What to check in Cairns
Use these points before comparing quotes.
Rebate context: Federal solar STCs usually reduce the quoted solar price. No broad current state rebate is included here; check local, council, retailer, and VPP offers before signing.
Climate risk: Cyclones, high humidity, and corrosion risk make component quality important.
Roof design: A robust installation can be more valuable than a small upfront saving.
Tariff check: Check whether export limits or regional tariffs affect the value of surplus power.
