With the values of the parameters obtained by (4)-(6), I-V characteristic represented by (2) is solved for Idc for a range of Vdc values, {0,Voc,STC}. The maximum calculated power, according to the model, is obtained by determining the maximum value from (Vdc x Idc). Iterations will be continued until the absolute difference between this calculated maximum power and manufacturer provided maximum power becomes less than a tolerance value in the order of 1×10-4.
