Solar in South Gippsland and Bass Coast

This is one of the cloudier parts of Victoria in winter, but it still gets good output from spring to autumn. Coastal towns such as Inverloch, Cowes and San Remo need salt-mist rated panels and corrosion-resistant mounting near the water, and many holiday homes have very different summer and winter power use.

South Gippsland and Bass Coast are on the AusNet Services network.

Country properties

Sheds, pumps, long cable runs and rural supply lines all change how a system should be designed, and a battery only keeps the power on in an outage if it's set up for backup. See solar for rural properties and battery backup for outages.

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.

    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)
