An independent photovoltaic power generation system comprises a solar cell component, a DC converter and a storage battery. A working method for the tracking maximum power of the independent photovoltaic power generation system is characterized in that the method comprises the following steps: establishing the independent photovoltaic power generation system and determining the composition of the system; determining the input signal and the output signal of the DC converter; determining the relationship between the action for tracking the maximum power of the solar cell component and the action of the DC converter; and determining the work plan for tracking the maximum power of the system. The invention has the following advantages: (1) the structure is structure and has various loads; (2) the adoption of tracking method of maximum power can improve the working efficiency of the solar cell to ensure that the maximum electric energy can be supplied to the load; (3) simultaneously, a DC booster transformer is installed between the solar cell and the load to improve the output voltage of the photovoltaic cell so as to meet the requirements for voltage of the load.
