A solar quote should clearly show the panel and inverter brands, system size in kW, estimated annual generation, total price, and any battery or installation costs. Check whether the price includes the federal small-scale technology certificate (STC) discount, meter changes, monitoring, scaffolding and other possible extras. Compare several quotes on equipment quality, warranties, installer experience and expected output—not just the lowest figure. An accredited installer can explain the assumptions behind the estimate, while current rebate and eligibility details should be checked on the official energy.gov.au website.
