Step 1: What is your postcode and usage?

Please enter one of the following


Step 2: Select system size.

Solar systems are measured by how many Watts (W) and/or Kilowatts (kW) of electricity they produce. The larger the system, the more energy it will produce.

    How are the estimated savings calculated?

    This calculator uses the following generic assumptions, which may not be applicable to your circumstances. The above estimated savings assume:

    • A single, net metered solar power system, north facing on 30 degree incline with no shading loss;
    • the estimated generation of the solar power system is in line with ORER published data and the REC Zone of your post code;
    • system production degrades at 0.5% per year;
    • 42% of your total electricity consumption will be of energy generated by the solar power system (not exceeding the usage amount you estimated);
    • your quarterly bill period is 91.25 days; and
    • a residential AGL energy plan with the following Feed in Tariff: $0.08 (Vic), $0.08 (NSW), $0.08 (SA), $0.08 (Qld), $0.08 (TAS).  Actual savings may vary and any premium applied by AGL in addition to a government's feed-in tariff may be subject to change.

    Terms and conditions

    * By using this calculator you acknowledge that all savings calculations are estimates only and based on the generic assumptions set out above and that your ability to achieve these savings is dependent on factors outside of AGL’s control such as the weather, your annual energy usage patterns and the availability of government incentive schemes.. You should seek advice regarding your own circumstances before deciding which solar power system is suitable for you.

    Step 3: What sort of roof do you have?

    A: Type of roof surface:

    Unfortunately installations cannot occur on slate, asbestos, decramastic or structurally unsound roofs.

    B: Roof aspect and space:

    Roof aspect: Please note that installations on a north facing roof aspect provide optimum output for your solar PV system. East or west facing roofs may result in slightly reduced outputs.

    Roof space: Please ensure you have adequate roof space to install your solar system - see the chart below for the approximate space required and the number of panels.

    System size Roof area required No. of panels
    1kW 6.5m² 4x250W
    1.5kW 9.9m² 6x250W
    2kW 13.2m² 8x250W
    3kW 19.8m² 12x250W
    4kW 26.4m² 16x250W
    5kW 33m² 20x250W

    Solar Panels should face North,
    North-East or North-West.

    It is ideal to have a North, North-East or North-West facing roof, if considering installing solar.

    In Australia the sun rises in the East, moving towards the North, and sets in the West.

    C: What is the pitch of your roof?

    The pitch of your roof is crucial to optimum solar output. Flat roofs will require tilt frames to pitch the panels at the right angle.

    Step 4: What sort of switchboard do you have?

    Please select the type of switch board you have:

    Step 5: Solar rebate.

    Eligibility: Have you received a solar rebate before?

    Federal Government solar subsidies are only available once per Australian residence.

    Step 6: Enter your details.

    By providing your phone number an AGL solar consultant will call to discuss your needs, help you understand some important factors in choosing your system and show you the benefits of choosing AGL.
