Which One Should You Buy?
Weekend warriors and casual campers should start with the Renogy 100W or HQST 100W panels. These entry-level options deliver reliable performance for occasional use while teaching you system fundamentals before potentially upgrading.
Full-time RVers and boondocking enthusiasts need the EcoFlow 400W or multiple RICH SOLAR 200W panels to support residential-style power consumption including refrigerators, air conditioning, and entertainment systems. The higher efficiency ratings become crucial when roof space limits your array size, making every square foot count toward energy independence. A typical Class A motorhome with 400-600 square feet of usable roof space can accommodate 1,200-2,000W of rigid panels when properly configured.
DIY installers benefit most from the Zamp Solar 170W with its pre-wired connections and integrated mounting hardware. The included components and clear documentation reduce installation errors.
Those prioritizing aesthetics should consider the RICH SOLAR Black Series panels, which blend seamlessly with dark RV roofs while maintaining respectable efficiency ratings. The all-black appearance eliminates the traditional blue-cell grid pattern that some find visually distracting on their recreational vehicles.
Safety & Common Mistakes
- Install DC-rated fuses within 18 inches of battery positive terminals to prevent catastrophic wire fires during short circuits
- Use 10AWG wire minimum for 100W panels over 20-foot runs; calculate voltage drop to stay under 3% loss
- Mount panels with stainless steel hardware and apply Dicor or Eternabond sealant to prevent roof leaks
- Ground panel frames to RV chassis using 8AWG copper wire to prevent static buildup and shock hazards
- Never connect or disconnect panels under load; cover panels or work at night to prevent dangerous arc flash
- Install bypass diodes to maintain output when partial shading occurs from trees or RV accessories
Disclaimer: Always follow manufacturer instructions and local electrical codes.
Installation Considerations
Rigid panel mounting requires careful planning to avoid compromising your RV’s structural integrity or creating water infiltration points.
Z-brackets provide the most secure attachment while allowing airflow beneath panels for cooling, which maintains efficiency during hot weather. Position panels to avoid shadows from air conditioners, satellite dishes, and vent covers that significantly reduce power output. Even a small shadow from a TV antenna can drop panel output by 50-75% due to how solar cells are wired internally.
Wire management becomes critical with rigid installations since cables remain permanently exposed to weather and UV radiation. Use liquid-tight conduit or UV-resistant wire loom to protect conductors, securing them every 18 inches to prevent wind damage. Route wiring through existing roof penetrations when possible, or install a dedicated solar entry gland that maintains your RV’s weather seal.
Consider tilt mount brackets for panels installed flat on your roof, allowing seasonal angle adjustments that increase winter production by 25-40% . While adding complexity and wind resistance, tilting capability proves invaluable for stationary camping where you can optimize panel orientation toward the sun’s path. Manual tilt mounts cost $50-100 per panel, while automatic tracking systems run $500-1,500 but can boost daily harvest by up to 45%.
System Sizing and Power Requirements
Calculate your daily power consumption before selecting panels. A typical RV uses 30-75 amp-hours (Ah) daily for basic needs.
LED lights consume 10-20W each, laptops draw 45-65W, and residential refrigerators require 100-150W continuous. Air conditioners represent the largest load at 1,200-2,000W, though soft-start devices can reduce startup surge by 70%. Microwave ovens pull 1,000-1,500W but only run briefly, making them manageable with adequate battery capacity.
Size your array to generate 120-150% of daily consumption to account for inefficiencies and cloudy days. A 400W system produces roughly 100-120Ah daily under good conditions, sufficient for conservative usage without air conditioning. Most full-timers install 600-1,200W to maintain comfort while boondocking, paired with 400-800Ah of lithium battery storage.
Charge Controller Selection
MPPT controllers extract 15-30% more power than PWM models by converting excess voltage into additional charging current.
The Victron SmartSolar series offers Bluetooth monitoring and programmable charging profiles for different battery chemistries. Size your controller at 125% of panel short-circuit current to prevent damage during edge-of-cloud events when irradiance briefly exceeds rated values. A 30A MPPT handles up to 400W at 12V or 800W at 24V, while 40A models support 520W/1,040W respectively.
Temperature compensation adjusts charging voltage based on battery temperature, preventing overcharging in summer and undercharging in winter. Remote temperature sensors should attach directly to battery terminals for accurate readings. Some controllers include battery voltage sense wires that compensate for voltage drop in charging cables, ensuring batteries receive proper charging voltage regardless of wire length.

FAQs
- How many rigid panels can my RV roof support? Most RV roofs safely support 3-5 pounds per square foot, meaning a typical 100W panel (16.5 lbs across 5.7 sq ft) adds minimal stress. Measure available space avoiding vents, AC units, and skylights, then calculate total weight including mounting hardware to stay within manufacturer specifications.
- What's the real-world daily output from a 200W rigid panel? What’s the real-world daily output from a 200W rigid panel? Expect 700-1,000 watt-hours daily from a 200W panel under typical conditions, accounting for angle losses, temperature derating, and atmospheric interference. Summer production peaks around 1,200Wh while winter drops to 400-600Wh depending on latitude and weather patterns.
- Should I wire panels in series or parallel? Series wiring increases voltage for longer wire runs and MPPT controller efficiency, but one shaded panel reduces the entire string’s output. Parallel maintains individual panel independence but requires heavier gauge wiring and combiners. Most RV systems benefit from series-parallel configurations balancing both approaches.
- How long do rigid panels actually last on RV roofs? Quality monocrystalline rigid panels maintain 80-90% rated output after 25 years, with many functioning beyond 40 years. Annual degradation averages 0.5% compared to flexible panels losing 2-3% yearly. Proper mounting and maintenance, including annual cleaning and inspection, maximizes operational lifespan.
- Do rigid panels work in cloudy conditions? Rigid panels generate 10-25% of rated capacity during overcast conditions, with monocrystalline cells performing better than polycrystalline in diffused light. High-efficiency panels like the EcoFlow 400W maintain usable output even in challenging weather, though extended cloudy periods require battery reserves or generator backup.
