Abstract: The dual-axis solar tracker represents a significant advancement in solar energy technology, designed to optimize the solar energy capture by dynamically adjusting the position of photovoltaic (PV) panels. This system utilizes two degrees of freedom: azimuthal (horizontal) and elevational (vertical) adjustments, allowing the solar panels to follow the sun's trajectory across the sky. By aligning the panels perpendicular to the sun's rays throughout the day, the tracker can increase energy absorption by up to 25-45% compared to fixed installations.

This technology is particularly advantageous for applications requiring high energy yield and space efficiency, such as in residential solar power systems and large-scale solar farms. However, the complexity and cost of dual-axis trackers can be a consideration, as they involve more sophisticated mechanisms and maintenance compared to single-axis or fixed systems.
