Projected beam irradiation at low latitudes using Meteonorm database

Hatwaambo, Sylvester; Jain, Prem C.; Perers, Bengt; … - In: Renewable Energy 34 (2009) 5, pp. 1394-1398

The quantitative analysis of beam radiation received on a solar concentrator may be understood by evaluating the projected solar height angle or profile angle along the north–south vertical plane. This means that all the sunrays projected along the north–south vertical plane will be...
