The Project


CWR operates 24/7 and is part of a large group of Car Wash sites around Australia. Energy is now high on the agenda for all sites and MD, John Whiteside has used his Turramurra site to showcase the benefits of Solar Power.


The team at Energus worked closely with John to design a 10.92kWp solar system, using the space available. The solution comprises 10.92kWp solar PV system using JA solar panels and ABB inverter. John has also installed CarbonTRACK, a real-time energy monitoring system, further helping to maximise the use of Solar Power.

The Car Wash bill will be reduced by approx. 43% with the cost of a large part of their daytime usage now fixed for years to come.

As an engineering based company, Energus uses science & data coupled with industry leading modelling tools to help businesses understand the benefits of investing in solar energy. With over 70 years of combined experience within the solar industry, Energus has the experience to design solar systems that strike the balance between price, performance and reliability — thereby maximising the Return on Investment (ROI) of each system installed.


  • Fix day time electricity cost at $0.06/kWh for the next 25 years
  • ~43% Annual bill reduction
  • Simple Pay Back ~3.6 Years
  • Return on Investment (ROI) in Year 1 ~ 27.6 %
