Quote from Cache Landing:
Probably, but solar is viable as a long term energy source. We just put solar up at our cabin and it works great. Still too expensive to justify for the average home, but getting there.
It depends. The ROI is on avg 7 years that I have seen. I would consider it, but I am not planning on living in my current residence for that amount of time, but who knows right?
Supposedly in part of Denver Metro between the major power company Xcel and the fed rebates you can get the ROI down to 1 year! Unfortunately, I don't live in that area.
