I am trying to construct a PV array in simulink. My motto is to observe characteristic for partial shading PV array with different irradiation's for each module.I have modeled individual PV modules as current sources with series and parallel combination of solar cells. According to equations a voltage feedback is required for this. To get this voltage feedback, I have connected a capacitor across current source. For an individual PV module its working fine as desired. Now when I am trying to connect two PV modules of 250W each in series and trying to observe characteristics across two modules by placing another capacitor in total. Instead of expected peak of 500W it is showing 330W.
How to connect two PV modules modeled as current source in series????
Please see the attached simulink file

In MATLAB R2015a SimPowerSystems there is a PVArray block which you can model partial shading. PV module itself is a current source, you just need to configure it to a single module by setting parallel and series string to 1 and select any 250W module from the Module list. To model partial shading you need to connect two PVArray block in series with a bypass diode for each module. Input one PVArray block with 1000 W/m^2 and the other one with 300 W/m^2 for shading effect. Use a ramp block to drive the voltage source as voltage drop load and measure its current, voltage and power using XY Scope to visualized I-V and P-V partial shading curve. I also attached the screen capture and Simulink file for your reference.
For other methods of modeling PV Module you can refer to my file exchange link below

Is .m file available for this instead of slx?

It's in the Simscape/Electrical/Specialized Power Systems/Renewables/Solar
