WASHINGTON, D.C. — Surpassing a significant milestone, the United States has now exceeded five million solar installations, a five-fold increase since 2016. This achievement underscores the nation’s robust shift towards clean energy. Just eight years ago, the U.S. celebrated its one-millionth installation, a feat that had taken 40 years since the first grid-connected solar setup in 1973.
Since the start of 2020, a significant portion of U.S. solar installations, comprising more than half, have been completed. Additionally, over 25% of these installations have been added since the enactment of the Inflation Reduction Act 20 months ago. These installations are diverse, covering residences, businesses, and expansive ground-mounted arrays nationwide, as per the latest data from the Solar Energy Industries Association (SEIA) and Wood Mackenzie.
“Solar is expanding rapidly because it consistently delivers on its promise to lower electricity costs, enhance community resilience, and generate economic opportunities,” said Abigail Ross Hopper, president and CEO of SEIA. “Currently, 7% of U.S. homes have solar power, a number expected to grow to over 15% by 2030. Solar is rapidly becoming the predominant source of electricity, promoting cleaner air and healthier lives for communities.”
Despite shifts in state policies, market indicators suggest substantial growth nationwide. SEIA projects U.S. solar installations to double to 10 million by 2030 and triple to 15 million by 2034.
Residential installations account for 97% of total U.S. solar setups, setting annual records for five consecutive years and 10 of the last 12 years. Residential solar adoption is accelerating as homeowners recognize its value in managing energy costs.
Presently, 11 U.S. states and territories boast over 100,000 solar systems each. California leads with 2 million installations, yet recent policy shifts have affected its rooftop solar market. Meanwhile, states like Illinois and Florida are seeing rapid growth in solar adoption.
Looking ahead to 2030, projections indicate that 22 states or territories will exceed 100,000 solar installations, underscoring the broadening embrace of solar energy nationwide.
