Description
Fully automated two-axis solar tracking system
A fully automated dual-axis solar tracking system for 3 panels. The system uses GPS-controlled two-axis tracking to fully track the sun throughout the day, increasing solar electricity generation by up to 66%.
Dual-axis solar tracking system
Dual-axis or dual-axis solar tracking system with better than 0.5 degree accuracy and support structure for 3 solar panels measuring 1 m x 1.7 m and weighing up to 20 kg each. In total for a solar panel surface of 4.9 m². Suitable for photovoltaic (PV) panels.
The wind resistance is maximum 144 km/h with an average wind speed of 50 km/h for 10 minutes. On an annual basis, with the two-axis system, you can get up to 7% more energy compared to a single-axis system and up to 66% more energy compared to a fixed solar system. Anchor bolt and main pole are part of this solar tracking package.
Anti-shading software function for solar tracking system included.
Please check compatibility of solar panels with this tracking system. If your panels are larger, we strongly recommend that you consider adding a Bar Arm Bracket to ensure proper mounting.
