What is the primary function of a 2-axis tracker in solar energy systems?

The primary function of a 2-axis tracker in solar energy systems is to optimize sunlight capture. These tracking systems are designed to follow the sun's path throughout the day, adjusting both the tilt and orientation of the solar panels to maintain a perpendicular angle to sunlight as it moves across the sky. This capability allows the solar panels to receive the maximum amount of direct sunlight possible, significantly enhancing energy production compared to fixed systems.

By efficiently utilizing the available sunlight, 2-axis trackers can increase the total energy yield of solar installations. This is particularly beneficial during the early morning and late afternoon when the sun is at a lower angle to the horizon. Tracking systems thus play a crucial role in maximizing the efficiency of solar energy systems and providing a higher return on investment over time.
