Look for a Canberra installer with current Clean Energy Council accreditation, appropriate ACT electrical licensing and experience with local grid-connection requirements. Obtain at least three written quotes comparing panel and inverter brands, system design, warranties, inclusions, after-sales support and any extra work such as switchboard upgrades. Check the business’s reviews and complaints history, and confirm who will handle approvals and connection paperwork. Rebates and feed-in arrangements can change, so verify current information through the ACT Government, energy.gov.au and your electricity distributor before signing.
