Buying Guide: Key Purchase Considerations
- Power output and voltage: Choose 400W units suitable for 12V or 24V systems; consider whether you need two panels to match a bank or a single high‑capacity unit for limited roof space.
- Efficiency and cell type: N‑Type cells (16BB) deliver higher efficiency and better performance in heat, reducing energy loss in sunny or warm conditions.
- Shading resilience: Anti‑shading or microcrack mitigation features help maintain output when trees or structures partially shade the panels.
- Weight and portability: Foldable or blanket designs save space for smaller vans, while rigid panels may offer greater durability for long excursions.
- Durability and weatherproofing: Look for IP ratings, ETFE coatings, and rugged frames to withstand road vibrations, rain, and dust.
- Installation ease: Pre‑drilled mounting holes, included cables, and plug‑and‑play connections speed up setup on a van roof or camp site.
- System compatibility: Ensure compatibility with your existing power station, battery bank, or inverter, including MC4 connectors, XT60, or Anderson‑style options.
- Warranty and service: Longer warranties and readily available replacement parts reduce total ownership costs over the life of the system.
