Located in the heart of a strategic industrial zone, Avenida Azagador de la Torre was equipped with outdated lighting, including old lanterns, deteriorated wooden poles and an ageing electrical network. To modernize this roadway without heavy construction works or disruption to nearby businesses, the City of Valencia entrusted the project to Grupo ImesAPI, a local specialist in energy efficiency. To meet the performance and sustainability objectives of the project, ImesAPI selected autonomous solar solutions from Sunna Design, installed in partnership with our local partner Grupo S&S.
Avenida Azagador de la Torre, Valencia – SPAIN
UP2 & iSSL Maxi
Before the renovation, the roadway suffered from a lack of uniformity: several areas remained underlit, especially on the right-hand side, while the newer network on the left did not provide consistent visibility. This imbalance affected night-time safety in a zone used daily by employees, heavy vehicles and logistics traffic.
The presence of overhead cables, ageing poles and fragile electrical feeds made renovation through the conventional grid complex and expensive. To avoid trenching, traffic disruption and heavy civil works, the City of Valencia opted for a solution capable of modernizing the avenue without relying on the electrical grid. The autonomous operation of Sunna Design’s solar systems enabled a clean, fast and non-disruptive installation throughout the industrial area.
To modernize the entire roadway, 37 autonomous solar streetlights were installed:
– 32 UP2, with a 2700 K color temperature, mounted on 6 m poles
– 5 iSSL Maxi Road, also set to 2700 K
The spacing, 28 m for UP2 and 24 m for iSSL Maxi Road, ensures continuous lighting uniformity along the entire avenue.
The before/after photos clearly show the impact: the new solar luminaires deliver a more uniform light, better lateral distribution and a warmer atmosphere, enhanced by the 2700 K color temperature chosen to preserve nocturnal biodiversity. The roadway now appears modern, readable and safe for all users.
Thanks to optimized photometry and precise luminaire tilt control, the solar solution delivers far greater uniformity and lighting depth than the former grid-based system. Shadowed areas have disappeared, and night-time visibility has significantly improved.
Solar lighting allows the City of Valencia to avoid:
– connection and grid extension costs,
– trenching and civil engineering works,
– energy expenses,
– heavy maintenance.
The initial investment is generally recovered within a year, thanks to the elimination of operating costs.
Producing 100% solar energy, avoiding invasive works and using a warm 2700 K light significantly reduce the project’s environmental footprint. This renovation is fully aligned with a local strategy of energy sobriety and sustainable urban improvement.
The industrial area now benefits from continuous and reassuring lighting, improving the movement of employees and vehicles. Users can better perceive distances and obstacles, which strengthens the overall safety of the avenue.
Sunna Design’s solar streetlights, equipped with robust NiMH batteries and reliable electronics, offer a long service life with minimal maintenance. The renovation enhances the image of the industrial zone while reducing operating costs for the community.
The solar renovation of Avenida Azagador de la Torre demonstrates the relevance of autonomous lighting solutions to modernize an industrial area quickly and sustainably. Sunna Design has transformed an aging roadway into a high-performance, uniform and fully autonomous lighting axis. Solar technology stands out as a modern and advantageous alternative to the conventional grid, both economically and in terms of performance and durability.

Following the devastating fires of summer 2022 in Gironde, Camping de la Dune, or “Les Flots Bleus,” known from the “Camping” movie series, was forced to rethink its infrastructure completely. Under the leadership of Franck Couderc, the campsite embraced an ecological vision for its revival. Reducing visual pollution and the environmental footprint were vital priorities, […]
As part of its commitment to enhancing its public lighting system, the municipality of Cambes, supported by the Gironde Departmental Syndicate for Energy and Environment (SDEEG), has opted for autonomous street lamps. Sunna Design’s solar solutions were chosen for this project, their extensive range effectively meeting the specific needs of the two involved areas. […]
