How payback works for a Whitby household
For an average WA household with a quarterly electricity bill around $ 420, a 6.6 kW system typically saves about $1,884 per year — combining bill offset (you import less) and feed-in credits (you export excess to the grid). Out-of-pocket cost after rebates is about $ 4,592, putting payback at 2.4 years.
That payback assumes a CEC-accredited tier-1 panel system (Trina, REC, JA Solar or similar) with a Sungrow or Fronius inverter. Budget gear is 15–20% cheaper but the warranty is half as long and the inverter usually needs replacing at year 8–10, so the lifetime numbers are worse.
