PVcell mismatch simulation #160

Open beingwei opened 7 months ago

beingwei commented 7 months ago

Can PVmismatch simulate the effect of different cells and voltages on module power output for the same cell power in a 132 cell half-cell module?

mikofski commented 7 months ago

Can you elaborate more on your question?

Can PVmismatch simulate the effect of different cells?

yes every cell can have distinct diode model properties: Isat1, Isat2, Rs, Rsh, band gap, alpha_Isc, etc

voltages on module power output for the same cell power in a 132 cell half-cell module?

I don’t understand the question. Pvmm will solve the electric circuit equations and determine the family of (voltages, current) pairs that satisfy Ohm’s & Kirchhoff’s laws. For a module you can determine the module current and individual cell voltages that add up to the module voltage (this depends on the type of module).
