Floating Solar Panel Stabilization
A laboratory-scale floating photovoltaic stabilization system that actively compensates for wave-induced motion. Waves tilt a floating panel away from the sun and reduce the irradiance it collects, but a stabilizer also draws power. The project asks whether the extra electrical energy recovered can exceed the energy the stabilization consumes.

Objective
Quantify the net energy effect of active stabilization on a floating panel under wave disturbance, rather than only showing that the panel stays level.
Approach
The two-axis gimbal is driven by servos and commanded by an ESP32. An MPU-6050 IMU measures the panel's orientation, and a PID feedback controller drives the servos to cancel the measured tilt. The mechanical design was modelled in CAD and the embedded control software was written for the ESP32.
Testing and measurement
Prototype testing was iterative: PID gains were tuned, and the mechanical and control performance was refined between rounds. Measurements cover tilt deviation, stabilization response time, photovoltaic power output and servo energy consumption, compared to decide whether stabilization generated more energy than it used.
Status
The project is ongoing. Final results are not yet reported here.
