Gullen Solar Farm is a 10MW solar photovoltaic (PV) project, co-located with the existing Gullen Range Wind Farm in NSW. Locating the solar farm at the wind farm site minimises required infrastructure such as roads, power lines and telecommunications, meaning a reduction in environmental impact and project cost.

The solar farm will produce approximately 22,000 megawatt hours of clean renewable energy each year, enough energy to supply approximately 3,100 NSW homes. The operating life of the solar farm will be up to 30 years.
