Solar Tracker
Mechanical structure that rotates modules to follow the sun, increasing daily energy yield 18–25% over fixed-tilt.
Single-axis trackers rotate modules around one north-south axis, following the sun east-to-west across the day. Dual-axis trackers add a second axis for seasonal tilt. Single-axis dominates utility-scale at 91% global share due to favourable economics (18–25% more generation for ~10% more capex vs fixed-tilt). Dual-axis remains niche due to a 60% capex premium.
