Test the main circuit DC voltage and output current, calculate the output power of the solar array, and achieve the maximum power point tracking. Disturbance resistance R and MOSFET series together, under the conditions of the output voltage is basically stable, by changing the duty cycle of MOSFET, to change the average current through the resistance, and the current disturbance is generated. At the same time, the output current and voltage of the photovoltaic cell will be changed. By measuring the change of the output power and voltage of the photovoltaic cell before and
after the disturbance, the disturbance direction of the next cycle will be determined. When the disturbance direction is correct, the output power of the solar energy board is increased, and the next cycle continues to move in the same direction. In this case, the disturbance and observation of the solar photovoltaic panels output up to the maximum power point.
