Analysis and experimental verification of the sensitivity of PV cell model parameters

The model parameters of photovoltaic (PV) cell depend on the environmental conditions, especially are function of the temperature and the irradiance values of the site where the panel is placed. In this paper the performances of PV cells/panels are analysed related to the different temperature and irradiance levels by using the circuit sensitivity. Therefore the model parameters of the equivalent circuits for PV cells and their typical connections are modelled by first order sensitivity relations. LabViEW and MatLab software procedures are implemented in order to prove the theoretical models, and to provide numerical examples taken from real case on PV cells.
