Solar Sharer: 3 Hours Of Free Power Explained

Three hours of free electricity every day sounds like a pretty good deal on the face of it.

That’s the promise behind the Solar Sharer Offer, a new scheme launching in NSW, South-East Queensland and South Australia from July 2026.

In a recent SolarQuotes video, SolarQuotes founder Finn Peacock breaks down what’s actually going on — and why “free power” isn’t quite as simple as it sounds.

What Is The Solar Sharer Offer?

From 1 July 2026, electricity retailers in NSW, SEQ and South Australia will be required to offer at least one residential plan that includes a three-hour block of free electricity in the middle of the day, with a 24 kWh daily cap.

But households aren’t forced onto these plans. Retailers must offer them — customers choose whether to opt in.

It’s a response to a grid that now produces too much solar in the middle of the day and not enough flexible demand to match it.

With more than 4 million rooftop solar systems across Australia, midday generation regularly pushes wholesale prices to zero or negative. In some cases, utility-scale solar is curtailed simply because there’s too much electricity and not enough demand.

The Solar Sharer idea is to shift that demand into the middle of the day instead of letting the energy go to waste.

There are also plans to expand the scheme nationally after the initial roll-out.

How The ‘Free’ Electricity Works

To access it, you’ll need a smart meter and an eligible plan.

Retailers still recover revenue elsewhere in the tariff, typically through higher peak rates, higher shoulder rates, or higher daily supply charges.

Some retailers already run versions of this voluntarily. From 2026, every retailer must offer at least one compliant plan — but the underlying cost balance doesn’t change.

Who Actually Benefits?

The biggest winners are households that can shift or store energy — and the difference can be significant.

Take solar batteries first. Charging during a zero-cost midday window and discharging during evening peak pricing is where the value really shows up.

EV charging is another big one, but timing is everything. A standard trickle charger might only add around 6 kWh in three hours — roughly 10% of a typical EV battery. A 3-phase home charger can push closer to 30 kWh in the same period — around 50% for many EVs. Same policy, completely different outcome depending on your hardware.

Hot water is also a major lever. Shifting a resistive electric or hot water heat pump system into the middle of the day can eliminate one of the largest daily loads in a typical household.

Then there’s everything else — dishwashers, washing machines, dryers, pool pumps, air conditioning. Individually small, but together they start to matter.

The rough rule of thumb is this: you need to shift at least around 6 kWh of daily consumption into the free period to come out ahead once higher peak and supply charges are factored in. For some households, that’s easy. For others, it’s a stretch.

Finn reckons you need to move at least 6 kWh into the free window to make it work.

The Case For Solar Sharer

At a system level, the logic is hard to argue with.

Australia is already hitting periods where rooftop solar overwhelms daytime demand. That leads to curtailment, negative pricing, and wasted renewable generation.

Shifting consumption into the middle of the day helps absorb excess solar instead of switching it off.

It also takes pressure off the evening peak — still the most expensive and grid-stressed period.

And for battery owners, it creates a predictable midday charging window they can plan around.

The Case Against Solar Sharer

The biggest concern is that it could slow solar uptake.

If households hear “three hours of free electricity every day”, some will inevitably ask why they’d spend thousands on solar panels when they can simply use free grid power at lunchtime instead.

But that overlooks one of solar’s biggest advantages: autonomy. A household with a decent solar system isn’t tied to a Solar Sharer tariff and can choose from a wider range of electricity plans, including ones with lower peak rates and supply charges.

There are also concerns about the way the scheme is being implemented. Retailers are being required to offer a product with free electricity during part of the day, but the costs don’t disappear. Existing plans typically recover them through higher rates outside the free window.

The bigger issue is what happens if the message people take away is simply: “Why bother with solar?”

Australia needs to dramatically expand renewable generation over the coming decade, with around 65 GW of large-scale capacity needed by 2030 to stay on track with current targets. Rooftop solar remains a critical part of that transition.

What This Means For Your Bill

The Solar Sharer Offer isn’t a gimmick, and it isn’t a universal discount either.

It’s a structural response to a grid that now produces too much solar in the middle of the day and not enough flexible demand to match it.

If you can shift or store energy, it could work strongly in your favour. If you can’t, it becomes another tariff design that needs careful comparison rather than headline optimism.

Either way, the key point remains: “free” electricity only works if you can actually move your usage into the right three-hour window — and have the setup in place to make it count.
