“…Such performance could be obtained from the manufacturer supplied datasheet of the module (Farivar and Asaei, 2011;Chatterjee et al, 2011;Lo Brano et al, 2010;Ahmad et al, 2012;Cubas et al, 2013;Siddique et al, 2013;Sera et al, 2007;Chenni et al, 2007) or from experimental measurements (Chenni et al, 2007;Chan and Phang, 1987;Maoucha et al, 2012;Phang et al, 1984;Jia et al, 1995;Ortiz-Conde et al, 2006;de Blas et al, 2002;Bouzidi et al, 2007;Chan et al, 1986). The mathematical expressions of module parameters are usually nonlinear and require iterative numerical solutions (Chatterjee et al, 2011;Lo Brano et al, 2010;Siddique et al, 2013;Sera et al, 2007;Chenni et al, 2007;Chan and Phang, 1987;Maoucha et al, 2012;Ortiz-Conde et al, 2006;Bouzidi et al, 2007); however, certain assumptions can enable the separation of variables and allow direct solution to identify the parameters (Farivar and Asaei, 2011;Ahmad et al, 2012;Cubas et al, 2013;Phang et al, 1984;Jia et al, 1995;de Blas et al, 2002;Chan et al, 1986). Although most of the work reported in literature considers the single-diode model of PV cells, a few publications are concerned with parameter estimation of the double-diode equivalent circuit Chan and Phang, 1987;Maoucha et al, 2012).…”
