- What can 0.08W solar cells actually power?
- Small loads: a calculator, an LED, a sensor, or a trickle charge for a tiny battery. Ten of them together still make under 1W, so they will not charge a phone or run a motor for long.
- What voltage and current does each cell put out?
- About 2V open-circuit and 0.04A at peak, per the listing. Real output drops in shade, indoors, or at an angle to the sun.
- Do I need a charge controller?
- For a single cell feeding a small load, no. If you wire several into a battery, use a small controller or diode to stop the battery draining back through the cells.
- How big is each panel?
- About 40mm across, per the listed width. Check the space in your model or enclosure before ordering ten.
- Is this a good price?
- At $17.49 at Lowe's as of November 8, 2026, it is about $1.75 per cell, which is normal for hobby solar cells. Compare per-cell prices on other 10-packs before buying.
- What is in the box?
- Ten 2V, 0.08W polycrystalline solar cells. No frame, wires, controller or instructions are listed.
