Features
  • 2.1W at 18V: Provides a compact solar input for low-power electronics and energy-harvesting systems.
  • Long rectangular footprint: The 247 × 44.5 mm shape makes efficient use of narrow mounting space.
  • Durable ETFE surface: Waterproof, UV-resistant, and scratch-resistant construction supports outdoor product integration.
  • Back-contact SMT construction: SPIC solar cells are mounted to the PCB with electrical contacts kept on the rear.
  • Polarity-marked solder pads: Two bare copper pads provide a straightforward connection point for custom wiring.
  • OEM-ready format: Contact LinkSolar about custom dimensions, outlines, lead wires, or connectors for production projects.

Product Overview

This 2.1W 18V mini solar panel is built for projects that need solar input in a long, narrow footprint. Measuring 247 × 44.5 mm, it combines a textured ETFE surface with SPIC back-contact solar cells SMT-mounted to a PCB. The slim rectangular format fits elongated housings and mounting areas that cannot accommodate a conventional square panel.

Compatibility & Notes

Use a charge controller or regulator suited to the connected device or battery; do not assume direct compatibility from the 18V rating alone. Output varies with sunlight intensity, angle, temperature, controller, battery, and overall system setup. Waterproof construction does not assign a specific IP rating or imply suitability for submersion. Protect the exposed PCB and solder pads from mechanical impact and excessive vibration in the finished assembly.
