How payback works for a Causeway household
For an average ACT household with a quarterly electricity bill around $ 433, a 6.6 kW system typically saves about $1,922 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 $ 5,476, putting payback at 2.8 years.
That payback assumes a tier-1 panel system on the Clean Energy Council's approved list (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.
