Creation of a knowledge management model based on CBR: Application to the maintenance of autonomous solar photovoltaic installations

This paper proposes a solution to facilitate the maintenance activities of autonomous solar photovoltaic (PV) installations. With the growth of autonomous PV installations, in developing countries, it is now essential to focus on the maintenance activity. The autonomous PV installation meets the electricity needs, on the one hand, in remote areas. On the other hand, it allows to avoid the constraints of connection to the electrical grid. However, to have an efficient and reliable PV system, a safe and proper maintenance is essential. This work focuses on the capitalization of knowledge in maintenance activity. The objective is to propose a model able to help the maintenance technicians during their interventions by providing them with knowledge elements which will be drawn from a knowledge base. This knowledge base is built from the knowledge collected during the previous maintenance activities of a given PV installation.
