US Community Solar Hits 10 GW Milestone

Community solar in the United States just reached 10.1 gigawatts of capacity, a milestone that marks real progress for people who want clean energy but can't install rooftop panels. The model lets customers subscribe to shared local solar projects and receive credits on their electricity bills, making renewable energy accessible to renters, apartment dwellers, and anyone without a suitable roof.

New data from Wood Mackenzie and the Coalition for Community Solar Access shows the sector has delivered bill savings to thousands of households and businesses across the country. These projects don't require homeowners to make massive upfront investments or own property at all.

Growth hit a speed bump in 2025, with installations dropping 25% compared to the previous year as mature markets like New York and Maine slowed down. The US added 1,435 megawatts of community solar last year, below expectations.

Forecasters expect a 12% rebound in 2026, driven by expansion in Illinois and Mid-Atlantic states. Developers are sitting on more than 8 gigawatts of projects in the pipeline, with 29% already under construction.

The real story is how the industry is adapting. Developers are now focusing on smaller "community-scale" projects up to 20 megawatts that can connect directly to local grids and get built faster than massive utility-scale solar farms.

New state programs in Ohio, Iowa, Pennsylvania, and Michigan could unlock 1.5 gigawatts of additional capacity through 2030. These emerging markets represent the next wave of growth as the sector matures.

The Bright Side

Customer costs are heading in the right direction. Subscriber acquisition costs dropped 12% in 2025, making it cheaper for developers to sign up new customers.

Wood Mackenzie expects those costs to keep falling through 2030 thanks to consolidated utility billing and better digital marketing tools. Lower customer acquisition costs mean more savings can flow to subscribers.

Developers are also getting creative about reaching underserved communities. While low and moderate income customers still cost the most to sign up at around $100 per kilowatt, companies are testing new approaches to make community solar accessible to everyone.

The sector faces real challenges, including interconnection delays and changing federal tax credit rules. But the fundamentals remain strong: people want clean energy, and community solar delivers it without the barriers of traditional rooftop installation.

Ten gigawatts represents thousands of projects serving communities across America, proving that shared renewable energy works at scale.
