Quick Answer
For RVs, the best mounting options for rigid solar panels involve securing them to the roof's structure, using sturdy racks or clamps with a wide base for stability, and ensuring adequate drainage and ventilation to prolong panel lifespan.
Roof Attachment Methods
For a rigid solar panel installation on an RV, you have three primary options for roof attachment: through-the-roof, rail-mounted, and adhesive-backed. Through-the-roof mounts provide a solid connection to the RV’s structure but may require drilling holes. Rail-mounted systems use a rail system along the roof’s edge, allowing for easy panel removal. Adhesive-backed options involve applying a strong adhesive to the panel’s back, securing it directly to the roof. Ensure the chosen method accounts for panel weight, wind loads, and roof material.
Panel Orientation and Angle
Panel orientation is crucial for optimal energy production. Mounting your rigid solar panels at an angle of 30-40 degrees ensures maximum energy output while allowing for snow to slide off. For a standard 60-cell panel, a 12-inch overhang is recommended to prevent water accumulation and improve airflow. This overhang also helps reduce the impact of wind loads and debris accumulation.
Additional Considerations
When choosing a mounting system for your rigid solar panels on an RV, consider the panel’s durability, efficiency, and lifespan. A sturdy mounting system can withstand harsh weather conditions, but it’s equally essential to select panels with a high power output and a long warranty (typically 25 years). Regular cleaning and inspections will also help maintain your system’s performance and extend its lifespan.
