Utilization of Solar Cells on Power Bank with Automatic System Based on Arduino Nano Microcontroller

Introduction

The increasing demand for portable electronic devices and mobility has led to a significant growth in the use of power banks to charge our devices on the go. However, traditional power banks rely on non-renewable energy sources, which can harm the environment and contribute to climate change. In this study, we aim to develop a solar cell utilization tool on a power bank with an automatic system based on Arduino Nano microcontroller, providing a sustainable and environmentally friendly charging solution.

Background

The use of solar cells as a source of power has been gaining popularity in recent years due to its renewable and sustainable nature. Solar cells convert sunlight into electrical energy, making them an ideal choice for powering devices. However, the output of solar cells can be affected by various factors such as sunlight intensity, temperature, and angle of incidence. In this project, we aim to design a power bank that uses solar panels as a source of power, as well as voltage control from solar cells to the battery.

Tool Design and Function

The power bank design uses a solar cell as the main source of electricity. The combination of six solar cells in parallel configuration allows the addition of currents, so that it is enough to meet the needs of charging batteries. The chosen solar cells can produce stable and efficient output, especially in good sunlight conditions. The automatic filling process on this power bank battery is facilitated by the use of relays controlled by the Arduino Nano microcontroller.

The microcontroller plays an important role in controlling the channel process. When the battery reaches a maximum voltage of 3.7 volts, the connected sensor will send a signal to the Arduino Nano to break the current from the solar cell through the relay. Thus, this system not only optimizes charging, but also protects batteries from overcharging which can reduce battery life.

Performance and Efficiency

Based on testing, this power bank with a capacity of 6000 mAh can be fully charged within 7 to 8 hours in conditions of bright sunlight intensity. This shows that the design and components used in this project are quite efficient and effective. The efficiency of the filling system is also influenced by the angle and position of the solar cell on the source of sunlight, so it is important to ensure the right orientation for the best results.

Benefits and Applications

The use of solar cells on this power bank not only provides environmentally friendly charging solutions, but also supports the use of renewable energy. With the increasing need for portable electronic devices and mobility, this diesel power bank is an attractive choice for users who want to reduce dependence on conventional energy sources.

Further development in this system can include additional features such as charging indicators, long-distance monitoring systems, or integration with mobile applications to monitor the status of charging and equipment performance. This will increase user use and comfort value in utilizing this tool.

Conclusion

In conclusion, the utilization of solar cells on power banks with automatic systems based on Arduino Nano microcontroller provides a significant contribution in the development of renewable energy technology and innovative charging solutions. This project demonstrates the potential of solar cells as a sustainable source of power for portable electronic devices. With further development and improvement, this system can become a viable alternative to traditional power banks, reducing our reliance on non-renewable energy sources and promoting a more sustainable future.
