Improved Synthesis of Global Irradiance with One-Minute Resolution for PV System Simulations

Table 3

Root mean square errors (RMSE) of the frequency distributions of irradiance gradients of modelled data versus measurement in W/m². The new model is able to produce significantly smaller values of RMSE than the models of Aguiar and Skartveit for both locations, Lindenberg, 2005, and Carpentras, 2001.
