5.5V Mini Solar Panel with Cable, Polycrystalline Module for DIY Battery Charging Projects

Compact polycrystalline solar panel module designed for DIY charging and small power projects. Rated at 5.5V and 291mA, the panel measures 150 mm x 86 mm and includes a 100 cm cable for easy connection and installation. Key benefits Ready to install: panel ships with a 100 cm cable for straightforward wiring to charge controllers, battery packs, or custom circuits. Reliable smallscale power: 5.5V at 291mA provides a stable lowpower source for sensing, lighting, and maintenance charging in daylight conditions. Spacesaving form factor: compact 150 mm x 86 mm size fits into hobby projects, enclosures, and portable setups where larger panels are impractical. Costeffective polycrystalline cells: durable and suitable for everyday DIY use while keeping the module affordable and practical. Simple to integrate: ideal for makers and technicians who need an offgrid power source without complex assembly. Specifications Output voltage: 5.5V Output current: 291mA Dimensions: 150 mm x 86 mm Cell type: polycrystalline solar cells Cable: 100 cm attached cable for direct wiring Intended use: DIY charger modules and small power applications How it solves common problems Eliminates need for mains power in small projects by providing a compact daylight power source. Reduces wiring complexity with an attached cable, saving time during prototyping and installation. Supports lowcurrent charging and powering tasks that do not require large or heavy panels. Compatibility and installation notes Use with appropriate charge controllers, voltage regulators, or diode protections as required by your battery chemistry and electronics. Suitable for lowpower 5V systems, microcontroller projects, LED indicators, sensors, and trickle charging of small battery packs when combined with proper circuitry. Mount in direct sunlight with an unobstructed view of the sky and an appropriate tilt for your location to maximize output. Protect against reverse discharge using a blocking diode or a controller that includes reverse current protection. Practical applications Remote sensor node: power an outdoor temperature or humidity sensor and its lowpower microcontroller during daylight hours, reducing battery swaps. DIY charging station: tricklecharge a small 5V battery pack or singlecell Liion via a compatible charge controller for hobby electronics and portable devices. Educational and hobby projects: integrate into school experiments, model boats, solar toys, LED garden accents, and other handson builds. What makes this module stand out Compact dimensions and integrated 100 cm cable make it easy to mount and connect without additional parts. Clear specifications for voltage and current simplify component selection and planning for project power budgets. Designed specifically for DIY charger use and small power applications where size, simplicity, and predictable output matter. Package includes One 150 mm x 86 mm polycrystalline solar panel module with 100 cm cable attached. Safety reminder Always use suitable charge management and protection circuitry when charging batteries. Observe polarity and secure connections before exposing the panel to sunlight.
