State policy design dictates U.S. community solar growth as national contraction takes hold

Community solar lets you buy into a shared solar project and get credits on your electric bill, without installing panels on your own roof. New data shows this market is growing fast in only a few states, while most of the country has slowed down due to permitting delays, grid connection backlogs, and weaker program rules. For the third quarter in a row, New York, New Jersey, and Oregon were the only states where community solar capacity grew by more than 1%. Maine, once a strong market, has cooled off after lawmakers scaled back its billing program.

The states that keep growing share a few features: they require projects to be owned by independent companies rather than utilities, they guarantee subscribers a real discount on their power bills, and they lock in payment rates for 20 to 25 years so projects can get financed. New York's program guarantees at least 5% bill savings and offers extra discounts for lower-income households. New Jersey requires more than half of each project's capacity go to low- and moderate-income subscribers, with a minimum 15% bill discount. Oregon locks in fixed credit rates for 20 years and reserves part of each project for low-income households. Massachusetts folds community solar into its broader solar incentive program, guaranteeing 20% savings for regular subscribers and 40% for low-income ones.

If you're weighing whether community solar is available where you live, this is worth checking with your state's energy office or utility commission, since access, savings, and rules vary widely depending on where these stronger protections exist.
