end up giving them your excess power in the summer and then they get to sell you their power in the winter.
