Solar Irradiance Data Logger
Solar Irradiance Data Logger Kit – Log Solar Panel Yield and Irradiance with ESP8266
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Monitor your solar panel’s real performance with a self-contained data logger. The BH1750 measures irradiance while the INA219 captures voltage and current—every 5 minutes the ESP8266 timestamps the data, stores it on a microSD card, and then compiles a daily yield report that gets posted via WiFi. Perfect for analysing efficiency, proving a project hypothesis, or learning how solar energy systems behave under real sky conditions.
What You'll Build
A standalone IoT device that reads light intensity and panel power simultaneously. Data is logged locally with precise timestamps from the DS3231 RTC, displayed on the OLED for quick checks, and automatically reported each evening through your configured cloud endpoint—so you wake up to a clear summary of yesterday’s solar harvest.
What You'll Learn
- Interfacing I2C sensors (BH1750 light sensor, INA219 power monitor) with ESP8266
- Logging time-stamped CSV data to a microSD card for later analysis
- Using an RTC to maintain accurate time even during power cycles
- Aggregating sensor data and posting daily summaries via HTTP to a cloud platform

Who This Kit Is For
Ideal for CBSE Class 11–12 students creating a physics investigatory project on solar energy, B.Tech ECE/EEE students building an IoT-based energy monitor, Smart India Hackathon participants working on renewable energy solutions, and ATL Tinkering Lab mentors guiding a next-level sensor project. If you’re curious about how much power a panel really generates in Indian sunlight conditions, this kit gives you the hard data.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion walks you through each connection and code upload; if you still need a human, drop us a message on WhatsApp and we’ll help within hours.
Does this kit work with a solar panel of any rating?
The INA219 handles up to 26V and 3.2A, covering most small to medium panels used in school and college projects. Larger panels need an external shunt, which the code can be adapted for.
How do I view the daily yield report?
The ESP8266 posts the report to a cloud service like ThingSpeak or a custom webhook; you get a link or chart you can check from any browser. Detailed instructions for setting up the cloud endpoint are included.
Can I change the logging interval from 5 minutes?
Yes, the sketch is commented and adjustable—simply change a single value in the configuration section to log as fast as every few seconds or as slow as once an hour.
BH1750 and INA219 log irradiance and panel power every 5 minutes. ESP8266 posts daily yield report.
