Power Your Creativity with Renewable Energy
Are you a hobbyist, student, or engineer looking for a reliable power source for your small-scale electronics? The 3V 100mA Solar Panel is engineered to bridge the gap between complex solar technology and simple DIY application.
Unlike raw solar cells that are fragile and difficult to wire, this unit features a durable yellow plastic casing that protects the polycrystalline cells from impact during handling. It is specifically designed to withstand the rigors of classroom experiments and outdoor testing.
Why Choose This Solar Module?
- Zero Soldering Required: The integrated 2-pin Dupont connector (female/header style) allows you to plug this panel directly into standard breadboards, Arduino headers, or development boards.
- Optimized for Education (STEM): Ideal for teaching the principles of photovoltaics, renewable energy, and circuit building without the frustration of loose connections.
- Compact High Efficiency: Despite its small footprint, it efficiently converts direct sunlight into 3 Volts of power, enough to drive small DC motors, light up LEDs, or trickle charge capacitors and batteries.
Critical Usage Note for Best Performance
Sunlight Matters: Solar technology relies on UV intensity. This panel is designed for outdoor use under direct sunlight. It will produce minimal to no power under indoor household lights, fluorescent lamps, or on heavily cloudy days. Remove Protective Film: For maximum efficiency, please peel off the transparent plastic film covering the panel surface before your first use.

FAQ Section
FAQ Section
Q: Can I use this solar panel indoors with LED lights?
A: No. This is a photovoltaic panel that requires high-intensity UV radiation found in direct sunlight. Standard indoor lighting is too weak to generate the rated 3V/100mA output.
Q: Can this panel charge a mobile phone?
A: No, this panel outputs 3V at 100mA, which is insufficient for smartphones (which typically require 5V at 1000mA+). It is designed for small DIY projects, LEDs, micro-motors, or trickle-charging small 1.2V-2.4V battery packs.
Q: What is the polarity of the wires?
A: The connector follows standard color coding: Red is Positive (+) and Black is Negative (-). Please verify the pinout on your receiving board before connecting.
