Waste of money. Government dollars should go into the most cost effective green electricity, which is **utility scale** solar, or wind, depending on location. Not rooftop.
For $7 billion you could install 5-10 GW of utility scale solar at 20% capacity factor, phasing out 7 million tons of annual CO2 emissions. Same money spent on rooftop solar will get you 2-3 GW at 15% capacity factor, phasing out 1.7 million tons of annual CO2 emissions.
