QuoteIn some areas, such as California, Florida, the mid-Atlantic, the Midwest, Texas and the Southwest, small increases in solar were estimated to deliver large CO2 reductions, while in others, such as New England, the central U.S., and Tennessee, impacts were found to be minimal

I'm always surprised how much residential solar I see in Vermont and how little I see in Texas. You would think it would be the reverse.

The incentives are basically the same - no property tax on the added value created by adding solar panels.
