Well, if solar is going to get much cheaper -- which is a prediction CR plans to make real -- then electricity will get cheaper, because we'll take coal plans offline and put up local solar. We would be crazy not to.

However, I still need to grasp your numbers. A person paying $200/month at 10.5 cents/kwh is using 22,600 kwh/year. That requires something like a 12kw peak system (or more) in Mass. So you're suggesting you can put in a 12kw system for $15,000? That's such a major step over today's prices. Now you're selling it, so it must be true, I just remain amazed that vertical integration could make that happen.

Or are the $200/month customer and the $15,000 system two different examples? How heavy of a user is the $15K system meant to support?
