Impact of Sahelian Climate Variables on Solar Photovoltaic Output

Energy Science &Engineering, EarlyView.
ABSTRACT Solar photovoltaic (PV) energy is a critical pathway for advancing the energy transition in the Sahel. However, PV module performance in this region is strongly constrained by extreme climatic conditions. This study investigates the effects of (1) wind speed, (2) relative humidity, (3) temperature, (4) dust deposition, and (5) solar irradiance
