Using the parameter values obtained by (8)-(11), (2) will be solved again for Idc for a range of Vdc values within {0,Voc}. This will produce the I-V characteristic at the given temperature and insolation level; the P-V characteristic will be obtained by multiplying Idc and Vdc and the maximum power point will be determined. The DC power thus obtained at the ambient condition will be converted to the AC power using the inverter. Inverter efficiency ηinv, PV module mismatch factor ηmm and dirt factor, ηdirt, [9] will be considered to obtain the converted AC power from DC current and voltage using,
