|Array Structure||Fixed: Ground Mount|
Trina monocrystalline silicon array, fixed ground-mount.
Monocrystalline panels convert sunlight at a high efficiency, and are often used where space is limited – such as on a large-scale tracking array.
This fixed ground-mount installation of Trina monocrystalline panels has the same configuration as the large-scale tracking arrays. Its performance can be compared to the trackers’ to confirm the gains contributed by the tracking system.
This fixed array is oriented in a position that will maximise its exposure to sunlight through the year. The panels are tilted at 20º from horizontal, close to Alice Springs’ angle of latitude. The array is directed due north.
Monocrystalline panels are manufactured from large silicon crystals sawn into single cells.
Solar Inception delivers complete photovoltaic power plants. They are distributors for Trina Solar, a photovoltaic manufacturing company based in China.

Notes on the Data
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 1A and 13: PV Module Discolouration
An orange discolouration of the majority of the PV modules on these arrays was noted in 2013. Investigation by the module manufacturer identified that the cause was the use of a particular back sheet material that on thermal and UV exposure has begun to breakdown and released the discolouring agent into the EVA. On these same arrays a several PV modules that utilized a different back sheet material have not been effected by this at all. Despite this discolouration no significant impact on the arrays performance has been noted to date. The module manufacturer did request to change out the effected PV modules, but for the benefit of the industry and to allow the progress of this issue to be observed over many years they kindly agreed to leave the majority of these PV Modules in place. The only PV modules that were changed out was the PV system now nominated as Site 1B, which was subsequently separated off as its own distinct array. Sites 1A and Site 13 retain the original PV modules.
