Public Fotovoltaic Lighthing : Technical and Socio Economicy Assesment

Abstract

This research analyses, based on different criteria, the viability of projects consisting of public street lighting installations powered by photovoltaic solar energy. First, an analysis of the existing technological capacity in this market for photovoltaics (PV) street lighting is generated. Later, the requirements, work, problems and costs identified are studied for two possible options to renew an aerial grid public lighting installation: channelling the electrical wiring or installing new autonomous LED PV luminaires to cover the regulatory requirements. This comparison is contextualized in the context of a study case located in a municipality with a population of approximately 5,000 habitants in the Island of Lanzarote (Las Palmas, Spain)

The paper is completed presenting a statistical study that assesses the social acceptance of Spanish citizens of this type of technology in urban environments, from the aspects of improving urban sustainability, operational safety, visual impact and perception of risk of vandalism.
