Buying Guide: Key Purchase Considerations
- Flexibility vs. rigidity: Choose flexible panels for curved van roofs to maximize mounting area; rigid panels can offer durability and simpler mounting for flat surfaces.
- Weight constraints: Lighter panels reduce roof load and simplify installation, especially on smaller RVs or caravans.
- Cell technology: PERC and multi-busbar cells improve efficiency, particularly in low light or shaded conditions common on moving vehicles.
- Durability: ETFE or reinforced protective layers extend life in outdoor environments; consider IP ratings for weather exposure and wind or snow loads.
- System integration: Ensure compatibility with charge controllers and power stations; some kits include PWM or MC4-ready outputs for easy wiring.
- Space optimization: For limited roof area, prioritize higher wattage per square foot and consider kits with foldable or flexible designs to fit contours.
- Maintenance: Self-cleaning surfaces and abrasion resistance reduce cleaning frequency and keep efficiency high during use.
- Cost vs. performance: Higher efficiency panels offer better daily output in restricted spaces but can come at a premium. Balance upfront cost with expected daily energy needs.
- Installation considerations: Plan for secure mounting, cable routing, and protection against moisture; consider accessories like cable glands to seal entry points.
