EU Rooftop Solar Mandates Set to Drive the European Rooftop Solar Panel Market from $11.2 Billion in 2025 Through 2035 at a 5.7% Growth Rate

European rooftop solar panel market stood at $11.2 billion in 2025 and is expected to expand to $19.5 billion by 2035, registering a CAGR of 5.7% over the 2026–2035 forecast period. The introduction of the EU Rooftop Solar Standard under the revised Energy Performance of Buildings Directive (EPBD) is positioning rooftop photovoltaic systems as a central driver of distributed solar expansion across the European Union. By requiring buildings to be more solar-ready and unlocking large rooftop surfaces on offices, commercial buildings, and car parks, the policy strengthens incentives for solar installations. This regulatory shift is expected to support broader renewable energy goals, reduce energy costs for public institutions, and accelerate clean power deployment from rooftops in cities and communities throughout the EU.

According to SolarPower Europe’s preliminary analysis, the successful implementation of the Rooftop Solar Standard could generate enough electricity to power the equivalent of 56 million European homes and drive the installation of 150 to 200 GW of additional rooftop solar capacity between 2026 and 2030. The analysis builds on estimates from the EU Joint Research Centre that the EU has rooftop solar potential of about 580 GW capable of generating 680 TWh a year, which could cover around one?quarter of the EU’s annual electricity demand if fully deployed.

Advancements and Investments Accelerate European Rooftop Solar Adoption

• In May 2025, LONGi Solar’s Hi-MO X10 back contact module received the Smarter E AWARD 2025 in Photovoltaics for its advanced technology.

• In May 2025, GreenYellow secured €49 million to develop a 116?MW rooftop photovoltaic portfolio across 2,318 Biedronka stores in Poland.
