Current Output

Polycrystalline silicon array, experimental passive dual axis trackers.

The passive dual axis tracker that positions this array does not consume electricity.

Flat plates installed on different sides of the array transfer heat to hydraulic fluids in the tracker’s arms. The fluids will contract and expand in response to this heat, so that the array will be repositioned towards the heat source. This keeps the array oriented towards the sun through the day.

When the liquid cools after sunset, a spring will return the array towards the east.

Two experimental passive hydraulic arrays have been installed.

Note: this experimental technology has not functioned as expected since installation. The array typically faced away from the sun resulting in lower than expected outputs. The hydraulic trackers were also moving erratically and due to occupational health and safety reasons have now been fixed in place, i.e. they are not tracking.

Notes on the Data

  1. Monitoring Interruption for UPS Battery Replacement

    The disconnection and re-connection of the solar arrays and weather station equipment while a new site connection was being established prompted the already flattening UPS batteries which power the site’s energy meters to fail and require immediate replacement. Data recording was affected from approximately 2.30pm ACST, Monday 10 July to 4.00pm, Wednesday 12 July.

    Affects weather data for DKASC, Alice Springs

  2. Site 4: System Offline

    This array was taken offline in May 2013 and utilized for a separate research project for several years. The site shall be shortly re-established as a  fixed north facing array,

  3. System Outage - Sites 4, 5, 17, 20, 22, 34 and 35

    On the 5th June 2015, A Friday before a long weekend, seven individual PV systems at the DKASC were switched off by unknown persons and for unknown reasons. The outage was not noted until the following Tuesday when O&M staff returned to work and found the main circuit breakers for sites 4, 5, 17, 20, 22, 34 & 35. turned off. These systems were all turned back on again on the 9th March when the problem was detected.

  4. Site 4: Tracker Fault

    The experimental trcaker technology has not functioned as expected since installation. The array typically faced away from the sun resulting in lower than expected outputs. The hydraulic trackers were also moving erratically and due to occupational health and safety reasons have now been fixed in place, i.e. they are not tracking
