Quick Answer
Yes, adhesive mounting is a viable option for flexible solar panels on RVs, but it requires careful consideration of the surface material, weight capacity, and temperature range.
Choosing the Right Adhesive
When selecting an adhesive for mounting flexible solar panels on your RV, look for a product specifically designed for this purpose. Ensure it meets the following criteria: a high peel strength (at least 20 N/25mm), a temperature range compatible with the panel’s operating conditions (usually -20°C to 80°C), and a suitable surface preparation method for your RV’s material. Popular adhesive options include 3M VHB Tape or Loctite Epoxy.
Surface Preparation and Installation
Before applying the adhesive, clean the surface thoroughly to remove dirt, oils, and other contaminants. If your RV’s surface is smooth, apply a thin layer of adhesive to the panel and attach it to the surface, ensuring it’s centered and evenly spaced. For textured or irregular surfaces, use a specialized surface preparation method, such as applying a thin layer of a bonding primer or using a flexible adhesive with a textured backing. Apply gentle pressure to secure the panel in place, taking care not to exceed the recommended weight capacity.
Considerations and Limitations
Keep in mind that adhesive mounting may not be suitable for large or heavy solar panels, as the weight could compromise the adhesive’s strength or the surface material. Additionally, adhesive mounting may not be as aesthetically pleasing as other mounting methods, such as clamps or tracks. Regularly inspect the adhesive and panel for signs of wear or damage, and reapply the adhesive or replace the panel as needed to maintain optimal performance and longevity.
