Solar panel system prices in Australia vary with system size, panel and inverter quality, roof access, installation complexity and your location. Eligible households may receive an upfront discount through the federal Small-scale Renewable Energy Scheme, with the value depending on factors such as system size, postcode and installation date. Batteries, switchboard upgrades, monitoring and other electrical work can add to the quote. Compare itemised quotes from accredited installers and confirm current scheme details through the Clean Energy Regulator or energy.gov.au.
