Quick Answer
Position solar trackers 10-15 feet above the panels to minimize shading, and orient them at an angle of 30-40 degrees from south to maximize energy production. Ensure unobstructed views to the south for optimal performance. Install trackers on a level foundation with a slight tilt.
Choosing the Right Orientation
When positioning solar trackers, it’s essential to consider the sun’s path and the angle of incidence. In the northern hemisphere, the sun’s rays hit the ground at an angle of around 40-50 degrees during winter and 30-40 degrees during summer. Positioning trackers at an angle of 30-40 degrees from south will maximize energy production and minimize shading from nearby obstructions.
Foundation and Installation
A level foundation is crucial for optimal performance and longevity of the solar tracker system. Ensure the ground is compacted and graded to prevent settling or shifting over time. A slight tilt of 1-2 degrees can also help prevent water accumulation on the tracker’s surface. The tracker’s mounting system should be designed to withstand local wind and weather conditions.
Avoiding Shading and Obstructions
Position solar trackers at least 10-15 feet above the panels to minimize shading from nearby trees, buildings, or other obstructions. Consider the sun’s path during winter months when positioning the trackers, as even a small obstruction can significantly impact energy production during this time. Regular maintenance and monitoring can help identify and address any shading issues that may arise over time.
