Renewable Energy | Solar Power Mobile Charger Kit (Assembled), 100% Tested

Abstract

As the world increasingly shifts towards sustainable energy solutions, harnessing solar power for everyday applications is crucial. This project presents a mini solar mobile charger that utilizes a small 6V, 100mA solar panel to charge mobile devices. The system incorporates reverse power protection using a diode and features a charging module to enable USB charging.

This solar mobile charger captures sunlight and converts it into electrical energy. The solar panel generates a voltage of 6V under optimal sunlight conditions. The output is directed through a diode to prevent any reverse flow of current, ensuring that the battery does not discharge back into the solar panel during low-light conditions.

  1. Solar Energy Collection: The solar panel absorbs sunlight and generates DC electricity.
  2. Reverse Power Protection: A diode is placed in series with the solar panel output to prevent reverse current flow, protecting the panel and maintaining charge.
  3. Charging Module: The output is connected to a charging module that regulates the voltage and allows for USB charging of mobile devices.
  4. Output: Users can connect their mobile devices via USB to charge, making this a convenient solution for portable energy needs.
