Key Assumptions and Baseline Data

  • The daily electricity consumption of a classic travel trailer varies significantly based on usage patterns and installed appliances.

    Note: Usage of high-power appliances (air conditioning, microwave, electric kettle) will substantially increase consumption.

  • Average Daily Consumption

    1.8 kWh

    conservative estimate

  • Peak Sun Hours

    4.5 hours

    average across most U.S. regions, accounting for seasonal variations

  • System Efficiency

    75%

    considering inverter losses, temperature, shading, dust, and other derating factors

Required Solar System Capacity Calculation

  • Required Capacity = 1800 Wh / (4.5 hours × 0.75) = 533 W
  • Recommended Capacity 600-800W 

(providing 25-50% margin for weather conditions and future expansion)

Number of Solar Panels

  • For 200W Panels:
    Number of Panels = 800W / 200W = 4 panels  
  • For 100W Panels:
    Number of Panels = 8000W / 100W ≈ 8 panels  

Optimal Panel Placement:

  • Primary Location: Unobstructed roof areas with maximum sun exposure
  • Mounting System: Low-profile fixed mounting with adequate ventilation gap (2-3 inches recommended)
  • Installation Method:Use aluminum brackets or stainless steel U-bolts secured to roof raftersImplement waterproof sealing with butyl tape and silicone sealantConsider tilt-adjustable brackets for seasonal optimization (15-30° adjustment)

This system design provides reliable off-grid power for typical travel trailer applications while maintaining safety margins for variable weather conditions and usage patterns. Professional installation is recommended to ensure optimal performance and compliance with relevant standards.
