North Carolina proves that you don’t need to be in the Sunbelt to make solar work – sometimes smart policy and determination matter more than perfect weather.
Hawaii Leads in Solar Penetration Per Capita
Hawaii leads the nation in non-residential distributed generation, ranking first per capita, with 36% of homes in the Aloha State having solar, though the state’s residential solar is ranked 24th per capita, compared to California where 24% of homes have solar. As of the end of 2024, approximately 26% of HECO’s residential customers had installed solar panels, with penetration even higher among single-family homes at 43%. This means that nearly every other house you see in Hawaii neighborhoods has solar panels on the roof.
Hawaii leads the country for residential solar-plus-storage systems, with 96% of all residential rooftop solar installations in Hawaii including energy storage according to the legislature. With fantastic solar insolation and high electricity prices due to a dependence on imported energy, Hawaii is an ideal solar market, and with the highest electricity rates in the US, Hawai’i can use energy storage as a mechanism to significantly lower customer rates. When electricity costs more than almost anywhere else in America, solar becomes less of a luxury and more of a necessity.
Massachusetts Defies Geography with Solar Innovation
Massachusetts ranks fifth in solar installations per capita with 1,577.30 installations per 100,000 people. Renewables contributed almost 30% of Massachusetts’ electricity generation in 2021, mostly coming from solar energy sources, with small-scale solar PV systems making up nearly 66% of the state’s total solar capacity that year. The Bay State shows that cloudy winters don’t have to kill solar dreams. Massachusetts has been a leader in renewable energy adoption for years, with the state’s Solar Massachusetts Renewable Target (SMART) program providing incentives for residential solar installations, making it financially viable for homeowners, and Massachusetts also offers net metering and tax credits, further boosting solar adoption.
Massachusetts proves that innovation and policy can overcome natural disadvantages. When you drive through suburban Boston neighborhoods, you’ll notice something remarkable – solar panels have become as common as colonial shutters, showing how New England efficiency extends to energy production.
New Jersey Surprises as Northeast Solar Leader
New Jersey ranks sixth nationally with 1,415.68 solar installations per 100,000 people. New Jersey is a surprising contender in the residential solar market, thanks to its progressive energy policies and incentives, offering one of the most generous Solar Renewable Energy Certificate (SREC) programs in the country, allowing homeowners to earn credits for the energy their systems produce, and New Jersey also has strong net metering policies and various state incentives. The Garden State has quietly become a solar powerhouse, ranking among the top states despite its dense population and limited space.
New Jersey’s Successor Solar Incentive (SuSI) program provides substantial financial incentives, including payouts for generated solar energy, similar to how Massachusetts has a strong Solar Renewable Energy Credit (SREC) market that incentivizes solar production.
