Quick Answer
For areas with high snow loads, the best racking designs for solar panels are those that provide maximum strength, stability, and clearance, such as ballasted racking systems with heavy-duty feet and adjustable clamps for secure mounting.
Snow Load Considerations
When designing solar panel racking systems for areas with high snow loads, it’s essential to consider the weight and pressure snow can exert on the system. Snow loads can vary significantly depending on location, with some areas experiencing weights of up to 50 pounds per square foot. In such cases, ballasted racking systems are often preferred, as they distribute the weight of the snow evenly across the roof, reducing the risk of damage or collapse.
Designing for Snow Load Areas
To ensure a secure and stable solar panel racking system in areas with high snow loads, design the system with the following specifications in mind: use heavy-duty feet that can support at least 500 pounds per foot, and adjustable clamps that can be tightened to secure the panels in place. Additionally, consider using a minimum of 3 feet of clearance between the top of the racking system and the roof edge to prevent snow accumulation and ensure easy access for maintenance.
Recommended Racking Systems
Recommended racking systems for areas with high snow loads include the IronRidge S-Series and the Unirac SolarMount Ballasted Racking System. These systems are designed to withstand extreme snow loads and provide secure, adjustable mounting for solar panels. When selecting a racking system, ensure it meets the local building codes and regulations, and consult with a qualified solar installer to ensure a safe and efficient installation.
