6V 2W Solar Panel for DIY and IoT Projects

The 6V 2W solar panel is a compact monocrystalline photovoltaic module designed for low-power electronics projects. It provides a reliable 6-volt output at up to 2 watts, making it ideal for charging batteries or powering microcontrollers like Arduino and ESP32. With its sturdy construction and pre-soldered leads, integration into your next prototype is straightforward.

Key Specifications

What You Can Build With This

• Solar-powered weather station using ESP8266 or Arduino Nano
• Battery charger for 3.7V Li-ion cells via TP4056 module
• Automatic garden watering system with moisture sensor and pump
• Portable phone charger with a boost converter module

Compatibility

This panel works with any microcontroller that accepts 5V–6V input, such as Arduino Uno, ESP32, or Raspberry Pi Pico. When paired with a Li-ion charger module (TP4056) and a boost converter, it can supply regulated 5V USB power. Ensure your project’s total current draw stays below 300mA for optimal performance in full sun.

Wiring Notes

Connect the red wire to the positive terminal and black to ground. For battery charging, use a dedicated charge controller; do not connect the panel directly to batteries. In low-light conditions, output may drop below 6V—test with a multimeter before connecting sensitive electronics.
