Solar pricing in Adelaide
A typical 6.6 kW system in Adelaide retails for around $ 7,260 before rebates. After the federal STC rebate (1,386) and SA state programs (where applicable), most Adelaide households pay around $ 5,874 out of pocket.
Premium tier-1 panels (Trina, JA Solar, REC) with a Sungrow or Fronius inverter sit at the top of that range. Budget tier panels with a generic inverter sit at the bottom. We don't recommend the bottom of the range for Adelaide — premium panels are warranted for 25 years; budget gear often falls over at 10–15.
