Quantum 270L price (2026)
Modelled estimate, checked 23 September 2026: built from published before-rebate installed prices for this model, not Quantum's list price and not a quote. The STC discount is 15 certificates for a 2026 install in zone 3, which covers Sydney, Brisbane, Adelaide and Perth; Melbourne, Canberra and Hobart earn more, at the $40 clearing house cap. From 1 January 2027 the same system earns about one fifth fewer certificates, so the discount falls again.

Victoria includes the Solar Victoria rebate and Victorian Energy Upgrades; New South Wales includes the Energy Savings Scheme discount. Both are ranges because the amount depends on the system you replace and the installer. Solar Victoria Hot Water Rebate is not counted: Quantum is not on Solar Victoria's approved hot water product list, so this rebate cannot be claimed on one.
