Design and Implementation of Three-Axis Solar Tracking System with High Efficiency

The modern eras have seen different sources of renewable resources, which are naturally finding on a human timescale, such as sunlight, wind, tides, waves, and geothermal heat sources. One such example is solar power. The challenge remains to maximize the capture of the rays from the sun for conversion into electricity. A solar panel receives the maximum sunlight when it is perpendicular to the sun's rays but, the sunlight direction changes regularly with changing time. A fixed solar panel has a fixed orientation to the sky and does not turn to follow the sun. So, the attached solar panel is not able to generate adequate power. The best efficiency of the majority of commercially available solar cells ranges between 10-20%. This percentage shows that there is a high improvement needed. This advanced system deliberates the design and construction of a prototype model for a solar tracking system that has three-axis freedom, which can follow the sunlight in different directions automatically. The proposed method presents the fabrication and installation of a solar panel mount with a multiple-axis solar tracking controller. When sunlight falls perpendicularly onto the solar panels to maximize the capture of the rays by pointing the solar panels towards the sun & following its path across the sky. This way, the maximum electricity generation is ensuring high efficiency. The efficiency can be increased by 25%.
