Quick Answer
Snow Guards play a crucial role in securing solar panel systems by preventing damage from heavy snowfall. They are designed to hold snow in place, reducing the risk of panels being dislodged or collapsed under the weight of accumulated snow. By minimizing damage, solar panel owners can ensure continuous energy production.
Understanding Solar Snow Load
Snow load can be a significant concern for solar panel systems, particularly in regions with heavy snowfall. The American Society of Civil Engineers (ASCE) recommends that solar panel systems designed for areas with heavy snow load should be capable of withstanding a minimum of 30 pounds per square foot (psf). In areas with extremely heavy snow load, such as Alaska or the Rocky Mountains, this number can be as high as 50 psf or more. To ensure compliance with local building codes and regulations, it is essential to consult with a structural engineer or experienced solar installer.
Installing Snow Guards on Solar Panels
Snow guards are typically installed on the roof, at the edge of the solar panel array. They are designed to be secure and durable, withstanding harsh weather conditions and extreme temperatures. The most common types of snow guards are clip-on and screw-on models. Clip-on models are attached to the existing roof structure using clips, while screw-on models are secured directly to the roof using screws. When selecting snow guards, consider factors such as snow load capacity, panel size, and roof material. Always follow the manufacturer’s instructions for installation and ensure that the snow guards are properly secured to the roof to prevent damage to the solar panel system.
