Current Output

Polycrystalline silicon array, single axis trackers.

Single axis trackers adjust the east-west orientation of an array, to increase its solar exposure through the day.

Solar panels are best able to generate electricity from light hitting their surface at a right angle. Adjusting their surface to follow the path of the sun will increase their electricity production.

These trackers are an “active” system, driven by motors according to a pre-programmed schedule. They follow the sun in 6 steps of 15 º before parking in a horizontal position at night and returning to face the east after sunset.

Using a program to angle the trackers will not necessarily always find the direction with the greatest amount of light like light sensitive trackers – however its single line of motion causes less wear on the motor. The tracker is powered from the array’s DC output.

Notes on the Data

  1. Faulty tracking units.

    At both sites 5 and 6 the single and dual axis tracking units have for several years been experiencing intermittent outages and component failures. These tracking units are no longer directly supported by any suppliers in Australia and replacement parts (control boards, actuator arms etc) have become difficult to source and thus several of the trackers at both sites are have failed or only operate intermittently. Continuing efforts are being made to repair these units but please note that the PV output of these two sites is negatively impacted by these technical issues.

  2. System Outage - Sites 4, 5, 17, 20, 22, 34 & 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.

  3. Site 5: Tracker Fault

    It was identified on 17/02/2012 that two of the Kyocera Solar Solar Forest 1-axis trackers were not tracking/moving. One tracker required replacement of main actuator arm the other tracker required new battery for controller. Both systems operational again by 30/04/2012
