Maximum Power Point
8.6.3 Maximum Power-Point Tracking The maximum power point (MPP) represents the bias potential at which the solar cell outputs the maximum net power. The MPP voltage can drift depending on wide

The central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on the amount of available sunlight, shading, solar panel temperature and the load 's electrical characteristics. Maximum power point tracking (MPPT), or sometimes just power point tracking (PPT), is a technique used with variable power sources to maximize energy extraction as conditions vary. The technique is most commonly used with When directly connecting a load to cell, the operating point of the panel is rarely at peak power. In such systems the same current, dictated by the inverter, flows through all modules in the string. "Renewable Energy Systems With Photovoltaic Power Generators: Operation and Modeling". Perturb and observeIn this method the controller adjusts the voltage from the array. Although the fully charged battery pack voltage may be close to the PV panel's MPP voltage, this is unlikely to be true at sunrise when the battery is partially discharged.
