Figure 1-2 shows the MPPT curve; the shaded area is the charging range of a
traditional solar charge controller (PWM Charging Mode), which illustrates how
the MPPT mode can improve the usage of the solar energy available. According
to our tests, the MPPT controller can improve efficiency by about 20%-30%
compared to the PWM controller. (Actual result may vary due to the influence of
cloud, temperature and other ambient circumstances.)
Figure 1-2 Maximum Power Point Curve
In real-world applications, such as shading from clouds, trees or snow, the panel
may appear Multi-MPP, but in actually there is only one real Maximum Power
Point. As the below Figure 1-3 shows:
