Solar Tracker
A mounting system that tilts solar panels to follow the sun's path across the sky, increasing energy production by 20-35% compared to fixed-tilt systems.
Why It Matters
While too expensive for most residential rooftops, single-axis trackers are standard for utility-scale solar farms and can make sense for large residential ground-mount systems.

Solar Azimuth
The compass direction of the sun. In the Northern Hemisphere, south-facing panels (180° azimuth) typically produce the most energy.
Tilt Angle
The angle of solar panels relative to horizontal. Optimal tilt often equals your latitude for year-round production.
Capacity Factor
The ratio of actual energy produced by a system to its maximum potential output. Solar typically has a 15-25% capacity factor.
