Solar Panel Efficiency Monitor Kit – Real-Time Data Logging with Arduino

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

Turn a simple solar panel into a precision monitoring station that logs voltage, current, irradiance, and instant efficiency — all displayed on an OLED and saved to a microSD card. Designed for students and makers exploring renewable energy, this kit gives you the exact tools to measure how well a panel converts sunlight into electricity under real weather conditions.

What You'll Build

A compact, battery-powered Arduino monitor that connects to any small solar panel (not included). The INA219 reads voltage and current with 1% accuracy, the BH1750 captures sunlight intensity in lux, and the DS3231 timestamps every reading. Your code calculates panel efficiency (%) from power output versus irradiance on the panel area, then shows it live on the OLED and logs it to microSD for later analysis in Excel or Google Sheets.

What You'll Learn

• Integrate four I2C devices — INA219, BH1750, 0.96in OLED, DS3231 RTC — on a single Arduino bus without address conflicts
• Write Arduino sketches that read high-side current and bus voltage from the INA219, convert raw lux to irradiance in W/m², and compute panel efficiency
• Timestamp every measurement with the DS3231 real-time clock and store structured data on a microSD module for long-term outdoor logging
• Debug sensor noise with decoupling capacitors on the breadboard and understand why the 4.7kΩ pull-up resistors keep I2C signals clean across multiple devices

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11–12 students building a physics project on semiconductor photovoltaic cells, B.Tech ECE/EEE students working on microgrid or Smart India Hackathon prototypes, and ATL Tinkering Lab innovators who need a plug-and-play sensor suite for renewable energy experiments. It also fits perfectly into environmental monitoring assignments at NIT, VIT, or BITS where real-time data logging and efficiency analysis are part of the curriculum.

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.
