When built, it was the largest utility-scale solar photovoltaic plant in the southern hemisphere and remains one of the largest in Australia.
It is located about 10 km west of the Nyngan township, sitting on about 250 hectares of flat, rural land to the north of the Barrier Highway.
At Nyngan, about 1.36 million solar PV modules are installed on frames, supported by about 150,000 posts. These modules are at a fixed (non-tracking) tilt of 25 degrees, facing north. They are wired together in arrays, and connected to inverters which transform the DC current produced by the modules into AC current that feeds into the grid.
