DIY Solar Panel Polycrystalline 1V80MA Epoxy Solar Cell for Low-Power Photovoltaic Projects

This small polycrystalline solar panel is designed for hobbyists, educators, and makers who need a compact photovoltaic power source for low-voltage DC applications. With an output of 1V and 80mA, it is well-suited for driving small motors, charging batteries, or demonstrating solar energy principles in classroom or workshop settings. The panel measures just 30 x 25mm and weighs 0.01kg, making it easy to incorporate into tight spaces or lightweight models.

Features and Construction

The solar panel uses polycrystalline silicon cells encapsulated in epoxy resin for basic protection. Its electrical ratings provide clear guidance for expected performance under standard sunlight.

Material and Build

The cell is made from polycrystalline silicon, a common photovoltaic material that offers a balance between efficiency and cost. An epoxy resin layer covers the cell to shield it from moisture and dust while allowing light to pass through. This construction is typical for small educational and DIY solar modules.

Size and Practical Fit

At only 30 x 25mm, this panel fits easily into small enclosures or onto breadboard prototypes. Its reference weight of 0.01kg means it adds negligible mass to any project, and the compact footprint allows multiple panels to be arranged in series or parallel if needed.

Uses and Placement

This solar cell is best used for low-power applications where space is limited. It can power small DC motors, charge NiMH or lithium-ion batteries (with appropriate regulation), or serve as a sensor in light-detection circuits.

Event or Professional Use

Teachers and workshop facilitators can use this panel to demonstrate photovoltaic principles in a hands-on manner. Its low current output is safe for student experiments, and the clear electrical ratings make it easy to calculate expected performance.

Everyday Home Use

Hobbyists working on solar-powered garden lights, small fans, or charging circuits for rechargeable batteries will find this panel useful. It can also be integrated into model buildings or solar-powered toys for added realism.

Benefits and Buying Value

This product offers an affordable entry point into solar energy projects. Its small size and clear specifications allow users to plan circuits accurately without guesswork.

Reuse and Low Maintenance

The epoxy encapsulation helps protect the cell from the elements, reducing the need for frequent cleaning or replacement in dry conditions. Simply wipe dust off the surface periodically to maintain light absorption.

Why Choose This Product

If you need a reliable, low-cost photovoltaic source for small DC motors or battery charging experiments, this panel provides well-defined electrical characteristics in a compact form factor. Its 1V80MA output is specifically suited for applications requiring a low voltage with modest current.
