Detailed Description:

The 3V 150mA Solar Panel is the perfect starting point for anyone looking to power their small-scale electronics projects with clean, renewable energy. This compact mini epoxy solar module is a cost-effective and durable solution, built with high-efficiency polycrystalline silicon solar cells. Unlike glass-encapsulated panels, its robust epoxy resin coating provides excellent protection against environmental factors like moisture and dust, making it highly resistant to damage and ideal for both indoor and outdoor applications. With its small footprint and lightweight design, it is effortlessly integrated into a wide variety of builds, from portable gadgets to remote sensors.

Delivering a reliable output of 3V at a maximum current of 150mA under optimal sunlight, this panel is perfectly suited for low-power devices. It provides a peak power of approximately 0.45W, which is sufficient for directly powering small LEDs or motors, or for charging a small rechargeable battery with the addition of a charge controller circuit. Its ease of use is enhanced by the pre-soldered wires, allowing for quick and simple connections to your circuits. Whether you're a student building a science fair project, a hobbyist creating a solar-powered robot, or a maker looking for a sustainable power source for your Arduino or Raspberry Pi project, this mini solar panel offers a dependable and educational way to harness the power of the sun.

This 3V 150mA mini solar panel uses polycrystalline silicon cells with an epoxy resin surface, making it an affordable and durable choice for low-power DIY electronics. With a power output of ~0.45W, it's suitable for charging small batteries or powering microcontrollers, Arduino-based systems, small motors, and LED lights under direct sunlight.

Designed for educational, experimental, and renewable energy projects, this panel is easy to mount, safe for kids, and supports various solar learning experiments.
