Abstract

This study evaluates the insolation calculations and their analysis soon after plotting their respective local historical average graph from 1962 to 2019 for some municipalities in Pernambucana. Monthly and annual insolation data for the study period was obtained from the National Institute of Meteorology.After homogenization, data consistency and failure filling of each series, the spatial and temporal insolation densities were performed for municipalities like Arcoverde, Cabrobó, Garanhuns, Ouricuri, Petrolina, Recife, Surubim and Triunfo. The average and its historical average were calculated and appropriate analysis was performed. The spatial distribution of the monthly insolation data showed great variability for the months studied, ranging from approximately 3 to 4 hours. The median values ​​ most likely occured during the months for the eight municipalities under study. The municipality of Garanhuns presented higher insolation values ​​than Petrolina. Comparing the values ​​obtained in this study with the values ​​of the Solarimetric Atlas of Brazil, indicated a good similarity of the recorded data.
