Search for local installers with demonstrated off-grid experience, rather than relying only on general solar reviews. Ask whether they can design the full system, including batteries, backup generation, switchboards and essential-load circuits, and confirm they hold the required state or territory electrical licences. Request itemised quotes covering site assessment, installation, monitoring, maintenance and call-out support, especially if you live remotely. You can also check relevant industry directories and verify the installer’s credentials with your state or territory electrical regulator before signing a contract.
