Most Australian homeowners install solar panels to simplify their relationship with the electricity market. Lower bills, less dependence on the grid, less reason to pay close attention to what retailers are doing. The panels go up, the monitoring app gets checked occasionally, and the assumption settles in that the hard work is done.
That assumption is costing solar households money.
Not because solar does not work. It does. But because installing solar does not opt you out of the electricity retail market. It makes your participation in that market more complex, more consequential, and in some cases more exposed to the practices that Australian regulators have spent the past two years formally investigating.
The Australian Energy Regulator published draft Retail Guidelines requiring energy retailers to communicate with customers in a way that is “honest and fair.” That phrase is a regulatory response to documented evidence that the current baseline is neither.
What the regulator has actually found
In 2024, consumer advocacy group Choice lodged a formal super complaint with the Australian Competition and Consumer Commission (ACCC), alleging widespread use of misleading and confusing pricing tactics by energy retailers. The ACCC launched an investigation. What followed was a finding that certain practices were widespread across the retail energy market.
One of those practices involved presenting customers with better-offer prompts that referred to plans they were not eligible for or that did not exist in the advertised form. Another, documented by Victoria’s Essential Services Commission, was the same-name, different-price problem: around 360,000 Victorian customers were found to be on older, more expensive versions of electricity plans that had cheaper alternatives available under identical names. The plans looked the same. The rates were not.
The AER’s response has been to draft guidelines that replace prescriptive formatting rules with a broader principle of honest and fair communication. Consumer advocates have broadly welcomed the direction while arguing for something more structural: default settings that protect customers who lack the time, digital skills, or confidence to actively navigate a complex market.
As Energy Consumers Australia CEO Brendan French put it last year, consumers should not be penalised simply because they cannot constantly be on the lookout for cheaper prices. Those with the lowest means, he noted, are frequently paying the highest prices for an essential service.
For solar households, the issue sits in a slightly different place. The problem is that the tools available for engagement were not built for their situation.
Why solar households face a more complicated decision
A standard electricity plan comparison involves a small number of variables: the daily supply charge, the usage rate, and the contract terms. A solar household comparison involves all of those plus the feed-in tariff rate, the tariff structure, the alignment between time-of-use windows and actual solar generation hours, battery compatibility where relevant, and VPP participation terms if the household is considering joining one.
Standard comparison sites are not designed to surface all of this simultaneously. They present plans in a format built for non-solar households and leave the solar-specific variables to be discovered separately, if at all.
The feed-in tariff landscape alone illustrates how much complexity solar households are navigating without adequate tools.
In NSW, the Independent Pricing and Regulatory Tribunal sets annual benchmarks for what retailers should pay for exported solar. For 2026-27, the flat daytime rate benchmark has dropped to between 3.4 and 6.5 cents per kilowatt-hour. But IPART sets benchmarks, not rules. Retailers are under no legal obligation to pay time-of-use rates that reward evening solar exports more generously.
As of mid-2026, only four retailers in NSW offer feed-in tariffs that vary by time of day. A solar household with east-west facing panels generating in the late afternoon could be earning 17 to 18 cents per kilowatt-hour for those exports with one of those retailers, or 3 to 6 cents with every other retailer in the state. That difference does not appear on a standard comparison tool. It requires knowing to look for it.
A useful plan comparison for a solar household should account for the daily supply charge, usage rate, tariff type, feed-in tariff rate and structure, controlled load rates, payment conditions, billing frequency, contract terms, and whether the plan is actually available at the relevant address. Most households never see a comparison at that level of detail.
The tariff structure problem nobody explains at installation
Most Australian solar households were put on a flat-rate tariff when their system was installed and have never revisited it. At the time, this was reasonable. Feed-in tariffs were higher, the primary value proposition was export income, and the complexity of time-of-use pricing was not obviously worth engaging with.
The calculation has changed. The average residential electricity customer in Australia is now paying between 30 and 35 cents per kilowatt-hour for grid electricity. Feed-in tariffs for most households sit between 3 and 8 cents per kilowatt-hour. The gap between the cost of importing electricity and the return on exporting it has widened to a point where self-consumption is now far more valuable than export. Every kilowatt-hour a solar household uses directly from its own panels at midday is worth 30 to 35 cents. Every kilowatt-hour exported earns a fraction of that.
This changes what the right tariff structure looks like. Time-of-use tariffs, where peak rates apply in the evening, and off-peak rates apply overnight, create the pricing environment where a battery performs best. A household on a flat rate with a battery installed is leaving a significant portion of that battery’s financial value uncaptured. Because the import rate is the same regardless of time of day, there is no price differential to arbitrage. The battery is doing less work than it could.
The complication is that switching to time-of-use is not automatically the right move for every solar household. It depends on when the household actually uses power, whether a battery is installed, how large the system is, and what the specific peak and off-peak rates are for the plans available in that area.
The loyalty trap
The single most common mistake solar households make with energy plans is staying on the wrong one for too long. The installer recommended a retailer. The retailer offered a competitive feed-in tariff at installation. The household stayed. Rates changed, feed-in tariffs dropped, better options emerged, and because the bill was lower than before solar, the household assumed everything was still optimised.
It rarely is. EnergyAustralia’s feed-in tariff rate drops to 3 cents per kilowatt-hour from 1 July 2026. Affected customers are being notified from mid-June. A customer who receives that notification and does nothing is accepting a rate that may be materially below what is available elsewhere. A customer who treats it as a prompt to check the market may find a meaningful difference.
The market for solar-specific electricity plans has become more varied and more competitive over the past two years, precisely because the economics of solar have changed and retailers are responding to that. The problem is that the tools for navigating that market have not kept pace, and the practices the AER is now addressing have made the market harder to read, not easier.
What a fair system would look like for solar households
The AER’s draft guidelines are aimed at honest and fair communication. Consumer advocates are right to note that communication reform is not the same as structural reform. A system that is honest and fair in its communications but still requires significant active effort to navigate will still disadvantage the people who cannot invest that effort.
For solar households specifically, a genuinely fair system would do a few things that the current system does not. It would present plan comparisons that account for the generation profile, not just the consumption. It would require retailers to proactively notify customers when their feed-in tariff has dropped below the market benchmark for their state. It would make time-of-use window timing visible in the comparison process, not buried in product disclosure statements. And it would flag when a customer’s current tariff structure is likely misaligned with their setup.
None of this exists yet. The draft guidelines are a step in the right direction on transparency. But transparency requires a reader who has the information and tools to act on it. Solar households have more variables to act on than most.
Three things worth doing before your next bill
The argument of this piece is structural, but the action is individual. Three things worth doing in the next week.
- Find out what feed-in tariff you are actually receiving. Look for it on your bill, not your monitoring app. The monitoring app shows generation. The bill shows what you are being paid for it. If you are receiving less than five cents per kilowatt-hour and have not compared your plan in the past twelve months, the market has moved since you last looked.
- Check what tariff structure you are on. If you have a battery and are on a flat rate, understand what time-of-use pricing would mean for your specific usage pattern before deciding whether to switch. The answer is not always to switch, but it should be a decision made with current information.
- When a better offer alert appears on your next bill, do not ignore it and do not accept it automatically. Evaluate it against your actual situation as a solar household. A better offer for a non-solar customer in your area is not necessarily a better offer for you.
If you have not compared your energy plan since installing solar, now is a practical time to do it. The market has changed significantly in the past two years and the plan that was right at installation may not be the right plan now.
