Figure 7. Supply and load connections

An electric “solar array simulator” (SAS, SAS-FL05/01 from CBL Electronics) has been used

to simulate polycrystalline PV modules with 2, 3 and 4 PV cells in series and with different

sizes to supply currents from 100 mA up to 900 mA (by 100 mA steps).

Figure 8 to Figure 13

show the I-V and P-V curves generated by the SAS, obtained using a PV module analyzer

ISM490 from ISOTECH (only 100 mA and 900 mA cases are reported).
