Abstract
As the electric power supplied by solar arrays is dependent upon the insolation, temperature and array voltage, it is necessary to implement Maximum Power Point Tracking (MPPT) in order to move the solar array operating voltage close to the peak power point, therefore drawing the maximum power from the solar array. The solar panel shall be integrated with a dc-dc converter and a control algorithm, performed by the microcontroller, to perform a search to track the maximum power continuously. The method described shall be applied to a solar generator; an array of photovoltaic cells, in order to charge a storage battery. The dc-dc converter is responsible for the regulation of the output voltage at the peak power point while also providing a constant voltage to the charging battery. Impedance matching is also carried out by the dc-dc converter to ensure maximum power transfer. This paper describes some existing maximum power point tracking algorithms and introduces two new proposed methods.
