SUNYIMA 10Pcs 5V 60mA Mini Polycrystalline Solar Panels 68mm x 37mm for DIY Projects

Compact solar power for DIY projects

Meet SUNYIMA’s 10-piece mini solar panel kit, designed for hobbyists, students, and makers who enjoy hands-on experimentation. Each panel measures 68 mm by 37 mm and delivers up to 5V at 60 mA under good lighting. These polycrystalline cells are paired with a durable epoxy resin AB adhesive and a glass-fiber base plate, creating a compact, sturdy power source for small projects. In full sun, you may see voltages rise above 5V, giving you a bit of headroom for low-power electronics.

This kit brings a tangible, tactile way to explore renewable energy concepts, from charging tiny batteries to powering microcontroller tests. The small footprint makes it easy to arrange panels on model roofs, DIY displays, or solar toy installations without sacrificing workspace or aesthetic integrity.

Key benefits and specs

• 10 polycrystalline panels in a single pack, ready for a variety of small-scale builds.
• Each panel rated at 5V and 60 mA, suitable for powering light sensors, LEDs, or microcontroller inputs in bright light.
• Compact size: 2.67" x 1.45" per panel, ideal for tight spaces on models, toys, and displays.
• Robust construction featuring epoxy resin AB glue and a PCB plus glass-fiber base plate for rigidity.
• Durable design aimed at outdoor activities and emergency preparedness, with power available even on overcast days for small loads.
• High conversion efficiency: up to 21.5–23.5% for polycrystalline cells, delivering usable energy from sunlight.

Real-world use and ideas

These panels are well suited for DIY solar-powered models, educational demos, and solar lighting experiments. They can complement toy projects, small art displays, or weather-station sensors that benefit from a gentle, renewable power source. While performance varies with light, the pack is designed to offer steady help for lightweight devices when the sun shines bright.

For makers, the kit provides a tangible starting point to explore power relationships, energy storage, and circuit design—without relying on bulky or expensive components. The combination of compact panels, a robust base, and straightforward assembly supports iterative prototyping and creative experimentation.

Usage tips

• Test panels in direct sunlight to gauge voltage and current under your load.
• Pair with a small battery or supercapacitor to smooth power delivery for LEDs or microcontrollers.
• Use in outdoor demonstrations to illustrate solar energy concepts to students or customers.
• Keep the epoxy glue and base plate intact to preserve panel alignment during handling.

Whether you’re building a solar-powered toy, a miniature display, or a classroom demo, SUNYIMA’s 10-pack offers an approachable, hands-on way to explore tiny-scale solar power.
