Design and deploy a customised Stand-alone Power System (SAPS) combining solar photovoltaic panels, advanced battery storage technology and back-up generation to power: Homestead Workshop
SPS Specifications – R-Series
101 10.5 kW of solar panels 25.2 kWh of battery storage 15 kVA of back-up diesel generation
Crop farmers, Tom and Victoria Brown, experienced power fluctuations or outages most weeks. Living towards the end of a distribution spur line of aging infrastructure, the Browns had power poles and wires running through their cropping paddocks. Power poles in paddocks present a range of safety issues including:
Farm machinery colliding with power poles, particularly during seeding and harvesting when machines operate at night, risking peoples’ safety, machinery damage, power pole damage and lengthy power outages
Pole top fires caused by dust on the wires, extreme weather events or bird collisions
Aerial sprayers clipping power lines.
Providing safe reliable power that met or exceeded the utility’s obligations under its charter.
Analysing the load profile, demands and usage requirements of the household and agri-business.
Mitigating the impact of a power outage on an end-of-grid customer by sizing the battery to be capable of providing 4 – 5 hours of back-up power, allowing the utility time to rectify an issue.
Locality Considerations including:
No requirement to travel across farm paddocks to limit bio-security risks
Ease of access for deployment and servicing
Safe distance from agricultural chemicals
Not inhibiting the movement of large farm machinery
Since the SAPS was installed in late 2019 the Browns have experienced a range of benefits:
Reliability and quality of power
Reduction from weekly power outages or interruptions to only two outages.
Improved quality and evenness of power flow.
Farm safety and land usage
The removal of poles and wires in the paddocks is:
Making it safer to operate farm machinery day and night.
Removing the costly impacts associated with farm machinery colliding with poles, including lengthy power outages.
Allowing the Browns to maximise the usage of their land.
Removing the possibility of a pole top fire igniting and spreading through their paddocks.
Making it significantly safer for aerial spraying as aircraft can fly low and stay low.
The reliability of SAPS is improving the Browns’ day-to-day lives, including:
Eliminating the prolonged unplanned outages as a result of issues occurring somewhere along the lengthy distribution spur line.
No longer needing to maintain a generator for back-up power.
Peace of mind when they are off the farm that the SAPS’ 24-hour remote monitoring service coupled with the back-up generator will ensure continuity of power.
“We no longer have to think about preparing the generator ahead of a storm, or the many other concerns that went with having power poles running through our paddocks.” – Victoria Brown
