Permit Power reports U.S. rooftop solar costs average $28,000 for a 7 kW system, compared with $4,000 in Australia and $10,000 in Germany.
The report says reducing permitting barriers could add about 20 million U.S. households installing solar by 2040, saving $1,600 annually.
Currently, 2.5% of American homes have solar, versus Australia’s more than 33%.
The proposal calls for instant permitting and remote inspections to reduce costs and expand access.
