3V Mini Solar Panels, One- to Four-Piece Packs

Add a tiny daylight source to a low-power experiment. These polycrystalline panels are labelled 3V and 0.15W each. They are for makers designing a small regulated circuit.

• ✅ Fit a miniature build — A small rectangle uses little mounting space.
• ✅ Choose the component quantity — One-, two- and four-panel packs are separate.
• ✅ Explore solar circuits — Individual panels provide a source for a matched experiment.

A small component rather than a complete lighting system

The 3V, 50 mA labels describe a light-dependent source. Match the real measured output to the load rather than expecting constant voltage or power in shade.

Each epoxy-faced panel is about 40 × 30 mm. A battery project needs an approved charging circuit; no battery, controller or complete light is confirmed as included.
