What's the Point of a Dual-Axis Tracker?

When people think of solar energy, they usually envision stationary solar panels or ones with single-axis trackers. These are the familiar blue panels mounted on rooftops or the extensive rows of ground-mounted panels seen in solar farms. While going solar saves money, many don’t realize that dual-axis trackers are an option. They are as efficient, if not more so, than stationary panels and single-axis trackers.

Single-Axis vs. Dual-Axis: What’s the Difference?

As the name suggests, single-axis trackers move along one axis, typically from East to West. In contrast, dual-axis trackers can move along two axes, allowing solar panels to follow the sun from East to West and from North to South.

Are Dual-Axis Trackers Better?

While single-axis trackers can follow the sun's general movement from East to West and perform better than stationary panels, dual-axis trackers are even more precise and efficient. For example, the dual-axis tracker on the Smartflower ensures that its solar panels maintain an optimal 90° angle to the sun at all times. The result? A Smartflower can produce up to 40% more power than conventional solar systems! Additionally, if you live in an area where the sun's position changes with the seasons, a dual-axis tracking system will be more precise and help maximize your energy production.
