The latest solar tracker model, SunTrac+, features an integrated GPS receiver that automates the instrument setup process, enhancing both stability and functionality. This tracker is designed to automatically obtain position and time information from anywhere in the world, allowing it to complete the initial setup without the need for manual input. This eliminates the need for a computer during installation and operation, streamlining the user experience. The system’s working status is indicated by an audible buzzer, and continuous clock synchronization ensures consistent, high-precision positioning for accurate direct radiation measurement. The tracker is compatible with a wide range of direct radiation meters available on the market, offering exceptional versatility. The SunTrac+ uses advanced four-quadrant light balance sensors and solar trajectory tracking technologies to automatically follow the sun’s path, ensuring that sunlight is always perpendicular to the sensor for optimal measurement accuracy. The system consists of automatic tracking devices, sensors, and other components, which work together to track the sun’s movement. The tracker follows a method of automatic sun tracking from east to west, while also adjusting for solar declination angle. This feature ensures that the system provides real-time, continuous sun tracking throughout the day
