Overall dimension
Maximum Power Point Tracking
Upper curve:
Output current () of a solar panel as function of output voltage (M).
■ The maximum power point (MPP) is the point
Pmax along the curve where the product | X V reaches its peak .
Lower curve:
■ Output power P= Ix V as function of output voltage.
When using a PWM (not MPPT) controller the output voltage of the solar panel will be nearly equal to the voltage of the battery, and will belower than Vmp.
