Premium ETFE Marine-Grade OEM mini Solar panels

IP67 Waterproof | 5+ Years Lifespan | Non-Yellowing
The choice for mission-critical devices.

  • Non-Yellowing: ETFE film withstands high UV exposure without degradation (unlike Epoxy).
  • Self-Cleaning Texture: Unique honeycomb surface reduces dust accumulation and light reflection.
  • Rigid Structure: Built on high-strength FR4 PCB (not flexible plastic) to prevent cell micro-cracks during installation.
  • Marine Ready: Corrosion-resistant materials suitable for saline environments (with optional edge sealing).
  • IP67: Completely sealed against salt mist and humidity. Non-stick surface washes clean with rain.

Engineered for the Toughest Deployments

The "5-Year" Reliability

Our ETFE modules utilize high-temperature vacuum lamination. The ETFE fluorine polymer surface creates a robust shield against salt mist, extreme heat (-40°C to +85°C), and chemical corrosion.

Superior Light Capture

The honeycomb texture traps low-angle light to boost efficiency, while its non-stick surface allows rain to wash away dirt, ensuring consistent output without maintenance.

FAQ (Frequently Asked Questions)

Q1: Are these ETFE panels flexible?

A: No. These specific modules are built on a Rigid FR4 Fiberglass backboard to ensure maximum durability and flat mounting on device housings. If you strictly require flexible ETFE panels (for curved surfaces), please contact our sales team for our separate “Semi-Flexible PCB” series.

A: The ETFE surface itself is impervious to salt and water. However, for full submersion or harsh marine wave impact, we strictly recommend adding our Edge Sealing or Full Potting Service to protect the FR4 layers from delamination over time.

A: We utilize premium Grade-A Monocrystalline PERC cells. These cells offer a high conversion efficiency of 21% – 23%, ensuring maximum power output in a small footprint. They provide excellent low-light performance for IoT devices at a much more competitive price point than back-contact cells.
