The output current from each solar module was measured from zero
(open circuit) to the maximum current (low load resistance) at which at the output power density of solar cell is less than 10% of that at the MPP. Table 2 shows the range of output currents at which the solar cells
can generate at least 90% of the power density at the MPP for the illumination source being tested at an illumination level of 500 lx.
