Product type and main benefit 2W 12V polycrystalline solar panel built with Class A polysilicon cells for consistent, efficient lowpower generation. Why you need it Provides a reliable, maintenance source of power for small 12V systems where grid power is unavailable or impractical. Ideal for maintaining battery charge and supplying continuous lowcurrent loads without drawing from mains power. Key features and what makes it stand out efficiency cells: Class A polysilicon maximizes output for the panel's compact size. Durable construction: Glasslaminated surface and a rigid frame improve weather resistance and longterm performance. Readytoinstall: Supplied with an aluminum frame for secure mounting and straightforward placement. Convenient connectivity: Includes a 3meter cable terminated with a 5521 DC plug for easy connection to controllers, batteries, or compatible devices. Performance specs: Rated at 2W / 12V with a working current range up to 0–166 mA and a shortcircuit current of 220 mA. Compatibility and practical use Designed for 12V systems and compatible with charge controllers, small battery banks, and devices that accept a 5521 DC input. Suitable for use where a small, steady solar source is needed rather than as a primary power source for loads. Typical applications (practical scenarios) Tricklecharging and maintaining 12V leadacid or AGM batteries in storage, seasonal vehicles, or backup systems. Powering lowconsumption outdoor equipment such as garden lights, weather stations, wireless sensors, or small monitoring cameras. Supplying supplemental power for DIY and offgrid electronics projects that require a compact 12V solar input. Installation and use tips Mount the panel on a stable, sunfacing surface using the included frame for output. Use a compatible charge controller when charging batteries to prevent overcharging. Route the included 3 m cable to your controller or device for a clean, reliable connection using the 5521 DC interface.
