Currently, the use of solar panels in Indonesia is still in a stationary position (static) so that the absorption of sunlight is less than optimal due to frequent weather, cloudy weather, and during the afternoon until the afternoon the suns light has turn back/or is not parallel to the solar panels. To obtain optimal electrical energy, the solar panel systems must be equipped with a control-systems and equipped with an RTC (Real Time Clock) sensor module which functions to provide real time data/or components to adjust the direction of the surface of the solar panel so that it always faces the sun at a given angle (tracking based on the movement of the earth) so that the energy from the suns ray can completely fall to the surface of the solar panel. And from the data obtained on December 13, 2021, the output produced by a 10 Wp solar panel tracking system for 9 (nine) hours with a 5 Watt lamp load produces a total power of 3.392 Wh while a non-tracking 10 Wp solar panel produces a total power of 19.658 Wh and the difference between the two 10 Wp solar panels is 15.732 Wh.

Based on the results of the design and testing, it can be concluded that a tracking solar panel has been successfully made and designed with an RTC sensor that rotates approximately 1200 degrees.The solar panels move 90 degrees every hour through the help of a servo motor that can follow the direction of the suns rays following the time cycle.Furthermore, the power generated by the 10 WP tracking solar panel produces a total power of 35.392 Wh, while the non-tracking 10 WP solar panel produces a total power of 19.658 Wh, resulting in a difference of 15,732 Wh.

Further research could investigate the integration of weather forecasting data to proactively adjust the solar panels tracking, anticipating cloudy conditions and optimizing energy capture even before sunlight is obscured. Additionally, exploring the use of more advanced algorithms, such as machine learning, to predict solar movement with greater accuracy and adapt to local environmental factors could significantly enhance tracking efficiency. Finally, a comparative study evaluating the cost-effectiveness and long-term reliability of different actuator technologies – beyond servo motors – for solar tracking systems would be valuable, considering factors like energy consumption, maintenance requirements, and overall system lifespan. These investigations will contribute to the development of more intelligent, efficient, and sustainable solar energy solutions for diverse environments and applications, ultimately promoting wider adoption of renewable energy sources.
