Quick Answer
For optimal performance, pole-mounted solar installations should be installed at heights ranging from 8 to 12 feet, with the center of the solar array at or below a 30-degree angle from the horizontal. This allows for easy access and maintenance while reducing wind loading and shading issues.
Sizing the Pole
When selecting a pole for your solar installation, consider the weight of the solar array, mount, and any additional components such as a battery bank or inverter. A general rule of thumb is to use a pole that is at least 1/3 taller than the height of the solar array. For example, a 6-foot tall solar array would require a 9-foot tall pole.
Installation Height
To ensure maximum energy production, it’s essential to install the solar array at the optimal height. A height of 8 to 12 feet above the ground is ideal, as it allows for easy access and maintenance while minimizing wind loading and shading issues. The center of the solar array should be at or below a 30-degree angle from the horizontal to prevent snow accumulation and ensure proper water runoff.
Mounting and Securing
When mounting the solar array to the pole, use a sturdy and secure system that can withstand wind and weather conditions. Consider using a three-point mounting system, which consists of a top plate, a mid-plate, and a base plate. This system provides excellent stability and flexibility, allowing for easy adjustments and maintenance. Additionally, ensure that all bolts and screws are securely tightened to prevent any potential safety hazards.
