In order to obtain the maximum output power under different weather conditions, the maximum power point tracking (MPPT) algorithm is adopted in a solar power system. This paper develops a new circuit design to enhance the transformation efficiency. An MPPT algorithm denoted Perturbation and Observation (P&O) method is applied for tracking maximum power points of Photovoltaic (PV) system. In this paper, a dynamic load variation circuit design of Perturbation and Observation method for a solar power generation system. The advantage of this approach is that it is a simple algorithm conducting on a microprocessor without redundant circuit components and thus the maximum power point of the solar energy will be obtained quickly and stably. The efficiency of the solar generation system will be enhanced too.
