Solar Sharer Offer: What It Really Means If You Already Have Solar and Batteries

The headlines sound alarming: "Free electricity for everyone (no solar needed)."

If you've already invested in solar panels and a home battery, you might be wondering whether you've been beaten to the punch. Why pay for a system when the government is handing out free power?

Here's the reality: the Solar Sharer Offer changes the economics in your favour. This article explains exactly what it is, what triggered it, and why solar and battery owners in NSW, South East Queensland, and South Australia are among the biggest winners.

What Is the Solar Sharer Offer?

The Solar Sharer Offer (SSO) is a federal government policy announced in November 2025 by Energy Minister Chris Bowen. From 1 July 2026, energy retailers in NSW, South East Queensland, and South Australia are required to offer households at least three hours of free electricity per day (typically between 11am and 2pm) when solar generation peaks and wholesale electricity prices drop to zero or go negative.

The regulation was formally enacted through the Competition and Consumer (Industry Code: Electricity Retail) Amendment Regulations 2026 and sits under the Default Market Offer (DMO) framework, overseen by the Australian Energy Regulator (AER).

It's opt-in: retailers must offer a Solar Sharer plan, but households choose whether to take it up. You'll need a smart meter to be eligible.

A 24 kWh daily cap applies to the free period (sized around the average needs of a five-person household). Anything above that cap is charged at standard rates.

The plan is to extend the offer to Victoria and Western Australia by 2027.

Why Did This Policy Happen?

Australia now has more than 4 million rooftop solar installations, making it the most solar-dense country on earth. That success has created an unintended consequence: midday electricity prices on the wholesale market regularly fall to zero or even go negative because there's more supply than demand.

This has eroded feed-in tariffs for solar owners over recent years. Retailers aren't paying much for your solar exports at midday because the grid already has more power than it knows what to do with.

The Solar Sharer Offer is designed to address this by pulling more demand into the middle of the day by smoothing the grid, reducing the need for expensive network upgrades, and cutting evening peak prices.

Put simply: the grid has a midday surplus problem, and the government wants households to help soak it up.

The Catch: "Free" Doesn't Always Mean Cheaper

Before switching plans, understand the trade-off. Retailers offering three hours of free electricity need to recover those costs somewhere. In practice, that typically means:

• Higher peak usage rates (5pm–9pm)
• Higher daily supply charges
• Lower or restructured feed-in tariffs

AGL's voluntary "Three for Free" plan, launched in South Australia in July 2025, is an early example of this. Its supply and usage charges outside the free window are higher than standard plans. The Solar Sharer Offer becomes the regulated benchmark from July 2026, but the cost-recovery logic is the same.

If you use most of your power in the evenings and can't shift usage to midday, your bill could actually increase on a Solar Sharer tariff compared to your current flat-rate or TOU plan. Always compare the full plan and not just the free hours.

Why Battery Owners Win the Most

Here's where it gets interesting for Aussie Solar Batteries customers.

A home battery turns the Solar Sharer Offer into a genuine financial advantage. Not just a convenience.

The strategy is simple: charge your battery for free between 11am and 2pm, then discharge it during the expensive evening peak (5pm–9pm) when grid rates are at their highest. You're essentially buying electricity at $0/kWh and avoiding rates that can reach $0.50–$0.60/kWh during peak periods.

A 4–5 person household consuming around 10 kWh during peak hours pays roughly $1,050 per year in peak electricity costs on a standard flat-rate tariff. A correctly sized battery, charged entirely during the free window, eliminates that cost. With the right system, payback accelerates significantly under the new tariff structure.

One installer's analysis found that switching to a Solar Sharer tariff without a battery would likely increase most households' bills. But sizing a battery to cover peak consumption hours is where the majority of savings are made.

Beyond the bill savings, battery owners also have flexibility that non-battery households don't. On days with strong solar generation, your panels may fully charge your battery well before the free window opens, meaning the three free hours function as a backup top-up on cloudy days, not your only source of stored energy.

What About Solar Owners Without Batteries?

If you have solar panels but no battery, the picture is more nuanced.

Your solar generation already means you're self-consuming during daylight hours, so the free window may offer less marginal benefit than it does to a household drawing entirely from the grid. The more important consideration is whether a Solar Sharer tariff's peak and supply charges work in your favour compared to your current plan.

The good news: the AER is regulating the SSO specifically to prevent retailers from inflating rates outside the free window to offset the cost. The regulatory intent is consumer protection. Reading the fine print on any individual plan remains essential.

One genuine concern among solar owners is whether the scheme accelerates the decline in feed-in tariffs. While no specific changes to feed-in tariffs have been announced, the structural pressure on midday exports has been building for years. The Solar Sharer Offer is, at least in part, a response to that pressure, and a well-designed battery helps you sidestep feed-in tariff risk entirely by maximising self-consumption.

Smart Meter: The Non-Negotiable First Step

To access any Solar Sharer plan, your home needs a smart meter. Most new solar installations include one by default, but if yours doesn't, contact your retailer to arrange an upgrade.

Without a smart meter, the three-hour free window cannot be correctly applied to your account. You will remain on whatever tariff you're currently on.

The Bigger Picture: Why Solar and Batteries Still Make Sense

Some media coverage of the Solar Sharer Offer has framed it as a reason not to bother with solar. That's the wrong read.

The free window covers three hours of midday generation. A quality solar and battery system gives you energy independence across the entire day: evenings, cloudy days, and potential grid outages. It protects you from rate increases outside the free window. And it gives you the asset that makes the Solar Sharer Offer most valuable in the first place.

The Solar Sharer Offer is proof that Australia's grid is awash in solar during the day. That's not an argument against solar. It's an argument for storage. The households who invested in batteries are now positioned to capture free midday electricity and avoid peak pricing. Everyone else is catching up.

Key Dates and What to Do Now

• SSO announced: November 2025
• Regulations enacted: Early 2026
• Solar Sharer plans available (NSW, SEQ, SA): 1 July 2026
• National rollout (VIC, WA): 2027 (planned)

If you already have solar and a battery: Review whether a Solar Sharer plan makes sense based on your usage profile, especially your evening consumption. Your retailer can advise or ask us.

If you have solar but no battery: The Solar Sharer Offer is a good prompt to model whether a battery now stacks up financially. With peak tariff rates set to increase on Solar Sharer plans, the payback maths may have shifted in your favour.

If you're yet to install either: The combination of the Solar Sharer Offer, the NSW Home Energy Saver loan scheme, and available federal battery rebates makes this one of the strongest economic cases for solar and storage Australia has seen.
