A 6.6 kW north-facing solar system in Altona Meadows makes about 9,500 kWh a year: around 35 kWh a day in midsummer and 15 kWh a day in June. East or west-facing roofs make about 85% of that.

On a $450 quarterly bill, that could save roughly $600–800 a year. Altona Meadows ranks 16th 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.

Salt air near the bay

Your estimate

    How we worked this out

    We estimate your daily use from your bill and rates (about 30c per kWh and $1.10 a day supply unless you entered your own), then add typical loads for anything you ticked: about 6 kWh a day for an electric car, 4 for a pool pump and 6 for moving off gas.

    Solar output uses Melbourne's yearly average of about 3.5 kWh a day for each kW of panels. How much of it you use directly depends on who's home in the day; the rest charges a battery or is exported at about 4c per kWh.

    This is an indicative yearly average, not a quote. Roof direction, shading, your tariff and how you use power all change the result. An installer confirms every figure once they've seen your roof.

    Next: a few questions about your roof About a minute. Your answers and this estimate go to the installer, so you don't have to explain it all again.
    Step 4: your roof and plans

    A few quick taps so an installer knows what they're looking at. If you're not sure, pick "Not sure" or skip it.

    What kind of home is it?
    How many storeys? (installers need this for safety gear and access)
    What's the roof made of? (have a look from the street)
    Does anything shade the roof? (trees, a taller house next door, a chimney)
    Roughly when was the home built? (older homes often need switchboard work first)
    What matters most to you? (tick any)
    How are you thinking of paying? (Solar Victoria offers interest-free loans to eligible homes)
