maximum power point tracking (MPPT)

Maximum Power PointTracking (MPPT) is an optimization method used in photovoltaic systems and solar modules that ensures that the operating point of

the solar modules is shifted so that they always achieve the highest feed-in power. In photovoltaics, the energy generated depends on the solar radiation. The operating point at which the solar cell generates the most energy changes with the solar irradiation. The Maximum Power Point (MPP), which is the optimal operating point, shifts, which has a direct impact on the efficiency of the feed-in. With maximum power point tracking, the MPP point is constantly tracked by the inverter or grid-feeding device

, which leads to an improvement in feed-in efficiency. The better the MPPT algorithm, the higher the feed-in efficiency.
