A feed-in tariff is the credit your electricity retailer applies when your solar system exports power to the grid. In Melbourne, available rates vary between retailers and plans, while Victoria’s Essential Services Commission publishes a minimum rate for eligible customers each year. Compare the tariff with daily supply charges, usage rates, contract conditions and any solar export limits, rather than choosing on the feed-in rate alone. Check the current Victorian Energy Compare service and your retailer’s fact sheet, and ask an accredited installer whether a battery or system size would change your likely exports.
