We have ion solar. Works well, but we are also energy conscious (cheap skates) so we have always kept our energy low. We dont crank the AC and only have lights on we are actively using. Our power bill is effectively zero and we actually bank quite a bit if power. But they buy it back for pennies on the dollar at the end of the year so doesnt mean much. Theres always a flat power fee just to be hooked up. Ours is like $15. If batteries were more affordable (they're improving a lot) then I would like solar even more since we could store the power for weather and such. As it is now its kind of a bummer that we are predicting power to the system but if the power goes out we are still out.

It was worth it with the tax breaks. Without them I wouldnt do it. It will pay for itself in about 10 years with average cost increases for power, so anything after that is gravy. If batteries get down to the 3k range or so (currently around 8 to 10k) then I would get one and that would make it more worth it.
