Dual-axis solar tracking systems must maintain precise angular control across both azimuth and elevation axes while operating in varied environmental conditions. Field measurements show that well-implemented tracking can increase energy yield by up to 30% compared to fixed installations, though this benefit must be weighed against the system's own power consumption, which typically ranges from 0.1% to 0.5% of total energy production.

The engineering challenge lies in developing reliable mechanical systems that can achieve precise solar tracking while minimizing maintenance requirements and surviving decades of continuous outdoor operation.

This page brings together solutions from recent research—including rocking motion mechanisms on curved bases, three-legged mounts with linear actuator control, GNSS-based orientation systems, and mass-based autonomous positioning designs. These and other approaches focus on improving tracking accuracy and system longevity while reducing installation and maintenance costs.
