Solar energy is one alternative energy that can be used as a source of electrical energy that is converted through solar panel media. The output power in the solar panel varies according to solar irradiation and ambient temperature. To optimize the performance of the Solar Panel, the Maximum Power Point Tracking (MPPT) method is used. Output voltage regulation of the solar panel will be regulated by a parallel buck converter. The algorithm used in this paper is Modified Hill Climbing (MHC) which is used to find the maximum power point quickly and accurately. With the existence of MPPT MHC, the average power is 90.16 W which shows an increase power compared to without MPPT which is equal to 55.78 W.
