The winning bet of solar road lighting


After the completion of several projects that have met all the expectations of both residents and operations managers, the municipality of Valencia, Spain and Sunna Design continue their successful collaboration on the solar street lighting of the city. The ministry of territorial policy, public works and mobility did not hesitate to contact Sunna Design’s teams to study the viability of a solar road lighting project.

One road lighting for three objectives: safety, energy management and ecology


In Valencia, the CV-35/Godella traffic circle section of the road CV-31 does not have public lighting. In order to improve the safety of this road, the ministry of territorial policy of Valencia asked Sunna Design and the ETRA group to develop a lighting system.


The overall objective being to take a new step in the energy efficiency project initiated in October 2015, it was essential that the selected public lighting solution met three key criteria: the levels and quality of road lighting prescribed by the regulation on the energy efficiency of outdoor lighting (royal decree 1890/2008 of November 14), the reduction of electricity consumption thanks to the new led lighting technologies, and finally the reduction of CO2 emissions and light pollution through the use of cleaner and more sustainable energy.

A solution to all the problems of road lighting: the solar streetlight


The solar street lamp quickly emerged as the answer to all the criteria established by the ministry in charge of the maintenance of public lighting on the roads of Valencia. From a technical point of view, the autonomous streetlight allows lighting the CV-31 road without waiting and with a minimum impact on traffic, requiring no civil engineering works but simple foundation works. This system also allows considering a future widening of the road in the context of which the solar streetlights will only have to be moved, the whole lighting system being reusable (no pipes, wiring, control panels, etc.). From an energy point of view, the photovoltaic street lamp reduces the electricity bill to zero, while providing lighting powered by a clean energy in line with the sustainable development objectives of the city of Valencia.


After studying the needs of road CV-31 in terms of street lighting, Sunna Design’s teams developed a customized solar lighting project adapted to road lighting standards. 38 intelligent street lamps from the EverGen range were deployed along the section of road concerned, on 7-meter high masts with a 28-meter spacing, to guarantee a constant illumination of 15 lux and a lighting uniformity greater than 0,40.

Sunna Design’s solar solutions have once again convinced the municipality of Valencia for their unequaled reliability, their 6-year warranty on the entire product, not to mention their sober and elegant design. The EverGen range, equipped with the new generation of the SunnaCORE technology, offers high power lighting suitable for road safety. All Sunna Design streetlights are equipped with a patented electronic card called SunnaCORE, whose algorithms allow ensuring lighting continuity thanks to their anti-blackout function, particularly valuable in winter when solar irradiation is less important.


By choosing Sunna Design’s solar technology once again, Valencia was able to equip its road with a reliable and sustainable street lighting system in record time, for the safety and comfort of users of its roads.
