Simulink Model of PV System

The photovoltaic array is nothing but modules connected in series and parallel. The PV array for the SRFCs consists of several modules, which in turn consist of solar cells. The solar cells used in designing the present PV array are crystalline Si solar cells. The appropriate cell details are given in the Table 12.2. 

during the day, the solar irradiation from the sun is not at a constant wattage of 1000 W/m. It varies from a minimum to a maximum. The solar irradiation or the flux for any given day is like a positive sine curve. For the Simulink model, the flux is the input and the output is the power produced by an array. Just changing the number of cells or modules that are connected in series or parallel can alter this power. 

The PV module consists of Np parallel branches, each of Nsm solar cells in series. (From Hansen, A. D. et al.. Models for stand-alone PV system. Riso National Laboratory, Report Rlso-R-1219(EN)/SEC-R-12, Roskilde, Denmark, 2000.)
