mppalgoritm
MPPT is an electronic system that searches the MPP of a PV panel. It should be
noted from start that MPPT does not use the same principle as mechanical tracking,
where the panel is moved (rotated) in position (azimuth and elevation) so as
maximum sunlight is incident on it. MPPT controllers (trackers) change the output
impedance of the PV panels, thus changing its operating point. However, MPPT can
be used in conjunction with mechanical sun tracking systems to improve power
generation. Typical MPPT controllers make use of a power converter to track MPP of
the PV system.
