Maximum Power Point Tracker Based on Perturb and Observe Algorithm in the Dual Axis Solar Panel Tracking

Digitalization era is now growing very rapidly encouraging individuals from each human being to try hard to find a variety of equipment that can support human life so that almost some of the available equipment requires an electrical energy supply. The power sources utilized by existing power plants in Indonesia mostly come from fossils that are already threatened with availability and cause greenhouse effects. Such utilization can threaten the sustainability of human life and the environment. Then renewable energy is needed that is able to replace fossil energy. Renewable energy that can be used as a power plant include solar, wind, water and so on. Solar energy is the right form of energy source to be developed, because it is a high capacity energy source, continuous, not pollute and can be utilized for free. But solar panels can only convert energy from sun into electrical energy about 14% of the total energy obtained from the sun. Therefore, it is necessary for MPPTs to maximize the output power of the solar panels. Testing using MPPT generates a power of 13.48 W, while when without using MPPT only 8.44 W.
