DIY Solar Panel 1V 80mA 0.08W Polycrystalline Epoxy Photovoltaic Cell 30x25mm

This epoxy solar panel is a practical starting point for anyone experimenting with small-scale photovoltaic power. With a polycrystalline cell delivering 1V at 80mA (0.08W) under full sun, it is designed to power small DC motors, charge low-voltage batteries, or act as a learning tool for solar energy basics. Its compact 30x25mm size and lightweight 0.01kg build make it easy to integrate into breadboard circuits, small models, or portable charging boards. The epoxy encapsulation offers basic protection against dust and moisture, extending its use in outdoor or educational settings.

Features and Construction

The panel is built around a polycrystalline silicon cell that balances cost and efficiency for low-power applications. Its epoxy coating shields the cell while keeping the unit thin and light.

Material and Build

Polycrystalline silicon forms the heart of the panel, known for its reliable performance under full sunlight. The epoxy resin layer seals the cell on the front, providing a smooth, easy-to-clean surface that helps maintain output over time.

Size and Practical Fit

At just 30 x 25mm and 0.01kg, this module fits into tight spaces where larger panels cannot go. It can be glued onto small enclosures, mounted on model vehicles, or used in science projects where space is at a premium.

Uses and Placement

This panel is suited for low-power tasks where a few hundred milliwatts are enough. Typical uses include trickle-charging small batteries or driving toy motors.

Event or Professional Use

Makers and educators can use it in workshops or classroom demos to teach solar cell operation, voltage-current relationships, and basic circuit design. Its low cost allows for multiple units in parallel or series experiments.

Everyday Home Use

Hobbyists can power a small fan, LED lights, or a simple solar charger for low-drain devices. With the right circuit, it can maintain a small battery during daylight hours.

Benefits and Buying Value

This panel offers a no-fuss entry into solar power without requiring a large financial or space commitment.

Reuse and Low Maintenance

Once installed, the epoxy panel needs no maintenance beyond occasional cleaning. Its solid construction means it can be reused across multiple projects if handled carefully.

Why Choose This Product

If you need a verified 1V, 80mA solar source in a compact footprint, this panel delivers those exact specs. The polycrystalline cell and epoxy build provide a durable, well-defined power component for your next DIY charger or motor driver circuit.
