Compact, efficiency solar panels designed for small electronics and DIY projects. Each panel delivers 1W at 5V and uses monocrystalline silicon cells and an ABS frame for a lightweight, durable module. Panels do not include energy storage or builtin charge control and are intended to be used with appropriate power management electronics when charging batteries or powering USB devices. Key benefits Efficient energy conversion: 20.5 percent cell efficiency maximizes output from a small surface area. Ready for small projects: 1W, 5V output is suited to microcontroller projects, sensor nodes, and lowpower USB devices when combined with proper charge management. Lightweight and compact: At approximately 148 x 45 x 2 mm and 46 g per panel, these panels are easy to mount, transport, and integrate into enclosures. Durable construction: Monocrystalline silicon cells and an ABS body provide stable performance for hobby and prototype use. Pack of two: Two identical panels are included, allowing independent use or combination for higher voltage or current with suitable wiring and regulation. Practical applications Remote sensor power: Provide continuous supplemental power for remote temperature, humidity, or environmental sensors when paired with a battery and charge controller. Hobby and prototyping: Power microcontroller projects such as Arduino and other lowpower development boards for outdoor or offgrid testing. Portable lighting and small USB accessories: Supply supplemental power to LED lighting, small fans, and USB accessories when used with appropriate power management circuitry. Specifications Item type: Solar Panel Material: Monocrystalline silicon, ABS Power: 1W (without storage function) Working voltage: 5V Efficiency: 20.5 percent Size: Approx. 148 x 45 x 2 mm (5.83 x 1.77 x 0.08 in) Weight: Approx. 46 g (1.6 oz) What is included 2 x Solar Panel Notes These panels do not include an internal battery or charge controller. Use a proper charge management circuit or regulator when charging batteries or powering sensitive electronics. For higher output combine the two panels in series or parallel as required, following correct wiring and voltage/current requirements for your application.
