This has been done in this thesis by proposing and implementing the both systems one of these system is to use a maximum power point (MPP) tracker and the other is to use a sun tracker. Both systems are mathematically modeled and simulated by using MATLAB - Simulink and M - file. Moreover, the two systems are implemented experimentally by using AVR ATMEGA microcontroller ER -
