This article presents the development of a portable lighting system powered by photovoltaic solar energy to be used by the Chucheros-Buenaventura community. Basic needs of the community and availability of natural energy resources, as well as the use of environment-friendly components, portability and multifunctionality of the lighting system were taken into account in order to evaluate its environmental impact and energy autonomy. The analysis of different materials to be used for the construction of the system's case showed favorable characteristics of the mixture (50/50) of the recycled materials, Polypropylene and High-Density Polyethylene (PPr/HDPEr), compared to others in terms of thermal transference and impact resistance. Furthermore, with the selection of the electronic devices of the lighting system, an energy autonomy of approximately 4 hours was obtained by supplying a current of 500 mA. Finally, the use of available technologies in our context and the use of renewable energies allowed the development of a portable solar light that opens up the possibility of carrying out different basic activities of people and contributes, not only in their improvement of the quality of life in Non-Interconnected Zones (NIZ) homes, but also as an environment-friendly technological alternative for general use lighting.
