On a $450 quarterly bill, that could save roughly $600–800 a year. Tarneit ranks 35th of the 38 Melbourne suburbs we've modelled for solar output, but the spread across Melbourne is only 3%: your roof's direction and shade matter far more than your postcode.

These figures use satellite and weather data for Tarneit from 2005 to 2023 and already allow for heat, wiring and inverter losses. They don't know your roof: shade, pitch and the faces available decide the real number, which is what the site visit checks. Try the roof calculator for your own direction and pitch.
