Polycrystalline Solar Panel 5V 30mA Portable Car Charger
Introducing the Polycrystalline Solar Panel 5V 30mA Portable Car Charger — a compact, versatile solar solution designed for hobbyists, students, and DIY enthusiasts. This lightweight panel captures sunlight and converts it into electricity to power small devices, charge tiny batteries, or illuminate DIY solar displays. Ideal for science projects and portable power on the go, it helps you observe the photovoltaic effect in a hands-on way while reducing reliance on grid power.
Built around reliable polycrystalline cells, this panel provides a simple, lightweight way to generate 5V of power at up to 30mA. It’s perfect for teaching, experiments, and small electronic applications where portable solar power is beneficial. Use it to power or charge small DC devices under sunlight or bright indoor lighting and scale up by combining panels if your project requires more power.
Benefits & Tips
- Great for small projects and science experiments to demonstrate how sunlight becomes electricity.
- Ideal for charging small DC batteries and powering microelectronics in portable setups.
- For proper sizing, pair panels with appropriate storage batteries using the guidance: 1.2V battery with a 2V–2.5V panel; 2.4V battery with a 3.5V–4V panel; 3.6V battery with a 5V–6V panel; 6V battery with a 7.5V–9V panel; 12V battery with a 15V–18V panel.
