Arduino MPPT Solar Charger
Maximum power point tracking for a solar panel with Perturb & Observe on a boost converter.
Overview
A solar charge controller that keeps the panel at its maximum power point. An Arduino measures panel voltage and current, computes power, adjusts the boost converter's duty cycle each cycle with Perturb & Observe, and shows the operating point on an LCD.
The challenge
A panel's best operating voltage shifts with irradiance and temperature. A fixed duty cycle wastes energy, so the controller has to track the maximum power point continuously.
Our approach
Key capabilities
- Full P&O cycle: measure, compute power, perturb, compare
- Panel voltage and current sensing
- PWM control of the boost stage
- LCD readout of the operating point
- Proteus simulation and Fritzing wiring
Inside the project
Outcomes
- Working hardware prototype built and run on the bench
- Control loop validated in Proteus before the build
