A photovoltaic array (PVA) simulation model to be

used in Matlab-Simulink GUI environment is developed and

presented in this paper. The model is developed using basic

circuit equations of the photovoltaic (PV) solar cells including the

effects of solar irradiation and temperature changes. The new

model was tested using a directly coupled dc load as well as ac

load via an inverter. Test and validation studies with proper load

matching circuits are simulated and results are presented here.
