This project is a photovoltaic (PV) solar tracking controller.
The design target is a self-orienting dual-axis, scheduled, Arduino-based solar tracker model, demonstrating PV panel orientation for both Elevation and Azimuth angles (dual-axis). The Sun orientation is achieved through pre-calculated solar position data for a specific geographic location and time (scheduled).
Working under space, cost and time constraints, this prototype model is the follow-up project to SunTracker2 Revision 3.
In order to clearly understand, demonstrate and validate the sun tracking function, a 48 dual-color LED ring represents the horizon with north, sunrise and sunset indicators. A green indicator displays the suns daily movement over time. Two NEMA stepper motors align the solar panel model with the sun.
