A New Approach in Controlling A Single Axis Solar Tracker Based on Photovoltaic Output

Harvesting energy from the sun is a trend in this era. One of the strategies in collecting this solar energy is using a solar panel with a solar tracker to find an optimum value of this power. There are many strategies to track sunlight movement both on the single-axis or double axis. In this paper, a new method in finding an optimum energy collection is proposed. This new approach applies a mini solar tracker driven by a micro servo motor as a sunlight sensor. This method's strategy is to multiply the output voltage and current from the mini solar panel to get a maximum power value at a specific degree for driving the larger servo motor at larger PV. As a result, energy supply to the larger motor is reduced. The results show that this strategy can find optimum power from the sun's energy.
