I think this fits into the OTHER category...
I just installed solar panels on my roof... 26 panels - should produce 7.41kw
I have an all electric home with no gas onsite... so either I go propane or heat pump for pool heat ... haven't done either yet, but did install these babies.
I am hoping to be able to run my pool pumps (2) and my house. I am waiting on the power company to come install my new panel and meter so I can turn them on, but in a test run, at 8 in the morning they were producing enough energy to run my house with the A/C on (I did just put a new A/C unit on 15 seer Maytag, and switched over to all LED lights in my house). I am also going to a Hybrid water heater for the house as well, to cut my footprint down even further. The goal is eventually to the power company pay me, rather than I pay them..
The company that did them for me in Vegas is awesome. And I own these outright and get a 30% federal tax credit. The only way to go (i.e. In my opinion, I would never lease btw, I'd be happy to talk to you about that offline).
