Abstract Use of renewable energies in remote places with no access to main electrical infrastructure becomes fundamental to guarantee equity as well as affordable and clean energy, impacting the United Nations Sustainable Development Goals (UN SDGs). There is also fundamental correct and effective capacitation to operators, to avoid expected-lifetime reductions due to malfunctioning or maloperation. In this paper, the case of Isla Múcura is studied: Photovoltaic (PV) system and storage diagnosis, recovery and community capacitation activities were performed in a fishing and tourism-based community with no knowledge about electrical infrastructure. It was detected that correct capacitation and reliable information devices are fundamental to improve maintenance, operation, and management of the overall generation system
