Notes on the Data Terms & Conditions DKASC, Alice Springs DKP Microgrid / BESS Yulara Solar System NT Solar Resource

These notes and operational updates on data from the DKASC, Alice Springs and Yulara Solar System should be taken into consideration when analysing the data. They represent significant or interesting events that potentially impact the performance of systems installed at these sites. It is not an exhaustive list of every minor or short-term network or minor system outage. However, please contact us regarding any relevant other data issues.

For equivalent notes and updates on the NT Solar Resource stations, please download the metadata files which are kept up-to-date with relevant changes affecting the data.

  1. Data Outage - All Systems

    All site data from the 27th April 2022 until ~ 5pm on the 29th April 2022 was lost due to the outage of the site UPS. This issue was corrected and data restored at5pm on the 29th April 2022.

  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.

  3. Solfocus tracker back online

    One of the Solfocus trackers had been offline since last year due to a mechanical failure in the elevation drive, followed by a calibration issue. Both trackers are now back online and operating properly.

  8. Some system issues.

    The following sites have on going power issues due to a range of factors:

    - 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.

  9. Metering failure

    Circuit breaker supplying the metering equipment for sites 23-38 tripped off on Aug 19th and was discovered and turned back on on Aug 23rd. This resulted in a lack of generation data for these sites during this time but did not stop the sites from physically generating.

    Affects the following sources:

  10. Site 34 Winaico Outage

    The Winaico PV Array at Site 34 went off line on 2nd June 2021 due to a line AC line fault. This was rectified on the 15th June 2021.
