Articolul prezinta modelarea panourilor solare cu ajutorul parametrilor tehnici din catalog si a unui model matematic care are la baza circuitul echivalent al panoului cu o singura dioda. Modelul matematic a fost implementat initial in MATLAB/Simulink iar rezultatele simularilor au fost comparate cu valorile si caracteristicile tehnice din catalog. De asemenea, pentru a studia diferite fenomene si caracteristici ale invertoarelor fotovoltaice, atat in regim stationar dar si tranzitoriu, cat si impactul conectarii la o micro-retea de distributie alaturi de alte surse regenerabile si sisteme de stocare a
energiei, a fost dezvoltat si implementat intr-un pachet de programe dedicat PowerFactory un model similar care are labaza acelasi model matematic implementat initial in MATLAB/Simulink si aceeasi parametri tehnici din catalog.

Abstract
This paper presents a PV panel simulation model using the single-diode four-parameter model. The model was
implemented in MATLAB/Simulink, and the results have been compared with the data sheet values and characteristics of
the PV panels in standard test conditions. A PV system model, using the same equations and parameters as in
MATLAB/Simulink to define the PV module and characteristics, has also been developed and implemented in
PowerFactory to study load flow, steady-state voltage stability and dynamic behavior of a distributed power system.
