The station was running a large, inefficient diesel generation system 24/7 for their power supply, the renewable off-grid installation goal is significantly reduce generator operation costs and provide increase power self sufficiency for the the remote site. Considerations included detailed load analysis under multiple occupation scenarios (Eg. Shearing) and understanding the most suitable solar and battery equipment locations given the large and complex power distribution network.
The system included robust system components with suitable tolerances for the harsh, hot and dusty conditions of the site. A diesel generator was incorporated into the system as a backup power source when required.

After the installation, fuel savings will achieve a return on investment in as little as 4 years. Additional benefits included massive reduction in onsite noise from the generator, and the need to transport large volumes of diesel to the site. The system requires minimal user maintenance, and has made the property far easier to manage and operate for the client.
