A study performed by the European Commission has shown that between 30% and 50% of electricity used for lighting could be saved by investing in energy-efficient lighting systems . In Spain, in some municipalities, the consumption of energy in public lighting reaches up to 80% of the total electricity consumption.
The project is different from conventional street lighting systems not only in the sense that it uses solar energy, but more importantly, it is also a stand alone device that provides for an efficient energy management program that ensures effective maintenance and reduced energy wastage due to malfunctioning lighting controls.
A total 88% of the subjects consider a sustainable and adequate solution to renew the installation of urban lighting, and that the new installation is powered exclusively by PV energy. At first glance, there are no relevant differences considering different segments of ages.
In general, most subjects of all age segments are aware of the problem that means having aerial wiring running at facades (95%) and considers the use of PV in urban lighting sustainable (88%). However, 47% of those surveyed consider that shutdowns due to lack of energy harvesting is problematic and 17% consider this very problematic.
