Overview & Key Strengths
Why this solar panel
The EcoFlow 100W Flexible Solar Panel (ZMS331) weighs just 5.1 lb (2.3 kg) and flexes up to 258 degrees, making it purpose-built for curved camper van roofs, Airstream trailers, bimini boat tops, and off-grid cabin roofs.
Equipped with 23% efficiency monocrystalline silicon cells, integral bypass diodes to minimize partial-shading loss, and pre-molded metal grommets, it installs cleanly via structural adhesive or zip ties.
- Flexible monocrystalline panel, IP68, ~23% efficiency.
- Bends to vehicle/boat roof contours.
- Laminate rather than folding fabric.
- For semi-permanent camper installs.
