How much space does a single axis solar tracker need?

On average, fixed-tilt systems will require four to five acres per MW and a single-axis tracking system will use about four to seven acres per MW 3. The good news is that even with the additional maintenance and space for single-axis solar trackers, it’s likely you will need fewer panels to meet your solar power demands.

How does a single axis tracker work?

Let’s dive right into the details beginning with the cost. Simply put, a single-axis tracker allows for more direct sunlight, producing more energy than a fixed-tilt rack. This makes the single-axis tracker more effective at absorbing energy as the system can track the sun’s movements throughout the day.

Does a single axis tracker produce more energy?

However, when comparing the two systems, the single-axis tracker is optimized to produce more energy, leading to a higher financial rate of return. While production increases with single-axis tracker systems can be significant, all the additional costs of installing and maintaining a tracker should also be considered.

Why is a single-axis tracker better than a fixed-tilt rack?

Simply put, a single-axis tracker allows for more direct sunlight, producing more energy than a fixed-tilt rack. This makes the single-axis tracker more effective at absorbing energy as the system can track the sun’s movements throughout the day. Trackers increase the production of a site by roughly 15% to 25%, compared to fixed-tilt systems 1.

Do single axis trackers need maintenance?

Single-axis tracking systems, however, require additional specialized professional maintenance, which tends to drive the cost up. The vegetation must be regularly trimmed for both kinds of systems as they may cause shading, or with single-axis trackers specifically, may interfere with their drivetrain.
