|Array Structure||Fixed: Ground Mount|
Polycrystalline silicon array, fixed pole-mountThese fixed arrays have the same configuration as the single axis and dual axis pole mounted tracking arrays included in the Kyocera “Solar Forest” at the Solar Centre.
They are installed at the optimal orientation for a fixed array: due north and at a tilt close to Alice Spring’s angle of latitude. The output from these fixed arrays can be directly compared to the outputs from the single and dual axis tracking systems.

Notes on the Data
System Disconnection for Cabling Works
All arrays at the Solar Centre were disconnected from approximately 2.00pm to 3.00pm on Monday, 9 July 2018 in preparation for the cable between the main switchboard and distribution board being upgraded. Array sites #23-38 remained disconnected while the main feeder cable to these sites was replaced in subsequent days, but all systems were re-connected by early afternoon on Thursday, 12 July 2018.
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.

Site 14: Extended Disconnection - Cleaning
The array was cleaned along with all other arrays around the 4th to 6th December 2013. Each array was isolated during cleaning and turned back on afterwards. Unfortunately, the Site 14 (Polycrystalline Silicon, Kyocera) array was left off by the cleaning contractor and has been offline since 17:10 04/12/2013 until 16:40 13/12/2013.

Why can you see a mosaic-like pattern on each cell of a polycrystalline module?
A: Polycrystalline modules consist of cells that each contain multiple crystals of silicon. During the manufacturing process, the crystals grow right beside each other and the whole piece of silicon is sliced thinly when producing a photovoltaic cell, resulting in the cell having a mosaic-like cross section.
