Compact 5V polysilicon solar module for lowpower outdoor applications Key benefits Converts sunlight into usable 5V power for small devices, enabling offgrid, maintenance operation for lowcurrent electronics. Small, gluebacked design simplifies installation on flat surfaces without bulky mounting hardware. Polysilicon cells provide stable, predictable output for hobby, sensor, and lighting projects. Why you need this module Provides a compact, dedicated solar source when mains power is unavailable or inconvenient. Keeps small batteries topped up and lowpower electronics operating longer between manual charges. Saves space and simplifies wiring where a fullsize panel would be impractical. Standout features Polysilicon solar cells for consistent photovoltaic performance. Micro mini size: 68 x 36 mm, fits into compact enclosures and narrow mounting locations. Output: 0.3 W nominal at a rated voltage of 5 V, suitable for lowcurrent loads. Gluebacked assembly for quick adhesive mounting to many surfaces. Specifications Cell material: polysilicon Dimensions: 68 x 36 mm Rated power: 0.3 W Rated voltage: 5 V Typical peak current: approximately 60 mA under strong sunlight (derived from power and voltage) Compatible applications and considerations Suitable for small electronics that accept a 5 V source or for charging small battery packs when used with an appropriate charge controller or protection circuit. Works well with microcontroller projects, LED lighting, lowpower sensors, and small telemetry or communication devices. For battery charging or longterm reliability, pair with a simple regulator, diode, or charge management circuit to protect batteries and electronics from overvoltage or reverse current. Practical use scenarios 1) Garden pathway LED: Mount the module on a pathway post to provide trickle power to a lowcurrent LED driver and extend operating time without running cables. 2) Outdoor sensor node: Power a remote temperature or motion sensor with this compact panel mounted to the enclosure, reducing the need for frequent battery replacement. 3) DIY electronics and education kits: Integrate into teaching projects or prototypes to demonstrate photovoltaic charging and to power small breadboard circuits. Installation tips Place the module where it receives direct sunlight for the majority of the day, oriented toward the sun for output. Use its gluebacked surface for temporary or semipermanent mounting; for longterm installations consider additional mechanical support. Add simple protection components such as a blocking diode and a small voltage regulator or charge controller when connecting to batteries or sensitive electronics. What this module is not It is intended for lowpower applications. It does not larger panels for current or power needs. It does not include embedded charge controllers or battery packs; additional circuitry may be required depending on the use case. This compact 68 x 36 mm, 0.3 W, 5 V polysilicon solar module is a practical choice for hobbyists, installers, and engineers who need a small, easytomount solar source for outdoor lowpower projects.
