Evaluating tilted plane models for solar radiation using comprehensive testing procedures, at a southern hemisphere location

This work aims at assessing the performances of four models for their relative merits in estimating diffuse solar radiation on tilted planes for a southern location (Reunion Island). This comparative study benefits from a sound and consistent experimental set-up and is more detailed than the previous research works as 14 inclined planes are available for testing.

► Assessment of 4 tilted plane models for evaluating the incident solar irradiance in a southern location. ► Experimental data from 14 different inclined planes. ► Comprehensive testing procedure.
