Flexible vs Rigid Solar Picker
Decide between flexible and rigid solar panels for your van based on roof, climate and priorities. Get a clear verdict and a wattage ballpark.
Will flexible panels always run hotter and age faster?
Usually yes. Bonded, zero-airflow installs trap heat, which accelerates degradation. If you go flexible, keep a small air gap where possible and avoid long, static baking in the sun.
Do I need a roof rack to use rigid panels?
No, but a rack or low-profile brackets help airflow and shading control. On corrugated roofs, brackets also solve uneven contact and water pooling.
How much more do flexible panels cost per watt?
Typically more than rigid modules. The gap varies by brand and region, but rigid panels generally offer better **€ per watt** and warranty terms.
Can I mix flexible and rigid on the same roof?
You can, but wiring, shading and mounting complexity go up. If mixing, keep arrays electrically similar and use the same MPPT per panel type.
How should I choose the final wattage?
Start from your **daily Wh/day** need, then check roof space. The picker’s range is a sanity check. Refine with solar sizing and MPPT limits before buying.
