Quick Answer
Secure solar panels during high winds on an RV by using a sturdy roof rack system, panel clamps, and tie-downs rated for high winds, such as those from the RV Industry Association (RVIA) or the International Organization for Standardization (ISO).
Choosing the Right Roof Rack System
When upgrading your RV’s solar system, it’s essential to select a sturdy roof rack system that can securely hold the weight of your solar panels. Look for a system designed to withstand high winds and snow loads, such as those from reputable manufacturers like Renogy or Zamp Solar. A good rule of thumb is to ensure the roof rack system is rated for at least 30 pounds per square foot (psf) of snow load.
Panel Mounting and Tie-Downs
To prevent solar panels from shifting or becoming dislodged during high winds, use panel clamps and tie-downs specifically designed for RV solar systems. These clamps and tie-downs should be rated for high winds, such as those specified in the RVIA or ISO standards. For example, consider using 3/8-inch or 1/2-inch diameter tie-downs with a minimum of 5-foot long straps to secure the panels to the roof rack system.
Additional Considerations
When upgrading your RV’s solar system, consider additional factors that can affect panel security during high winds. These include the panel’s size, weight, and mounting configuration, as well as the roof’s material and design. Be sure to consult with a qualified solar installer or RV technician to ensure your system is properly designed and installed to withstand high winds and other environmental conditions.
