Solar Panels are most effective when they are pointed directly at the sun. Most solar parks and ground mounted solar panels use solar trackers.

The trackers are a mechanical system that adjusts the panels through the day.

Single-axis trackers allow the panels to follow the sun’s path from east to west. Single-axis trackers are commonly used in large solar parks.

Dual-axis solar trackers also adjust the panels for the height of the sun in the sky. In the winter months, the sun follows a lower ark across the sky.

Solar trackers allow panels to gather up to 45% more energy, so the extra cost of installation is justified in larger sized solar projects.
