The maximum power point (MPP) is the point on the current-voltage (I-V) curve of a solar module under illumination, where the product of current and voltage is maximum (Pmax, measured in watts). The points on the I and V scales which describe this curve point are named Imp (current at maximum power) and Vmp (voltage at maximum power.)power) and Vmp (voltage at maximum power.)
, 2. In photovoltaic systems, the point at which the most possible current is drawn from a cell, and the voltage subsequently drops off. The MPP changes slightly with temperature and intensity of sunlight.
