1.4 Results and Discussion
ОглавлениеThis section presents the simulation and experimental results of estimated parameters of SPV panel. The effectiveness of numerical methods is tested on various panels like KD245GX, U5-80 and Shell SP70 under STC and varying environmental conditions. The manufacturer’s data of short circuit current (Isc), open circuit voltage (Voc), number of series cell (Ns), maximum output current (Impp) and output voltage (Vmpp) at STCs are given in Table 1.1. The numerical solution obtained for the aforementioned PV panels using GS and NR techniques in MATLAB. The comparative analysis of results found exhibit that the performance of NR technique was superior to the GS method under dynamic environmental conditions. Hence, the effectiveness of NR technique was compared with the experimental data recorded for HST60FXXXP PV panel through its P-V and I-V characteristics analysis.
