Australia's Solar Share Offer: What Every Homeowner Needs to Know Before July 1

On July 1, the rules around solar in Australia are changing — and most homeowners have no idea it's happening. In Episode 1 of the Off The Grid Podcast, SEG co-founders Jason and Cam sit down to break down exactly what the Solar Share Offer is, what it actually means for your quarterly bill, and the moves that separate the homeowners who win from the ones who end up paying more.

Australia's Electricity Prices Have Nearly Doubled in Four Years

Before diving into what's changing, here's where we actually are. Over the past four years, Australian electricity prices have climbed relentlessly:

The average quarterly bill that sat around $400 in 2021 now sits around $800. It has effectively doubled in four years, and there is no credible sign that trend reverses. The money coming out of household budgets for electricity was going somewhere else five years ago — the mortgage offset, the kids' sport, a weekend away. Now it goes to the network.

What the Solar Share Offer Actually Is

From July 1, every Australian electricity retailer is required to offer the Solar Share Offer: three hours of free electricity between 11am and 3pm, every day.

It's available to anyone with a compatible smart meter — not just solar owners. Renters, apartment dwellers, anyone with the right meter can access those free hours. And on the surface, it sounds like a genuine win from the government.

There are two catches, and the second one is the one that matters.

Catch 1: If you don't already have a smart meter, you pay to have one installed. Nothing is actually free in the energy market — the setup cost sits with the consumer.

Catch 2: Retailers are permitted to increase their standard tariffs on the remaining 21 hours of the day by 1 to 4%.

The Catch Buried in the Fine Print

This is where the Solar Share Offer unravels for most households.

If you're a typical working Australian — out of the house from 7am to 5pm — you're not home during the 11am–3pm window. The free hours don't help you. But the rate increase on the other 21 hours hits you 365 days a year.

As Jason puts it in the episode: "You're offsetting the cost and pushing it out further. It's actually going to make the bill more expensive than it is now."

Retailers won't voluntarily set themselves at 1%. They'll push to 4%. That's not cynicism — that's commercial reality.

The one exception is retirees and people home all day who can genuinely shift their high-draw appliances — dishwasher, washing machine, pool pump — into that window. For them, there's real money to be captured. But for the majority of working households, the maths doesn't go their way.

The reason the government chose 11am–3pm is also worth noting: that's peak solar production time. There's now excess power in the network during those hours, and the feed-in tariff that retailers were paying solar owners has become almost worthless — down from 44 cents per kilowatt hour a decade ago to roughly 3 cents today. The Solar Share Offer lets the government claim a consumer win while the retailers recoup the cost on the other side.

How Solar + Battery Changes the Equation

For homeowners with solar and a battery system, July 1 looks completely different.

The 11am–3pm window is peak solar production. Without a battery, excess solar exports to the grid at ~3 cents per kilowatt hour — essentially worthless. With a battery, that excess charges your system for free. You then draw from stored power at night instead of paying the retailer 33–35 cents per kilowatt hour.

The solar share offer on top means guaranteed full charge, including on overcast days. Cam notes they're seeing batteries deplete after two or three cloudy days — the free forced charge window solves that. Your battery starts every night at full capacity, regardless of what the weather did.

"Instead of getting paid 3 cents, you're storing that and saving 35 cents. Why you'd ever not do that — I don't know." — Jason, Off The Grid Podcast

Under the Solar Share Offer, EV owners with a home battery also get a significant additional benefit: guaranteed full battery and vehicle charge every day during the free window, even on back-to-back overcast days. The solar share offer was partly designed for EV uptake — but the households who've already invested in solar and storage extract the most value from it.

Virtual Power Plants: How to Eliminate the Supply Charge

Even with a fully optimised solar and battery setup, one cost remains: the daily supply charge.

At $1.26 to $1.44 per day depending on your network zone, that's $460 to $525 per year just for having the grid connected to your home — even if you draw zero electricity from it. It's a line item that doesn't disappear with solar.

The answer is a Virtual Power Plant (VPP).

Programs like Amber and Glowbird aggregate home batteries and sell stored power back to the grid during peak demand events. Participating households earn around 15 cents per kilowatt hour for power exported during those windows. Retailers like Glowbird award "Zero to Hero" status to consistent participants, which offsets the daily supply charge — effectively bringing your power bill to zero or very close to it.

One of our customers has solar, a battery, an EV, and a gas connection. By force-charging at low-cost overnight rates and selling back to the grid during peak periods, he offsets both his electricity supply charge and his gas supply charge simultaneously.

Before: $450 per quarter — with rooftop solar already installed.
After: $12 per quarter — after adding a battery, upgrading panels, and joining a VPP.

That's the full stack. Solar handles daytime grid usage. Battery handles night usage. VPP offsets the supply charge. The solar share offer force-charges on overcast days. Each layer compounds the last.

The Battery Rebate Has Already Dropped — And It's Dropping Again

If you've been watching the rebate and planning to get to it eventually, here's the timeline you need to understand.

When the Queensland battery rebate launched, a 50kWh system attracted a government contribution of around $14,000–$15,000. That same system today, after the rebate reduction in May, costs approximately $65,000 at current incentive levels. The government contribution has been substantially wound back.

The pattern since launch: the battery rebate reduces every six months. The next reduction is December. The solar PV rebate (through STCs) reduces every year. Early adopters who installed before the May change locked in tens of thousands more in government contribution than someone installing today.

It's worth noting that a significant portion of the original budget was consumed in the first six months after launch — demand outpaced projections, and the government adjusted the goalposts mid-cycle. That's not a one-time event. It's the pattern.

There's also a separate risk for households still on the legacy 44-cent feed-in tariff from the early adoption period: that rate locks expire in 2028, but can be lost earlier if any alteration is made to the meter or system — including an accidental connection application. Any change whatsoever voids it permanently with no path to reinstatement.

Is It Too Late to Go Solar?

It's never too late — but the economics shift against you every quarter you wait.

The common hesitation points — partial shade, smaller roof, waiting for technology to improve — almost always cost more in delay than they save. If a shaded roof limits production by 50%, that's still 50% off your current bill every quarter for the next 20 years. If you can only fit 28 panels instead of 30, 28 still beats zero.

Well-designed systems typically pay back within four to five years. Over a 15–20 year system life, the return is substantial — and that's before accounting for the fact that grid electricity prices are still rising. Every quarter on full retail rates is money you've paid and can't recover.

As Jason puts it: a dollar today is worth more than a dollar tomorrow. The solar and battery that saves you $800 a quarter from the day it's installed is worth more than the same system installed two years from now — and it's cheaper today, with a bigger rebate, than it will be in December.

We're not going to tell you your bill goes to zero and stays there. That's not honest. The supply charge exists. Overcast stretches happen. But the gap between what you're paying now and what a properly designed system can bring it down to is significant — and it only widens as prices keep rising.
