When comparing solar quotes on the Gold Coast, check that each quote uses the same assumptions, including system size, panel and inverter models, estimated annual generation and whether battery installation is included. Ask how the proposal accounts for roof orientation, shading, salt-air exposure and local network requirements, and confirm the installer is appropriately accredited and licensed. Review the itemised price, applicable STC discount, workmanship and product warranties, monitoring arrangements, and the retailer’s feed-in tariff and electricity rates rather than focusing only on the headline total. Before signing, check the contract, cancellation terms and after-sales support, and consider reviewing official guidance from energy.gov.au.
