The First Solar Tracker provides the highest mechanical availability and lowest O&M of any tracker in the industry. Our tracking technology has more than 50,000,000 hours of operation with a system availability of over 99.98%. Multiple third parties have verified the reliability of our tracker system and its components.
“We estimate a lifetime average mechanical availability …
of greater than 99.998% in each year of operation.”

First Solar also provides a data collection system that is incorporated into the tracker control system and reports the status at each individual row across the entire power plant. This built-in capability enhances system monitoring while further reducing cost and complexity.
