Do Solar Trackers Require More Frequent Maintenance Than Fixed?

Mechanical Wear and Tear

Solar trackers utilize a mechanical system to adjust the panels’ position to follow the sun. This mechanical movement leads to increased wear and tear on components, such as gears, bearings, and pivot points, which require more frequent lubrication and replacement. A general rule of thumb is to lubricate trackers every 6-12 months, depending on the manufacturer’s recommendations and environmental conditions.

Alignment and Calibration

Solar trackers also require periodic alignment and calibration to maintain optimal performance. This involves ensuring that the tracker’s axes are aligned with the sun’s path and that the panels are positioned at the correct angle. Misalignment can reduce energy production by up to 20%. It is recommended to check and adjust tracker alignment every 3-6 months, depending on the tracker’s design and the level of precision required.

Maintenance Scheduling and Record Keeping

To ensure that maintenance is performed on schedule, it is essential to keep accurate records of tracker maintenance, including lubrication, alignment, and calibration. This can be done using a maintenance log or a spreadsheet. It is also recommended to schedule maintenance during periods of low energy production, such as during the winter months, to minimize the impact on energy generation.
