0.5V Mini Polycrystalline Solar Cells, 100-Pack

Experiment with a small solar-powered model or circuit. These individual polycrystalline cells offer a 0.5V label in a hundred-piece pack. They are for makers learning how cell arrangements change a project's output.

• ✅ Build a small solar experiment — Individual cells provide a project-level energy source.
• ✅ Explore series and parallel arrangements — Separate cells let you design a matched array.
• ✅ Prepare several projects — A hundred pieces provide a larger component supply.
• ✅ Fit a small model surface — Compact cell dimensions suit miniature builds.

Plan the array around the measured output

Each cell is labelled 0.5V and 0.13W, with output dependent on sunlight and test conditions. Verify polarity and real performance before connecting a load or combining cells.

The blue cells are approximately 39 × 19 mm and need careful handling, interconnection and suitable encapsulation. This is not a complete panel or battery charger; additional circuitry may be required.
