Quick Answer
Mount solar panels on an RV roof using a sturdy, waterproof, and UV-resistant mounting system, ensuring panels are at least 12 inches away from the roof's edge for clearance, and securely fastened with screws or clips rated for the panel's weight.
Choosing the Right Mounting System
When selecting a mounting system for your RV, consider a system specifically designed for RVs, such as a track mount or roof rail mount. These systems provide flexibility, ease of installation, and adjustability to accommodate different panel sizes and roof types. Look for a system that can handle the weight of your solar panels (typically 15-20 pounds per square foot) and can be securely attached to your RV’s roof using screws or clips rated for the panel’s weight.
Roof Preparation and Clearance
Before installing solar panels on your RV roof, ensure it is structurally sound and free from any obstructions such as vents, antennas, or roof hatches. Leave at least 12 inches of clearance between the panels and the roof’s edge to prevent damage from wind, rain, or snow accumulation. Consider installing a roof sealant around the panel mounts to prevent water intrusion and ensure a watertight seal.
Electrical Integration
When integrating your solar system with your RV’s electrical system, ensure that the inverter is compatible with your RV’s battery bank and shore power setup. Install a DC-DC charger to charge your deep cycle batteries from the solar panels, and consider installing a remote battery monitor to track your battery state of charge and system performance. Use a high-quality inverter/charger that can handle the total system power output and provide a stable, clean sine wave output to protect your electrical appliances.
