4W 5V Polycrystalline Solar Panel with 3m DC5521 Cable

Product Overview

This 4W 5V polycrystalline solar panel provides a nearly square solar surface for compact lighting and electronics projects. The 172 x 175mm footprint suits layouts where a narrow strip-style panel is less convenient, while the approximately 3m lead gives room to route the connection away from the panel.

EVA lamination encloses the cells in a 2mm-thick module. The attached DC5521 plug connects to a matching socket in your project.

Key Features

• 4W rated power with a 5V operating voltage for matched small DC circuits.
• Polycrystalline silicon cells arranged in a compact, nearly square panel.
• Approximately 3m of cable helps separate the sunny panel position from the electronics.
• A DC5521 barrel plug avoids the need to terminate bare panel leads at the device end.

Compatibility & Notes

Check connector fit, polarity and the connected circuit's voltage and current requirements. A 3.7V battery requires an appropriate charging controller and protection circuit; the panel should not be wired directly to a bare cell. Confirm the complete circuit design before using it for garden lighting or other battery-powered projects.

Power varies with sunlight, orientation, temperature and load. Keep the panel clear of shading and secure the cable so that its connection is not pulled during use.
