Search for local installers with current Clean Energy Council (CEC) accreditation, then check their reviews, ABN, experience and warranty terms. Obtain at least two or three itemised quotes covering panels, inverter, installation, switchboard work, monitoring, ongoing support and any government incentives. A CEC-accredited installer is generally required for small-scale technology certificates (STCs), but eligibility depends on the system and installation details. Before signing, verify the installer’s licence and contract, and check the relevant government or energy authority information for current incentive rules.
