How much does solar power cost?
A quality 6.6 kW solar system in Australia typically costs $3,500–$7,000 installed after rebates, with 10 kW systems $7,500–$13,000 and a battery adding $8,000–$15,000.

What affects the price
— System size. More kilowatts means more panels and a bigger inverter — the core cost driver.
— Component quality. Budget, mid-range and premium panel/inverter tiers can swing a 6.6 kW quote by thousands.
— Roof type & storeys. Tile roofs, two-storey homes and complex multi-face layouts add installation time.
— Switchboard condition. Old switchboards often need an upgrade before solar can be connected, typically $800–$2,000.
— Battery storage. A household battery adds $8,000–$15,000 installed, offset in some states by rebates.
Tips before you post
— Use an installer accredited by Solar Accreditation Australia — it's required for the STC rebate and grid connection.
— Compare quotes on the specific panel and inverter models, not just the headline price per kilowatt.
— Check the inverter warranty (aim for 10 years) — inverters fail far more often than panels.
