ACTIVE SOLAR TRACKING SYSTEM

The AST-02&3 Active Solar Trackers consist of a 2-axis Gearbox with integrated Single Board Computer and Global Positioning System. They are designed to automatically point solar radiometers at the sun throughout the day.

The AST-02 has a single horizontal arm, The AST-03 type has dual horizontal arms.

The horizontal axis and the vertical axis are each rotated by a stepper motor, and harmonic gearhead with zero backlash. The Eye, on the horizontal arm, responds only to a narrow band of near-infrared radiation to improve sun seeking in difficult weather conditions.

The GPS signal is used to automatically configure the Tracker for geographic location and real local time. Whenever the sun is obscured (by clouds) the system defaults to open-loop passive tracking using GPS position information. Whenever the sun is detected by the Eye the system actively tracks the sun under closed-loop control.

The Tracker operates on 12VDC and has low power consumption to make it suitable for solar powered sites.

The image above shows the AST-03 Tracker with optional SA02 Shading Arm Assembly, and optional LS01 Levelling Stand.
