  2. Site 1 tracker alignment

    Over the past few years, all but one of the Degerengie trackers at site 1A and 1B have been progressively failed. Mostly due to sensor and control board issues, though motor failures are also a factor on some trackers.

    As trackers had failed pointing in different directions, all the dysfunctional trackers have now been aligned to face north with a 10 degree tilt. This orientation is was chosen to allow self cleaning but minimize windage.

    The one functional tracker is located on site 1, and will be allowed to continue to track.

    - Site 1A dysfunctional tracker

    - Site 1B 2 x Failed PV inverters and dysfunctional trackers

    - Site 2 2 x Failed PV inverters and dysfunctional tracker

    - Site 5 AC cable fault

    - Site 22 1 x failed tracker

    - Site 33 1 x Failed PV inverter

    Remediation work is underway and each array will be returned to full operation as soon as possible.
