Quick Comparison

Buyer’s Notes

Real-world solar output typically reaches 75-85% of rated capacity in ideal conditions due to angle losses, temperature derating, and wiring resistance.

The 13.4% output loss per 30° angle deviation from perpendicular means morning and evening generation drops significantly without manual repositioning. Plan for 4-5 peak sun hours daily in summer, 2-3 hours in winter, with overcast days producing just 15-25% of rated output.

Match panel wattage to battery capacity using the 75-130W per 100Ah guideline: a 200Ah battery bank performs optimally with 150-260W of solar input, allowing full recharge in one sunny day while avoiding overcharge damage. Portable panels complement fixed roof installations by providing 50-100% additional capacity when parked, plus the flexibility to chase sun while your RV remains shaded.

Temperature coefficients become critical above 30°C ambient: standard panels lose 0.35-0.45% output per degree, meaning 20-25% power loss in 45°C desert conditions. Premium N-type monocrystalline cells with 0.25-0.27%/°C coefficients maintain 85% output in the same conditions, justifying higher upfront costs for southwestern boondockers through increased daily harvest.

Safety Considerations

• Never connect or disconnect MC4 connectors under load—the resulting arc can damage contacts and create fire hazards
• Secure panels against wind loads exceeding 30 mph using guy-lines or anchor stakes to prevent damage
• Use properly rated DC breakers: 15A for 200W systems, 25A for 400W, positioned within 18″ of battery bank
• Monitor charge controller temperature; units above 60°C indicate undersized components or poor ventilation
• Maintain 3-foot clearance from propane tanks and exhaust vents when positioning panels
• Use 10AWG wire minimum for 20A systems, 8AWG for 30A, keeping runs under 25 feet

Always cover panels or disconnect at the charge controller before handling connections to prevent electrical hazards.

Installation Tips

Position portable panels below window height to minimize wind loading and prevent view obstruction. A 200W panel presents approximately 15 square feet of sail area, generating 50+ pounds of lift force in 40 mph gusts.

Install charge controllers in shaded, ventilated spaces with 6 inches of clearance on all sides for proper heat dissipation. Controllers operating consistently above 60°C will derate output and shorten component lifespan. Consider adding a small 12V fan for controllers mounted in enclosed compartments.

Wire runs should maintain less than 3% voltage drop for optimal efficiency. This typically means 10AWG wire for 20A systems under 25 feet, or 8AWG for longer runs. Use marine-grade tinned copper wire and sealed connectors to prevent corrosion in humid environments.

Maintenance and Troubleshooting

Clean panels monthly with distilled water and a soft cloth to maintain optimal output. Dust and pollen can reduce efficiency by 5-10%, while bird droppings create hot spots that permanently damage cells if left untreated.

Check MC4 connectors quarterly for signs of arcing or corrosion. Loose connections increase resistance and generate heat, potentially melting connector housings. Apply dielectric grease to O-rings annually to maintain weatherproof seals.

Monitor daily harvest using your charge controller’s history function. A sudden 20% drop in production indicates potential shading issues, dirty panels, or failing connections. Gradual decline over years is normal—expect 0.5-0.8% annual degradation for quality panels.

FAQs

• Can I mix portable panels with my existing roof-mounted system? Yes, but connect them through separate charge controllers to avoid voltage mismatches. Different panel types, ages, or orientations should never share the same controller input as the lowest-performing panel limits the entire string. Use a battery combiner or DC distribution block to merge the outputs at the battery bank.
• Will a 200W panel run my RV air conditioner? No—a typical 13,500 BTU RV air conditioner draws 1,500W running and 3,000W starting, requiring 8-10 200W panels plus 400Ah+ of lithium batteries for practical operation. Portable panels work best for lights, fans, electronics, and 12V compressor fridges that draw 50-80Ah daily.
• How do CIGS flexible panels compare to monocrystalline in partial shade? CIGS thin-film technology maintains 60-70% output with partial shading versus 20-30% for monocrystalline panels due to their non-crystalline structure that doesn’t create blocking diodes between cells. This makes CIGS ideal for forest camping despite their lower 17-18% baseline efficiency compared to 20-24% for monocrystalline.
• What size portable panel do I need for a 12V refrigerator? A 12V compressor refrigerator typically consumes 60-80Ah per day, requiring 150-200W of solar panels to maintain battery charge while running other small loads. Factor in your location’s average sun hours: 200W works for 4-5 hour sun zones, while 300W is better for areas with only 3 hours of peak sun daily.
