Gold Coast households should compare the system size, panel and inverter warranties, expected electricity use and several written quotes from accredited installers. Because the area is served by Energex, your installer should confirm network requirements, export limits and any approval needed before connecting the system. The federal Small-scale Renewable Energy Scheme may reduce the upfront price through certificates, but eligibility and the value offered can change. Feed-in tariffs also vary between retailers, so compare the full electricity plan rather than choosing on the tariff alone. An installer can assess your roof, shading and likely generation for your property.
