When comparing solar quotes in Melbourne, check the system size, panel and inverter brands, estimated annual generation, installation costs and warranty terms. Ask whether the quote includes design, electrical work, grid-connection paperwork and any likely extra costs for a tiled or multi-storey roof. Rebates and Small-scale Technology Certificate discounts can affect the price, but eligibility and savings depend on your circumstances and are ultimately determined under the applicable government rules. Consider quotes from CEC-accredited installers and verify the final proposal with the installer and your electricity distributor before signing.
