Features
  • 1W at 18V: Provides a compact solar input for low-power electronics and energy-harvesting systems.
  • Semicircular ring shape: Fits special-shaped layouts that cannot use a conventional rectangular panel.
  • Defined center opening: The 45 × 30 mm cutout leaves clearance for a central component, fixture, or enclosure feature.
  • 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 while electrical contacts remain on the rear.
  • OEM-ready format: Contact LinkSolar about custom dimensions, outlines, lead wires, or connectors for production projects.

Product Overview

This 1W 18V semicircular mini solar panel combines a distinctive half-ring footprint with a durable textured ETFE surface. The panel measures 153 × 73 mm overall and includes a centered 45 × 30 mm semicircular cutout, allowing a product design to preserve space around a central component or access opening. Genuine SunPower Maxeon IBC back-contact cells are SMT-mounted to the PCB, with two polarity-marked solder pads on the rear.

Compatibility & Notes

Check the 45 × 30 mm center opening against the intended enclosure or component before ordering. 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.
