Home Solar lighting blog Case studies Valencia’s winning investment in solar streetlights
In the city of Valencia, Spain, the observation is clear: many residential streets are equipped with obsolete public street lamps. Having already called on Sunna Design for the successful installation of solar street lamps in one of its parks, it was only natural that the municipality, along with the ETRA company in charge of street lighting maintenance, turned to this same solar technology.

Several small residential streets of Valencia are equipped with aging urban streetlights, unadapted to current energy and ecological challenges. The sodium lamps of these streetlights are very energy-consuming. The electrical network itself is obsolete, and would require a complete overhaul to bring the installation into compliance.
Replacing an existing street lighting system with conventional lighting involves heavy works: trenches, cabling, electrical panel, etc. Here, the entire electrical system must be renovated to comply with standards. Sodium lamps must be replaced by more recent and energy-efficient LED lamps. These interventions are both long and costly, just as unsatisfactory for the municipality as for its residents.
In 2021, the technical managers of the City of Valencia and the installer ETRA informed Sunna Design of their street lighting renovation project. A financial analysis of the situation made it possible to highlight the relevance of a solar street lighting solution for the residential areas concerned.
Sunna Design’s solar solutions allow for a fast renovation of the lighting system and present an overall investment cost equivalent to that of a conventional lighting system, the additional cost of the solar street lamp being offset by the savings made in terms of renovation of the power supply network. The operational cost is also very low thanks to the absence of an energy bill.
The City of Valencia also wanted to reduce the energy impact of its public lighting by turning to lighting solutions powered by renewable energy, for a renovation in line with the sustainable development. A total of 98 iSSL+ streetlights have been deployed, with a color temperature of 2700K to reduce the impact of street lighting on biodiversity, the Valencia region being quite tree-filled and with significant local fauna and flora.
Solar street lighting of Valencia will have cost the city less than renovating its conventional lighting system. Robust and reliable, guaranteed for 6 years and with a sober and elegant design, Sunna Design’s solar street lamps allow cities to provide efficient lighting with excellent uniformity in record time, for streets lit in a way that is just as beneficial for the inhabitants as for nature.
