摘要：

This paper presents a comparison of the energy production in grid-connected photovoltaic systems (GCPPS) from measured and calculated radiation data. The Linke turbidity (TL) factor for the region of Porto Alegre, Brazil, was extracted considering the data of direct solar radiation from the typical meteorological year (TMY). The average annual turbidity value obtained of 4.03 agrees with the wet climate of the region which presents only 17.26% of clear-sky days. There was a difference of 27.5% in the results of the produced energy, which drops to 6.5% when compared with only sunny days in the region, suggesting that the model in the current configuration for this type of estimate is barely adequate.
