A training course for photovoltaic trainers was organized at the Thiès training center over 10 consecutive days, bringing together 9 trainers. The training provided an opportunity to build 3 solar systems (1 SHS, 1 stand-alone fridge, 1 solarization system for the training center) from sizing to installation, as well as practical work and role-playing for the trainers (preparation and execution of practical work by the trainers, fault simulation, etc.) with a focus on training andragogy (preparation, trainer's posture, sequencing, etc.).
