Development of a clear-sky model to determine circumsolar irradiance using widely available solar radiation data

Edgar F. M. Abreu, Paulo Canhoto, Maria João Costa Accurate assessment of the solar irradiance reaching the absorber of concentrating solar power (CSP) systems is crucial for accurate energy generation estimates as well as for power plants design and operation. Due to a larger aperture angle, direct normal irradiance (DNI) measurements taken by pyrheliometers include […]
