Solar Lighting for a Festive Atmosphere in Bessens


Located in the southern part of the Tarn et Garonne department (82), the municipality of Bessens demonstrates its commitment to innovation and sustainability with its recent solar lighting project. Driven by its desire for an energy transition, the town hall of Bessens faced a significant challenge: finding a reliable and environmentally friendly autonomous lighting solution. They turned to the Departmental Energy Syndicate of Tarn-et-Garonne (SDE 82) to achieve this. It had to find a suitable lighting solution for this project. Leveraging their experience from previous projects with Sunna Design and their solutions, SDE 82 naturally chose these technologies to tackle this challenge on Chemin de Lalande.

Addressing Urban Challenges with Intelligent Autonomous Solar Lighting


This desire to use solar lighting aligns with an overall approach to energy efficiency in response to current economic and environmental challenges. The primary objective was to find reliable, high-performance lighting that could power decorative lighting without being connected to the electrical grid. Because the electrical grid was unconnected to Chemin de Lalande, much of it lacked public lighting. This absence of traditional lighting had long been a concern for residents, particularly regarding safety and comfort.

The undeniable advantages of the EverGen Range

To meet the specific needs of Bessens, the choice was made to implement Sunna Design’s EverGen solution, a new range of high-power autonomous solar streetlights. Combining cutting-edge technology and durability, this product stands out for its robustness and extended autonomy, providing optimal lighting in all conditions. At the heart of this innovation lies the new generation SunnaCore electronic board, ensuring dynamic energy management that adapts to different lighting profiles and weather conditions, guaranteeing uninterrupted operation.


Beyond the technology itself, the impact of this project on daily life in Bessens has been profound and widely felt. Sunna Design’s Rise-On option has genuinely transformed the atmosphere of the town’s streets. This functionality allows for the connection and efficient powering of decorative lighting using the solar energy produced.

Towards a Sustainable Economy: Cost Reduction and Energy Autonomy


By harnessing solar energy, a renewable and autonomous resource, for its public lighting, Bessens demonstrates its commitment to sustainability and reducing its carbon footprint. Furthermore, the adoption of this independent energy source by the municipality results in a significant reduction in energy expenses. As a result, the high costs typically associated with traditional lighting are avoided, contributing to considerable savings for the municipality.


In addition to providing efficient and reliable lighting for Chemin de Lalande, these autonomous solar streetlights have played a key role in nighttime safety and the well-being of residents. Initially intended for festive periods, the garlands powered by these streetlights have been so well-received that they have become permanent, creating a warm and welcoming atmosphere throughout the year. These points of light now contribute to a festive ambiance, strengthening the sense of community and friendliness in daily life in Bessens.
