Look for an installer with relevant electrical licences, solid local reviews and clear, itemised quotes covering panels, inverter, installation and warranties. A Clean Energy Council-accredited installer may be required for access to some government incentives, so check current requirements before signing. Ask who will perform the electrical work, whether the installer is properly licensed in your state or territory, and how after-sales support is handled. Compare several quotes and verify the business details, warranty terms and proposed system with the installer and relevant authorities.
