A solar installer usually starts with your electricity use, roof, switchboard and energy goals, then recommends a system and provides a written quote. After you accept, the installer confirms the design, handles relevant grid-connection paperwork and schedules the installation. Accredited technicians mount the panels, install the inverter and any battery, connect the system to your switchboard, and test it. Your energy distributor may need to approve the connection before export to the grid begins, and your retailer can explain meter changes. Check the installer’s licences, insurance, warranties and accreditation before signing.
