The SPS PV array model implements a PV array built of series- and parallel-connected PV modules. It allows modeling a variety of preset PV modules available from NREL System Advisor Model (Jan. 2014) as well as a user-defined PV module. The PV array block has two inputs that allow you to supply varying sun irradiance (input Ir in W/m^2) and temperature (input T in deg. C) data.

In our example, the PV array consists of one string of 14 Trina Solar TSM-250 modules connected in series. At 25 deg. C and with a solar irradiance of 1000 W/m2, the string can produce 3500 W.

Two small capacitors, connected on the + and - terminals of the PV array, are used to model the parasitic capacitance between the PV modules and the ground.
