When comparing a solar installer on the Sunshine Coast, check that the business and designer are appropriately licensed and that the installer is accredited under the Clean Energy Council’s current requirements. Obtain at least two or three itemised quotes covering panel and inverter models, system size, installation costs, warranties and after-sales support. Ask how the proposal accounts for your roof, shading, coastal conditions and local network requirements, and check independent reviews and references. Before signing, confirm key details with the installer and read the contract and warranty terms carefully.
