Quick Answer
When racking placement in high wind areas, it's crucial to anchor panels securely, choose wind-resistant racking systems, and consider sloping the array to maximize stability and energy production.
Wind-Resistant Racking Systems
In high wind areas, select racking systems that meet or exceed local building codes and industry standards for wind resistance. Look for systems with high anchor forces, such as those with anchor forces of 1,000-1,500 pounds (450-680 kg) or more. These systems will ensure your panels stay securely in place during extreme weather conditions.
Sloping the Array for Maximum Stability
Sloping the solar array at an angle of 15-30 degrees can help to increase stability and energy production in high wind areas. This angle allows snow and debris to slide off easily and reduces the pressure exerted on the panels. Additionally, a sloped array can improve airflow under the panels, reducing the risk of damage from wind-driven debris.
Anchor Placement and Racking Pattern
When placing anchors, consider the racking pattern and the weight distribution of the panels. Use a staggered racking pattern to distribute the weight evenly and prevent panel shifts in high winds. Additionally, ensure that anchors are placed at least 12-18 inches (300-450 mm) from the edge of the roof and 12-18 inches apart in both directions to provide maximum stability and security.
