What the data says

A north-facing kilowatt of panels makes between 1,326 and 1,646 kWh a year across the 429 places we've modelled, a spread of about 24%. That's far wider than the spread inside Melbourne. Output rises as you go north, away from the cloudier south-west and south coast.

Output isn't the whole story. Country homes often have bigger heating and cooling loads, sheds and pumps that can run in daylight, and more to gain from backup in outages, while rural supply lines can limit how much you export. Solar for rural properties.

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

    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)
    Step 5: your details

    Your details

    We'll call to book your free site visit, or outside about 100 km of Newport, a free assessment from your bill and roof photos. Your estimate and answers come with your details, so you won't have to explain it all again.

    How would you like to be contacted?

    Solar across Victoria: questions

    Where in Victoria is solar best?

    The north-west. In the model, Irymple makes 1,646 kWh per kW a year, about 15% more than Melbourne. Northern and north-western Victoria beat Melbourne comfortably; the Western District comes out lowest.

    Is solar worth it in country Victoria?

    Usually more than in Melbourne: more sun in the north and west, bigger roofs and sheds, higher heating and cooling loads, and more value from backup in outages. Export limits on rural lines are the main thing to plan around.

    Does Litmec do solar outside Melbourne?

    Yes. We sell, design and warrant solar and battery systems across Victoria. Start with a free assessment from your bill and roof photos; an accredited installer checks the site before installation.
