Quick Answer
Solar trackers should be adjusted every 3 to 6 months to maintain optimal performance, depending on the quality of the tracker and the location's climate.
Tracking Mount Alignment
Adjusting solar trackers involves ensuring the tracking mount is properly aligned with the sun’s path. This typically requires a polar alignment, which involves adjusting the tracker’s north-south axis to match the Earth’s axis. This process usually takes 1-2 hours and is best done using a solar tracking alignment tool or a polar alignment app.
Seasonal Adjustments
Seasonal adjustments are necessary to account for changes in the sun’s path throughout the year. In the Northern Hemisphere, for example, the sun is higher in the sky during summer months and lower during winter months. Adjusting the tracker’s tilt and azimuth settings to match these seasonal changes can increase system efficiency by up to 10%. This process typically involves adjusting the tracker’s settings every 3-4 months, depending on the latitude and climate of the location.
Maintenance and Quality Control
Regular maintenance and quality control checks are essential to ensure optimal performance from solar trackers. This includes checking for any signs of wear or damage to the tracker’s mechanical components, as well as ensuring the tracker’s software is up-to-date and functioning properly. By performing regular adjustments and maintenance, solar tracker owners can maximize their system’s output and extend its lifespan.
