EU Solar Expansion Faces First Decline in a Decade

For the first time in over a decade, the European Union’s solar energy rollout is experiencing a year-on-year decline. According to the latest data from SolarPower Europe, the EU is expected to install 64.2 GW of new solar capacity in 2025, down 1.4% from the 65.1 GW installed in 2024. This marks a shift after years of consistent growth, including a sharp 51% rise in 2023.

The slowdown has been largely driven by a drop in residential rooftop solar installations, which are projected to contribute just 15% of new capacity in 2025-half the share seen between 2020 and 2023. This dip follows subsidy reductions in key markets like Germany, France, and the Netherlands, where governments have cut feed-in tariffs and incentives for households exporting surplus power back to the grid.

Though solar still made significant strides-accounting for 22% of the EU’s total electricity generation in June 2025-the pace of deployment is falling behind targets. Current projections show the EU will miss its 750 GW solar capacity goal for 2030 by approximately 27 GW, potentially hampering climate targets and energy independence ambitions, particularly in light of the EU’s ongoing strategy to phase out Russian energy sources.

The shift underscores a growing tension between clean energy goals and fiscal priorities, as European countries navigate rising defense spending and industrial support. While utility-scale solar projects continue to grow, the waning momentum in residential adoption signals the need for renewed policy focus if the EU is to stay on track with its green transition.

A first-in-a-decade decline in EU solar deployment surfaces the structural issues everyone knew were coming - grid-connection queues, permitting bottlenecks and market-design gaps - all of which need addressing before Fit-for-55 stays credible. Our energy-transition and market-intelligence teams help developers, IPPs and financiers evaluate European solar-market positioning against those constraints.
