Quick Answer
To secure solar panels against high winds, use sturdy mounting systems, reinforced with hardware such as lag screws or anchor kits, and consider adding wind deflection or ballast systems. Some systems can withstand wind speeds of up to 100 mph. Proper installation and site assessment are crucial.
Securing Mounting Systems
When selecting a mounting system for solar panels, look for those with a sturdy base and reinforced hardware. Lag screw systems are commonly used and can provide sufficient strength, but anchor kits may be necessary for more extreme wind conditions. A general rule of thumb is to use at least 4-6 lag screws or 2-3 anchor kits per panel, spaced evenly across the mounting system. Ensure the mounting system is rated for the maximum wind speed expected at the installation site.
Wind Deflection and Ballast Systems
Wind deflection systems work by allowing the mounting system to flex or pivot in response to wind forces, reducing the stress on the panels and mounting hardware. These systems often involve a hinged or pivoting design. Ballast systems, on the other hand, use added weight to stabilize the mounting system and resist wind forces. A common approach is to use concrete or metal weights, typically 10-20 pounds per panel, strategically placed along the mounting system. When installing a wind deflection or ballast system, consider the specific wind pattern and direction at the installation site to ensure optimal performance.
