Look for a Gold Coast installer with current Clean Energy Council accreditation, appropriate licences and strong, independently verified reviews. Get at least three written quotes that clearly compare panel and inverter brands, system size, warranties, expected output, installation costs and any applicable incentives. Ask whether the installer will handle grid-connection paperwork and how they account for local roof conditions, shading and coastal exposure. Before signing, check the contract carefully and confirm key details with the installer, your electricity distributor and the relevant government or industry websites.
