Before looking into consequences of the third solve, I would first look at the second solve. Conopt fails because the Jacobian values are too big. Knitro can't make the model feasible. You did not share the log/lst of your run. Did you succeed solving the second ("Thermal") model? Only if...

When I run the model the listing file points me to the problematic equation "**** Exec Error at line 449: overflow in * operation (mulop)". Line 449 reads "E90..I_pv =e= IL1L - (Io1L * ((exp((Vb + (I_pv * Rs1L))/(a1L + 0.01))) - 1)) - ((Vb + (I_pv * Rs1L))/(Rsh1L + 0.01));". So ...
