Solar Charging Controller Demo Kit with Arduino Nano + LED
Build Your Own Solar Charging Controller with Arduino Nano — A Live Energy Dashboard
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Harness the sun to charge a real 18650 battery while watching every milliamp flow across the OLED screen. This kit transforms a small 6V solar panel, an Arduino Nano, and a couple of sensor modules into a fully functional solar charge controller. As sun hits the panel, the TP4056 module safely charges the cell, and dual INA219 sensors feed live voltage, current, and power data to the display — turning abstract energy concepts into a tangible, real-time experiment.
What You'll Build
You’ll assemble a compact solar charging station that takes power from a 6V 2W panel, regulates it through a TP4056 lithium charger, and pushes detailed performance readings to a crisp 0.96-inch OLED. The display shows solar input power, battery charging current, and overall system health. It’s a complete energy monitoring demo that feels like a professional power meter, yet it’s built by your own hands on a breadboard.
What You'll Learn
- Wiring a solar panel through a blocking diode and into a TP4056 charging module safely
- Reading current and voltage with INA219 sensors using I²C communication
- Programming an Arduino Nano to calculate solar power and battery state on the fly
- Displaying real-time sensor data on an OLED screen with clean numeric formatting

Who This Kit Is For
Perfect for CBSE Class 11–12 students exploring renewable energy as part of their physics curriculum, or for ATL Tinkering Lab participants prototyping a solar-powered gadget. It’s equally at home in a B.Tech ECE first-year lab as a tidy introduction to I²C sensors and power management. Parents looking for a weekend STEM project with their child will find the clear build steps and visual feedback incredibly rewarding.
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?
Scan the QR code to launch the project-specific AI companion, or drop us a WhatsApp message. Either way, you’ll get step-by-step help that understands your exact circuit and code.
Can I use this kit outdoors in direct sunlight?
Absolutely. The 6V panel works best in bright sunlight, but keep the breadboard and electronics dry and shaded. For outdoor testing, just extend the panel wires.
Is the OLED display bright enough to read outdoors?
The 0.96-inch OLED has high contrast and works well under a shade, like under a small cardboard hood. Indoors or in semi-shade, the readings are crisp and easy to follow.
Do I need to solder anything?
No soldering required. All connections are made with the included M-M jumper wires on the 400-point breadboard, making the kit completely reusable and safe for beginners.
TP4056 charges 18650 from solar panel. INA219 monitors charge current. OLED shows solar power and battery.
