On Grid Solar PV System Using Arduino Uno

Overview

Welcome to the comprehensive guide on creating an “On Grid Solar PV System” tailored for EEE final year students. This innovative project harnesses solar energy to power electrical loads, utilizing Arduino Uno as the main microcontroller for efficient system management.

Key Components

• Arduino Uno: The brain of the system, managing all operations and data processing.
• 12V Battery: Provides power storage for the system.
• 12V Solar Panel: Charges the battery using solar energy.
• Solar Inverter: Converts 12V DC from the battery to 220V AC, suitable for household appliances.
  • Input: 12V DC
  • Output: 220V AC
• 2-Channel Relay Module: Ensures seamless switching between main power line and inverter line.
  • Main Line On: Inverter line off
  • Main Line Off: Inverter line on
• Voltage Sensors: Monitor solar panel and battery voltage levels.
• Current Sensor: Measures the load current.
• I2C with LCD: Displays real-time data including voltage, current, and system status.

System Functionality

This On Grid Solar PV System is designed to provide a reliable alternative energy solution by integrating solar power with the existing electrical grid. The Arduino Uno microcontroller plays a crucial role in monitoring and controlling the entire system.

• Power Management: The 2-channel relay module ensures that when the main power line is active, the inverter line is switched off, and vice versa. This automatic switching optimizes energy usage and provides uninterrupted power supply.
• Voltage and Current Monitoring: Voltage sensors keep track of the solar panel and battery voltage levels, while the current sensor measures the load current. These readings are crucial for efficient energy management and are displayed on the LCD screen for easy monitoring.
• Real-Time Display: The I2C with LCD interface provides a user-friendly display of all system parameters, allowing users to monitor the performance and health of the solar PV system in real-time.

Benefits for EEE Students

Working on this project equips EEE students with practical experience in renewable energy systems, microcontroller programming, and electrical system design. Key learning outcomes include:

• Understanding Solar Energy Systems: Gain in-depth knowledge of solar PV systems and their integration with the electrical grid.
• Microcontroller Programming: Develop skills in programming the Arduino Uno for various control and monitoring tasks.
• Electrical Measurements and Monitoring: Learn to use sensors for accurate voltage and current measurements and display the data effectively.

Conclusion

The “On Grid Solar PV System” project offers an excellent opportunity for EEE final year students to explore the potential of renewable energy solutions.
