About this project

Arduino Based System To Measure Solar Power

Objective: Develop an Arduino-based system to accurately measure and display solar power generation in real time.

Context: With India's growing emphasis on renewable energy, monitoring solar power output is crucial for optimizing installations and ensuring efficient energy use.

What you'll build: You'll interface voltage and current sensors (ACS712, INA219) with an Arduino UNO to collect solar panel data, compute power, and display results on an LCD or IoT dashboard. The system will be calibrated, tested under sunlight, and optionally log real-time data for analysis.

Deliverables: Functional measurement system, Arduino code, calibration report, and display/dashboard output.

Milestones

1. Sensor calibration & connection

5 marks 5d

Connect the solar panel and current/voltage sensors to the Arduino. Calibrate each sensor by comparing its readings to a known reference and document the calibration process and results. Submit wiring diagrams, photos of your setup, and a calibration table showing accuracy within acceptable error margins.

2. Data collection and power computation

5 marks 5d

Collect raw voltage and current data from the sensors under sunlight and compute real-time solar power (P=V×I) using Arduino code. Submit your code, a sample dataset (at least 10 readings), and a brief explanation of your computation method. Ensure computed power values are consistent with expected solar panel output.

3. Display output on screen or remotely

5 marks 5d

Display the measured voltage, current, and calculated power on an LCD screen or transmit them remotely (e.g., via serial or WiFi). Submit photos or screenshots of the displayed data, along with the relevant code. The output must update in real time and clearly show all three parameters.

4. Real-time logging (optional)

5 marks 5d

Implement real-time logging of voltage, current, and power data to an SD card or remote server. Submit a sample log file containing timestamped entries and the code used for logging. Ensure the log captures at least 30 minutes of continuous data without missing intervals.

5. Final system testing under sunlight

15 marks 5d

Test the complete system outdoors under direct sunlight. Document the test procedure, include photos of the setup in sunlight, and submit a summary table comparing measured power to the solar panel's rated output. The system must operate reliably, with consistent readings and no hardware or software failures during the test.

6. Hybrid Inverter With Solar Battery Charging

14 marks 5d

Integrate a hybrid inverter circuit and implement solar battery charging controlled by the Arduino. Submit circuit diagrams, code for charge control, and photos of the working setup. Demonstrate the system charging a battery from solar power and switching to inverter mode, with clear documentation of the transition and charging status.
