Compact polycrystalline solar panel designed for small power projects and portable use. Solid construction and a slim profile make it easy to mount or carry. Note that the panel does not store power and must be used with a charge controller or regulator when charging batteries or powering electronics. Key features and specifications Item type: Solar panel Material: Polycrystalline silicon for stable performance and long service life Color: As pictures shown Size: Approx. 200 x 130 x 2 mm (7.87 x 5.11 x 0.07 in) Working voltage: 18 V Opencircuit voltage: 19 V Operating current: 0 to 230 mA (typical operating range) Shortcircuit current: 300 mA Adjustable angle feature to help optimize sun exposure and improve conversion efficiency Package contents: 1x Solar Panel Important: The product has no power storage function Benefits and why you may need this panel Compact and portable: Small footprint and low thickness make it suitable for tight spaces or mobile applications. Stable material: Polycrystalline silicon offers reliable output for lowcurrent loads and DIY projects. Simple integration: Suitable as a direct solar source for lowpower systems when used with appropriate regulators, controllers, or converters. Easy to position: Adjustable angle capability helps you capture more sunlight throughout the day. Typical use scenarios Offgrid sensor or monitoring systems: Power lowcurrent sensors, telemetry modules, or remote indicators where mains power is unavailable. Battery trickle charging with a controller: Provide a topping or trickle charge to small 12 V battery systems when combined with a suitable charge controller. Portable and outdoor devices: Supply power to USB converters, LED lighting with a regulator, or hobby electronics during camping or fieldwork (use a proper voltage regulator or converter as required). Installation and compatibility notes This panel produces up to about 18 V under load and up to 19 V opencircuit. Use a compatible charge controller, voltage regulator, or converter before connecting batteries or sensitive electronics. Designed for lowcurrent applications. Verify that the current and voltage ratings match your device or system requirements before use. The panel does not include storage, wiring accessories, or mounting hardware unless shown in the product images. This solar panel provides a compact and practical solar source for lowpower applications where a small, durable panel is required.
