Fixed solar panels are the workhorses of caravan solar systems. Unlike flexible panels that conform to curved surfaces, fixed panels offer superior efficiency, durability, and longevity that make them the top choice for serious Big Lappers planning extended trips around Australia.
Fixed panels deliver more power per square metre than their flexible counterparts, handle harsh Australian conditions better, and last significantly longer. The trade off is mounting complexity and reduced roof space flexibility, but for most caravanners, the performance benefits far outweigh these limitations.

☰ What’s In This Guide
What to Look for in Fixed Solar Panels
Choosing the right fixed solar panel depends on your specific caravan setup, power needs, and budget. Here’s what matters most when making your decision:
☐ Buyers Checklist
- Power Output: Match wattage to your daily power consumption. Most caravans need 300-800W total capacity depending on usage patterns.
- Efficiency Rating: Higher efficiency (18%+) means more power from limited roof space. Critical for smaller caravans.
- Cell Type: Monocrystalline offers better efficiency and longevity than polycrystalline, especially worth the premium for long term travel.
- Temperature Coefficient: Lower is better. Panels with -0.4%/°C or better maintain performance in Australian heat.
- Frame Construction: Anodised aluminium frames resist corrosion from coastal salt spray and harsh UV exposure.
- Warranty Terms: Look for 25 year performance warranties and 10+ year product warranties from reputable manufacturers.
- Mounting Compatibility: Ensure your chosen mounting system supports the panel dimensions and weight.
- Low Light Performance: Important for cloudy days and early morning/late afternoon charging in shaded campsites.
Tip
Calculate your roof space before buying. A standard caravan roof accommodates 4-6 panels of 100-200W each, but factor in roof vents, air conditioners, and antenna clearances.
