How we make money: WattsMyTariff is a free comparison tool. We may earn a referral commission from energy retailers when you switch via our links. This never affects the rates we show — every tariff is published directly from the retailer or the relevant state regulator. Data current as of July 2026. Always confirm current rates with your chosen retailer before switching.
Frequently asked questions
What is a solar feed-in tariff?
A feed-in tariff (FiT) is the rate your energy retailer pays you for solar electricity your panels generate but don't use in your home — the excess is exported to the grid. It's shown on your power bill as a credit, usually listed as "Solar feed-in" or "Solar credits". Rates are measured in cents per kilowatt-hour (¢/kWh).
How often do feed-in tariff rates change?
Most rate changes happen on 1 July each year, when the new financial year begins and regulators set updated benchmarks. Some retailers also adjust their offers mid-year. Queensland's regulated minimum is updated annually by the Queensland Competition Authority. Victoria removed its mandatory minimum in July 2025, so Victorian rates now vary significantly between retailers. We update our data every July and email subscribers when rates change.
Is switching energy retailers risky?
Switching retailers in Australia is straightforward and low-risk. Your electricity supply never actually interrupts — the physical wires don't change. The switch is purely administrative: your new retailer takes over your account. By law, your new retailer must give you at least 10 business days notice before your first bill, and you can cancel without penalty during a cooling-off period (usually 10 business days).
Should I just pick whoever pays the highest feed-in tariff?
Not necessarily. A high feed-in rate can sometimes come paired with higher usage charges or a higher daily supply charge. The best deal overall depends on your household's consumption patterns as well as your export rate. We recommend using the retailer's own comparison tool or the AER's Energy Made Easy (NSW, QLD, SA, ACT) or Victorian Energy Compare tools to compare full plan costs once you've identified better FiT rates here.
What's the difference between a flat and time-varying feed-in tariff?
A flat tariff pays the same rate for every kWh you export, regardless of time of day. A time-varying (or time-of-export) tariff pays different rates at different times — often very low or zero during the middle of the day when the grid is flooded with solar, and higher in the evening when demand peaks. Amber Electric, for example, pays wholesale spot prices which can be extremely high at peak times but also very low or negative during oversupply periods. If you have a battery, time-varying tariffs can be very lucrative.
How accurate are the earnings estimates?
The estimates are calculated using your system size, your state's average peak sun hours, and your chosen export percentage. They are indicative only — actual earnings will vary based on your roof orientation, panel degradation, shading, local weather, and the time of year. Think of the estimates as a comparison tool, not a guarantee. The gap between what you're currently earning and what you could earn is the most useful number — it's a fair apples-to-apples comparison.
