Notes on the Data

  1. System Outage at Australia Day Long Weekend

    A breaker tripped at around 12.30pm on Friday, 26 January, likely due to high generation levels reached at this peak time on this high irradiance day. Connection was restored after the Australia Day long weekend at around 11.30am on Monday, 29 January but shortly tripped again.

    UPDATE 26-02-2018. The cause of this reoccurring issue has been identified and will be rectified. The solution requires the upgrading of a key distribution cable. This should be completed in the coming months.

  2. Connection Restored After Christmas/NY Period

    Arrays have been re-connected following the outage that disconnected multiple sites from Christmas day 2017. The outage is believed to have been triggered by the tripping of two circuit breakers in separate distribution boards, making the diagnosis initially elusive. The ability of the common circuit shared by these arrays to keep abreast with increasingly high current demands as new arrays are installed and generation conditions are high is presently being addressed. For the same reason, intermittent outages persisted in the summer of early 2018.

  3. System Outage at Christmas/NY Period

    A system outage was caused by a circuit breaker trip at approximately 2pm on a high generation day shortly after installation of a new array at the DKA Solar Centre. The outage commenced on 25 December continuing into the new year and is being addressed.

  4. System Outage for New Array Connection

    Sites 23 through to 37 experienced an outage today from 11:10 to 11:50. The outage was due to the local distribution board being temporarily being taken offline to allow for the connection of a new PV system.

  5. 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.

  6. Partial System Outage

    One of the major switchboards at the DKASC lost power yesterday 01/12/2016 at ~11:00 am. This isolated and shutdown array sites 23 through to 37 inclusive. The switchboard was re-energised at ~16:30 today (02/12/2016) and is again operating normally. Data for this period for these sites is lost.

Q: Why is it desirable to design solar modules to respond differently to different colours of light?

A: Sunlight consists of all the colours of the rainbow; white light may look "colourless" but actually includes every shade from red to yellow, green to purple and all the steps in between. While many solar modules are designed to maximise overall sunlight exposure/absorption but not take advantage of individual colours, some technologists are finding ways to optimise sunlight absorption on a colour-by-colour basis, combining different technologies that are each specialised to absorb a different component of sunlight, so that the module overall extracts as much power as possible from all received sunlight. Optimising absorption across the spectrum is tantamount to optimising absorption throughout the day, as well as throughout different sky conditions (such as blue-skied or clouded), since the relative intensities of individual colours in the sunlight change with those conditions.
