For people like me that use less than 600kwh / month or 20kwh/day just about anywhere in the US works as long as you are not in an apartment. In the northern US you will want a solar hot water heater, but that's got a 2-5 year ROI.

Granted, my electric would only be 50-60$ a month so the savings is also not huge, but that still adds up to 9-11k in 15 years and panels last well past that.

PS: Solar quietly got really cheap, installation is often one of the major costs.
