This paper describes an automatic sun tracking system, based on two stepper motors, and moving solar panel. To gain more energy from the sun, the active surface of the solar cells should be perpendicular to solar radiation, which means that the panel must follow the path of the sun all the time.
But the continuous change in the relative angle of the sun with reference to the earth reduces the watts delivered by solar panel. In this context solar tracking system is the best alternative to increase the efficiency of the photovoltaic panel. Solar trackers move the payload towards the sun throughout the day.
An automatic solar tracker was designed using a microcontroller, integrating a hybrid algorithm that combines sensors and mathematical models to enhance solar energy utilization under various weather conditions (Tharamuttam and Andrew, 2017).
In this context solar tracking system is the best alternative to increase the efficiency of the photovoltaic panel. Solar trackers move the payload towards the sun throughout the day. In this paper different types of tracking systems are reviewed and their pros and cons are discussed in detail.
Solar tracking systems are commonly used in large-scale solar power installations, such as solar farms or commercial solar projects, where maximizing energy production is crucial. By utilizing solar trackers, these systems can increase their energy output by up to 30% compared to fixed-tilt solar installations.
Developed and analysed the performance of a solar tracker system, comparing it with a fixed PV system (Sidek., 2014). Results indicate significantly higher energy generation with the solar tracker, especially under clear weather conditions.
