Quick Answer
To mount flexible solar panels on curved surfaces, use a flexible solar panel mounting system or an adhesive-backed foam tape that allows for expansion and contraction. The mounting system should be specifically designed for curved surfaces, such as a curved roof or a boat. Consider using a system with adjustable brackets for optimal panel positioning.
Choosing the Right Mounting System
When selecting a mounting system for curved surfaces, consider the panel’s wattage, surface area, and desired angle of installation. For larger curved surfaces, use a system with multiple brackets spaced evenly apart to ensure stability and even weight distribution. A recommended minimum spacing between brackets is 12 inches for panels up to 200 watts. For larger panels, increase the spacing to 18-24 inches.
Adhesive-Backed Foams for Smaller Surfaces
For smaller curved surfaces, such as RVs or campers, consider using adhesive-backed foam tapes specifically designed for solar panel mounting. These tapes allow for expansion and contraction, ensuring a secure and weather-tight seal. Choose a tape with a high peel strength (minimum 4 lbs/in) and a temperature range suitable for the panel’s operating conditions (typically -40°C to 85°C).
Preparing the Surface and Panel
Before installation, ensure the curved surface is clean, dry, and free of debris. Apply a thin layer of protective coating to the surface to prevent damage from the adhesive. Remove any protective film from the adhesive-backed foam tape and attach it to the solar panel, following the manufacturer’s instructions.
