Mini Solar Panel Kit 3.7V Small Panels for DIY Projects Battery Charging Flexible Compact Design

Five small solar panels designed for DIY projects and small charging tasks. Each panel measures 30x60mm and is intended for 3 7V charging applications. Compact, easy to integrate, and supplied as a set of five for flexible configurations. Key benefits Ready to use in hobby and prototype builds: small, uniform panels simplify mounting and wiring. Flexible power options: combine panels in series or parallel to increase voltage or current for specific needs. Saves time during design and testing: presized panels reduce the need for custom cutting or sourcing individual cells. Easy integration with charge controllers and regulators for safe battery charging and circuit power. Product features Quantity: 5 panels per set. Size: 30 x 60 mm each, compact footprint for tight spaces. Intended function: for 3 7V charging applications. Form factor: rigid small panels suitable for mounting on boards, frames, or enclosures. Application class: lowpower charging and supplemental power for small electronics and sensors. Compatibility and performance notes Suitable for small batteries and lowpower electronics when used with the correct charging or regulation circuitry. Can be wired in series to increase output voltage or in parallel to increase current; verify combined voltage and current against your charger or regulator specifications. Designed for hobby, educational, and prototype use rather than heavy industrial loads. Practical use scenarios Portable battery charger: build a compact solar charging module for a single 3 7V cell or small battery pack when paired with an appropriate charge controller. Remote sensor or IoT node: power or extend the runtime of microcontroller based sensors, data loggers, or wireless nodes in offgrid installations. Classroom and maker projects: assemble solar arrays for demonstrations, experiments, and student projects that teach basic solar power and circuit design. Installation tips Match combined panel voltage and current to your charger or regulator specifications before connecting to a battery. Include a blocking diode or appropriate charge controller to prevent reverse current at night. Secure panels in place and protect solder joints from moisture and mechanical stress for reliable operation. This set provides a convenient, compact option for smallscale solar projects where multiple identical panels are useful for tailoring voltage and current to the task.
