Build Your Own Solar Home System Monitor with ESP8266 & ThingSpeak

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a compact dashboard that tells you exactly how much energy your solar panel harvested, how much your battery stored, and how much your load consumed—all updated hourly and visualized on the cloud. That’s what you’ll build with this kit: an IoT solar energy monitor that turns raw sensor data into actionable daily energy balance reports. Perfect for a school energy audit project, a hobbyist off-grid setup, or your next Smart India Hackathon prototype.

What You'll Build

You’ll assemble a working solar monitoring station that uses three INA219 sensors to simultaneously measure voltage and current from a 6V solar panel, a 4-cell 18650 battery bank, and any DC load you connect. The ESP8266 reads all three sensors via an I2C multiplexer, displays live power figures on a 0.96-inch OLED, and pushes hourly averages to a ThingSpeak channel. By the end, you’ll have a live energy dashboard accessible from any phone or laptop, plus a personal record of daily solar generation, storage efficiency, and consumption patterns.

What You'll Learn

• Interface multiple INA219 sensors through a TCA9548A I2C multiplexer to avoid address conflicts
• Program an ESP8266 to read voltage, current, and power from three points simultaneously
• Configure a ThingSpeak channel and write Arduino sketches that push data to the cloud
• Calculate real-time energy balance and daily net energy—solar harvested minus load consumed

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11–12 students working on physics investigatory projects on solar energy, B.Tech ECE/EEE undergraduates prototyping IoT power monitors, and teams participating in Smart India Hackathon or ATL Tinkering Lab challenges. If you’ve completed a basic Arduino course and want to dive into practical energy IoT, this intermediate kit bridges the gap between blinking LEDs and real-world monitoring systems.

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.
