Beating the "Solar Tax": How to Master Midday Export Charges in 2026
Australia's grid is charging some solar owners to export power at midday. Here's what the "Solar Tax" actually costs, which states it applies to, and three practical strategies to make sure you're never caught paying it.
If you've looked at your energy bill recently, you might have spotted something new: Export Charges. Australia has started rolling out "two-way tariffs," a pricing system where sending your solar power back to the grid during the middle of the day can actually cost you a small fee, typically between 1 and 3 cents per kWh.
Where Is This Actually Happening?
It's worth being precise here, because this varies a lot by state. Two-way pricing is currently live in New South Wales and South Australia. Victoria's decision is expected around 2026, once the Australian Energy Market Commission finalises proposals from local distributors. Queensland's proposals were knocked back by the AER in 2024 and remain in revision.
So if you're in NSW or SA, this is real and active now. If you're in Victoria or Queensland, it's coming but you still have time to prepare. Use our Location Guide to see exactly what applies in your area.
The "Solar Tax" Is Not That Scary (But It Is a Signal)
For a typical 5 kW residential solar owner in NSW on Ausgrid's network, the net annual cost of the two-way tariff works out to around $6.60 per year, about 13 cents a week. The tariff also includes a free export threshold, meaning you can send a certain amount of power back to the grid at no charge before any fees apply.
So this isn't about big bills. It is about a clear message from the grid: over 4 million Australian homes now have rooftop solar, and between 11am and 12pm, wholesale electricity prices are negative roughly 42% of the time. There is simply too much solar sloshing around at midday. The two-way tariff is designed to nudge you into using that power rather than dumping it onto an already overwhelmed network.
Importantly, the two-way tariff also has an upside: solar owners who can export after 4pm, when the grid actually needs power, are typically rewarded with a higher feed-in credit.

Strategy 1: The "Solar Sponge" — Use It Before You Lose It
The simplest way to beat the export charge is to never trigger it in the first place. Run your appliances during peak solar hours (roughly 10am to 3pm) so your panels are powering your home directly rather than pushing excess to the grid. This is actually the same "soaking" strategy at the heart of the new Solar Sharer offer, which from July 2026 gives millions of Australians three hours of free electricity daily.
Dishwasher and washing machine: Set timers for 10am to 2pm. Both are easy to schedule and collectively draw 1 to 3 kWh per cycle.
Pool pump: If you have one, this is one of the biggest "solar soakers" in the average home. Running it at midday rather than overnight can make a meaningful dent in your exports.
Air-Con Pre-Cooling: Run your AC hard around midday to cool the house down while solar is essentially free, then dial it back by 4pm when grid prices spike in the evening.
Hot water systems: This one is underrated. Shifting your hot water heater to run during midday solar hours, especially if you have a heat pump hot water system, can absorb a significant chunk of your solar generation and is one of the highest-value changes you can make.
Strategy 2: Wholesale Arbitrage — The Amber Electric Approach
If you have a battery and want to go further, a wholesale energy plan like Amber Electric opens up a genuinely powerful strategy. Midday electricity prices are now negative a large proportion of the time, which means the grid effectively pays you to consume electricity during those hours.
Amber's AI-powered SmartShift technology looks at your solar generation, your energy usage, and live wholesale market forecasts to automatically charge your battery when prices are low or negative, then export that stored energy back to the grid during evening peaks when prices are high, sometimes reaching $19 per kWh during demand spikes.
You don't need to manually watch prices. The app handles it. The core loop looks like this:
Midday (often negative pricing): Your battery charges from solar or the grid and you get paid to fill it.
Late afternoon and evening peak (6pm to 8pm): Your battery exports to the grid at high prices, or powers your home to avoid buying expensive grid electricity.
This is similar to joining a Virtual Power Plant, where your battery earns passive income by responding to grid demand. The key difference is that a wholesale plan like Amber gives you more direct control. Not sure if your battery is the right size for either approach? Our Battery Calculator can help you work it out.
Strategy 3: Dynamic Export Limits — Let Your Inverter Do the Work
If your solar system was installed in 2024 or later, there's a good chance your inverter supports Dynamic Exports (also called Flexible Exports). This is worth understanding because it directly affects how much you earn on your feed-in tariff.
Traditional solar connections are given a fixed export cap, often 5 kW, regardless of what the grid actually needs at any moment. Dynamic Exports change this: your inverter communicates in real time with the network, which can allow higher exports when the grid has capacity and throttle back only when it doesn't.
The practical benefit? During shoulder periods, typically early morning and late afternoon when the grid wants solar, you can export at full capacity and earn the best available feed-in credits. You're only curtailed when there's genuinely too much power on the network, which is the exact time the export charge would apply anyway.
Check with your installer or inverter manufacturer — brands like Fronius, SolarEdge, Sungrow, and Enphase all support this in recent models — and contact your network distributor to see if the feature has been activated in your area.
The Bottom Line
The "Solar Tax" sounds alarming, but the real story is more nuanced. For most households, the direct financial impact is minimal. The bigger shift is strategic: in 2026, the biggest benefit of solar comes from self-consumption rather than exports. Avoiding the purchase of one kilowatt-hour of grid electricity saves you roughly 30 cents, while exporting that same kilowatt-hour might earn you around 5 cents.
Shift your loads to midday, consider a battery if your usage justifies it (with the May 1st rebate deadline fast approaching, the numbers are looking better than ever and waiting could cost you over $1,000 in lost subsidies), and make sure your inverter settings are optimised. If you're still on the fence about whether a battery makes sense for your home, our honest breakdown of solar batteries in 2026 is a good place to start.
The households treating their solar system as an active energy management tool rather than a set-and-forget appliance are the ones winning in the current market.
