Nick and Mandy Chapman – Horizon Power customer


Condingup, 64 kilometres east of Esperance, Western Australia


Crop and livestock farmers Nick and Mandy Chapman were part of Horizon Power’s inaugural deployment of 17 stand-alone power systems (SAPS) as part of the utility’s upgrading of power infrastructure along a lengthy distribution spur line.

The Chapman’s, like many farming families, experienced the challenges which came with power interruptions and outages. Their generator was always on stand-by ahead of forecasted storms to ensure the essentials, such as water, could continue to be pumped to the house in the event of a lengthy power outage.

Having power poles and wires running through their paddocks presented a number of issues and hazards when cropping, 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
  • Pole top fires caused by:
    • dust on the wires
    • extreme weather events
    • bird collisions
  • Aerial sprayers clipping power lines.


Design and deploy a customised SAPS combining solar photovoltaic panels, advanced battery storage technology and back-up generation to power:

  • Homestead
  • Shearing shed
  • Workshop

Specifications: R-Series SAPS

  • 10.8 kW of solar panels
  • 25.2 kWh of battery storage
  • 15 kVA of back-up diesel generation
