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.

Arrays of solar cells are used to make solar modules that generate a usable amount of direct current (DC) from sunlight. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Adjusting for inflation, it cost $96 per watt for a solar module in the mid-1970s. Process improvements and a very large boost in production have brought that figure down more than 99%, to 30¢ per watt in 2018 and as low as 20¢ per watt in 2020. Solar cell efficiency may be broken down into reflectance efficiency, thermodynamic efficiency, charge carrier separation efficiency and conductive efficiency.
