Very good model.
If someone doesn't has SimElectronics all components but the "PV Panel" Submodel can be deleted as the "PV Panel" can run without SimElectronics.
In my opinion there is a small error
that has to be fixed in the submodel.
The "Reversed Saturation Current at Top Eqn" must use Tref instead of Top.
Because the Equation is Irs = Isc/(exp(q*Voc/(K*N*T_ref))-1);
At least this is written in "Insolation-oriented model of photovoltaic module using Matlab/Simulink" from Huan-Liang Tsai.
I fixed this in my model an the simulation result compared to the datasheet (of a Shell S36 solar cell) improved a lot.
Ki: Temperature coefficient of short-circuit current [A/°K];
KV: Temperature coefficient of open-circuit voltage [V/°K]
But KV is not used in the model (As far as I have seen it), even though it is defined in the submodel, so you can ignore it.
