VPANEL (V) 12 14 16 0 Figure 1. A solar cell produces current in proportion to the amount of sunlight falling on it, while
the cellвЂ™s open-circuit voltage remains relatively constant. Maximum power output occurs at
the knee of each curve, where the cell transitions from a constant voltage device to a constant
current device, as shown by the power curves. below a certain set point, the charge
current is reduced. The charging current is adjusted via a control voltage
across a current sensing resistor in
series with the inductor of the buck
regulator charging circuit. Decreased
illumination (and/or increased charge
current demands) can both cause the
input voltage (panel voltage) to fall,
pushing the panel away from its point
of maximum power output. With the …
