About solar lighting 13 November 2025
In 2025, France’s Energy Savings Certificates (CEE) program will evolve, introducing stricter requirements to encourage more efficient and sustainable lighting projects. Autonomous solar lighting remains fully eligible under this new framework, provided it meets the updated standards. Sunna Design solutions already comply with these criteria, offering a reliable and future-proof answer to modernize public lighting while taking advantage of available incentives.
France’s Energy Savings Certificates (CEE) are a key national mechanism supporting the country’s energy transition.
They require energy suppliers and distributors (“obligated parties”) to finance or implement actions that reduce overall energy consumption. These actions generate tradable certificates based on verified energy savings.
In 2025, the technical specification RES-EC-104, which governs outdoor lighting, has been revised to raise the bar for energy efficiency and environmental responsibility.
The objectives are clear:
This updated framework aims to make every public lighting renovation more efficient, responsible, and environmentally conscious.
To qualify for CEE financial incentives, each lighting installation must now comply with a series of enhanced technical standards designed to improve energy efficiency, extend product lifespan, and protect biodiversity.
All new installations must include dimmable luminaires, allowing light intensity to adapt to real-time needs. Light sources must be replaceable, extending the lifetime of equipment and facilitating maintenance.
Each product must also include a performance declaration within the European EPREL database, ensuring full transparency on technical and energy characteristics.
The new rules introduce strict limits on color temperature to protect nocturnal wildlife:
These measures help reduce light pollution and preserve local ecosystems, in line with the “dark sky” initiatives now implemented by many municipalities.
Luminaires must now guarantee a minimum lifetime of 75,000 hours at 25°C ambient temperature. This requirement ensures long-term reliability, minimizes environmental impact from equipment renewal, and reduces maintenance operations.
Each project must demonstrate optimized lighting design:
These lower illumination levels support energy sobriety while maintaining user safety and visual comfort.
All replaced materials must now be collected and recycled. This requirement applies to every component and ensures responsible end-of-life management. Sunna Design partners with recognized organizations : Soren, Ecosystem, and Corepile, to guarantee full traceability and proper recycling of its products. More informations : here.
Lighting systems equipped with presence sensors benefit from additional bonuses. These technologies automatically adjust light levels based on detected activity, further reducing energy consumption and enhancing operational efficiency.
Under this new regulatory framework, autonomous solar lighting meets and often exceeds all updated requirements:
By choosing Sunna Design, you ensure full compliance with the RES-EC-104 specification while enjoying a clean, reliable, and easy-to-install solar lighting solution that unlocks the benefits of France’s CEE program.
The 2025 reform of France’s Energy Savings Certificates (CEE) reinforces eligibility criteria but also opens up new funding opportunities to accelerate the modernization of public lighting. With Sunna Design, you benefit from a turnkey solution, reliable, compliant, and high-performance equipment designed to drive tangible energy transition outcomes.
Sunna Design supports you in analyzing your project, preparing your application, and optimizing your energy performance, ensuring full access to available financial incentives. Take action now and transform your lighting projects into concrete levers for sustainability and efficiency.
While the Energy Savings Certificates (CEE) scheme is specific to France, it reflects a broader global shift toward smarter, cleaner, and more sustainable public lighting, a vision that drives Sunna Design’s innovation worldwide.
Sunna Design supports cities and developers in deploying autonomous solar solutions tailored to all urban or rural environments.
