France Solar Installations Capacity Growth
France added 7.6 GW of solar capacity in 2025, bringing its total installed photovoltaic capacity to 38.3 GW by year-end, according to industry reports. This increase represents a significant rise from approximately 16 GW in 2022, as nearly 5.9 GW were added within the same year.
Record Solar Generation from France Solar Installations
In 2025, solar generation reached a record 44.3 TWh, indicating an escalating reliance on solar power in the nation. The rise in capacity and generation underlines the growing requirement for energy storage solutions and system flexibility.
Factors Driving France Solar Installations Expansion
The rapid expansion of installed capacity has been supported by diverse project types, including ground-mounted solar installations, commercial rooftops, and building-integrated photovoltaics (BIPV). Future forecasts forecast a compound annual growth rate (CAGR) of 9.5% in the French solar market from 2026 to 2036, fueled by continued support for utility solar and BIPV initiatives.

Challenges Facing France Solar Installations Sector
Despite notable growth, the market faces several challenges, particularly regarding grid constraints. According to the Réseau de Transport d’Électricité’s (RTE) network strategy, while 10 to 20 GW of additional grid capacity has been preserved, investment savings of EUR 1.5 billion were documented between 2019 and 2025. Additionally, issues such as delayed approvals for building-integrated solar solutions contribute to prolonged project timelines.
In 2025, nearly 3 TWh of solar and wind generation were curtailed due to grid limitations, reflecting the pressing need for enhanced energy storage capabilities to manage growing production levels effectively. Furthermore, supply bottlenecks and volatile equipment costs have intensified market challenges, complicating installation efforts.
France’s unique regulatory environment combines a focus on BIPV with a building culture that rewards the usage of validated solar materials, positioning it for continued growth despite encountering several operational hurdles.
