In this study, solar television power supply with microcontroller was designed and implemented. An investigation has been made for the maximum power point tracking (MPPT) methods in order to get energy most efficiently from solar panel output. A hybrid method combination of read from table method and perturb observe method was chosen. Based on meteorological database, the table which contains data of radiation and temperature at different levels was formed. The data in the table has been used by hybrid system.It was planned to supply 21,6 inch size LED television by photovoltaic energy in this study. The designed power supply consists of control unit capable of maximum power point tracking and power unit. Buck type converter was used in the designed control unit capable of maximum power point tracking. In order to avoid damage of the system, protection features were added to hardware and software of control unit.
