0.5V 130mA Solar Panel Module – Mini Epoxy-Encapsulated Solar Cell for DIY Projects

As the largest natural energy source, the sun has always captured human interest; harnessing its energy to power small, portable devices is of great significance. A key component for converting sunlight into electrical energy is the solar cell—also known as a photovoltaic cell. This solid-state electronic device utilizes the photovoltaic effect to transform sunlight into electricity and serves as the foundation for many small-scale electronic projects.

This product is a portable solar panel featuring a compact design, making it ideal for use in various settings—such as while traveling, hiking, or in locations lacking access to the electrical grid. Rated at 0.5 volts with a current output of 130 milliamperes (mA), it provides a stable, independent power source for low-consumption equipment. The panel is constructed with a solar cell encapsulated in epoxy resin and backed by fiberglass, ensuring high durability and resistance to environmental conditions.

Measuring 53 x 18 mm, this 130 mA solar cell is well-suited for integration into devices such as radios, cameras, flashlights, and clocks. To achieve higher current or voltage, multiple small solar panels can be connected in series or parallel. This versatility offers great flexibility for DIY enthusiasts and those working with portable electronic equipment.

Beyond its economic benefits, the use of a mini solar panel helps reduce reliance on the electrical grid and contributes to a decrease in environmental pollutants. With a voltage of 0.5V and a current of 130mA, this product is an ideal choice for low-power devices as well as educational and scientific projects. Its compact design and the use of high-quality materials—such as epoxy resin and fiberglass—make this panel a durable and practical energy-supply solution.
