Solar in the Mornington Peninsula and Frankston

The peninsula gets cool sea breezes and mild winters. Many homes are close to the bay or Bass Strait, where salt-mist rated panels and stainless or coated mounting hardware are worth specifying, and holiday homes often have very different summer and winter use.

The Mornington Peninsula and Frankston are on the United Energy network. Your distributor sets how much you can export and approves the connection; we apply for you before anything is ordered.

Salt air near the coast

Parts of Mornington are close to the water. Near the coast we specify panels certified for salt-mist exposure (IEC 61701) and corrosion-resistant mounting and fasteners, because standard fittings corrode faster in salt air.

What solar could save in Mornington

For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $600–800 a year, or $1,000–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.

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 are you after?
    When would you like it done?
    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)
