^{Discount offer is available to eligible residential customers in select postcodes in NSW, QLD, SA, and VIC that purchase a solar system through Echo Group Corporation Pty Ltd, a wholly owned subsidiary of EnergyAustralia. Your premises must be capable of having a solar system installed, including a compliant electricity meter and tariff type. Clause 11.3 of our quote to you will set out the terms that apply to your meter, which you are responsible for complying with.  We will confirm your eligibility during our quoting process. If eligible, a one-off $500 credit (incl. GST) will be deducted from the total cost of your solar system (including solar panels, inverter, and installation costs only), which will be calculated based on the final amount due on the date your solar system is installed. The cost of your solar system will vary depending on the brand and size of solar system you purchase, and any installation costs incurred . We may change or end this offer at any time. This credit is not transferable, or redeemable for cash.}
