The US community solar market surpassed 10 GWdc of installed capacity in late 2025, despite a 25% contraction due to slow growth in states like New York and Maine.
Why it matters: The US hit 10GW by treating solar as a financial asset; until EU regs stop treating it as a grid threat, community projects remain hobbyist ventures.
The Grass Is Always Greener (And Better Subsidized)
So, the US hit 10GW in community solar. Before you start drafting a business plan to export your installation team across the Atlantic, let’s look at why this number is a massive indictment of the European market, not a template for it.
In the US, 'Community Solar' is a distinct financial product: a mechanism to monetize the tax equity of institutional investors while providing utility bill credits to residential customers who can't put panels on their own roofs. In Europe, we have 'Energy Communities' under the RED II/III directives, but they are often bogged down in bureaucratic grid-connection requirements and national-level protectionism.
Why the US Model Actually Moves
Contrast this with the EU. If you want to replicate this success, you aren't fighting for solar tech—you are fighting for the Renewable Energy Directive (RED III) transposition in your specific country. Currently, most European 'community' projects are glorified pilot schemes with high O&M costs per kilowatt-hour because we lack the centralized, standardized off-take agreements that keep the US market growing despite a 25% contraction.
The takeaway: Don't envy the 10GW number. Envy the regulatory framework that allows a developer to treat a solar array as a financial asset accessible to the public. Until your local energy regulator stops treating 'prosumerism' like a threat to the DSO balance sheet, your community solar project will remain a boutique hobby, not a business.
