This paper presents a computational tool developed in the GUIDE environment of MATLAB, which helps with the analysis and project of GCPVs. The improvements implemented, related to the use of new mathematical models, aim results closer to reality, making the forecasting more accurate. Special attention is given to the operational characteristics of GCPVs, mainly those related to the inverter’s limitation by power and temperature. At last, the validation of the results is presented, in terms of energy, by comparing the data generated by the program and measured data from operating systems.
