Circuit Documentation

Summary of the Circuit

This circuit consists of a solar panel connected to a small-sized 12V battery. The solar panel is intended to charge the battery or provide power directly when there is sufficient sunlight. The circuit is straightforward, with the positive terminal of the solar panel connected to the positive terminal (VCC) of the battery, and the negative terminal of the solar panel connected to the ground (GND) terminal of the battery. There are no microcontrollers or other active components in this circuit.

Component List

Solar Panel

  • Description: A photovoltaic panel designed to convert sunlight into electrical energy.
  • Purpose: To generate electrical power for charging the 12V battery or directly powering a load during daylight conditions.
  • Pins:
    • + : Positive terminal
    • - : Negative terminal

12V Battery (Small Size)

  • Description: A rechargeable battery that stores electrical energy.
  • Purpose: To provide electrical power when the solar panel is not generating enough power, such as during the night or low light conditions.
  • Pins:
    • VCC : Positive terminal
    • GND : Ground terminal
