How the Victorian Midday Power Saver Works With Solar Panels

Yes, it is worth investigating — but don't assume it will automatically save you more money.

The Victorian Government specifically says households with rooftop solar can still benefit, especially where they have an EV or home battery that can be charged during the free period.

Your solar panels already provide electricity during daylight hours. The Midday Power Saver adds another option:

The best arrangement depends on which of those energy flows actually makes sense for your home.

Victoria already has one of Australia's largest rooftop solar markets, with more than 850,000 small-scale solar PV systems installed across the state. Solar Victoria says rooftop solar now contributes around 10% of Victoria's electricity generation.

Now Victoria has introduced another major change:

The government designed the program to encourage more electricity consumption during the middle of the day, when renewable generation is abundant.

For solar households, that creates an unusual situation. Your home may already have electricity available from the roof. At the same time, the grid may offer electricity at $0/kWh during the same period.

This is the first distinction to understand.

So you have two separate things happening:

That means they can operate alongside each other.

Imagine a Melbourne home with a 10kW solar system.

In this situation, the home is already making substantial use of solar. There may be little reason to deliberately replace solar consumption with grid electricity.

The home needs more electricity than the panels are currently producing. If the household is on the Midday Power Saver, eligible grid usage during the free window can potentially help cover that additional demand. This is where the tariff becomes interesting.

There is no single answer for every home. A useful priority framework is:

This is an important point. The objective isn't to stop using your solar. If your solar panels are producing electricity and your home needs electricity, using your own solar can still be sensible.

Instead, think about the difference between:

If your solar is already covering your home's electricity consumption, there may be little reason to deliberately draw from the grid. But if you have excess solar that would otherwise be exported, your energy strategy becomes more complicated.

You need to consider:

Suppose your solar system is generating 8kW, your home is using 3kW, and your battery can accept 3kW. That leaves 2kW which may be exported to the grid, depending on your system and network arrangements.

Now consider the Midday Power Saver. The existence of free grid electricity does not mean your excess solar suddenly becomes worthless. You still need to consider what you receive for exported solar and whether another use — such as battery charging, hot water or EV charging — would provide greater value.

This is where many homeowners will start asking questions.

Consider a battery with 10kWh usable capacity. If your solar is generating enough surplus to fill it during the day, there may be little reason to use grid electricity to charge it. But if the weather is cloudy and your solar generation is insufficient, the free period could potentially provide an opportunity to charge some battery capacity.

However, your battery's:

A modern Melbourne home may have three different electricity sources or storage pathways:

The Midday Power Saver adds a fourth consideration: free grid electricity available between 11am and 2pm. Now your energy strategy can look like this:

This can be much more sophisticated than simply saying: "I have solar, so I don't need the Midday Power Saver."

An EV can make the Midday Power Saver particularly relevant. Why? Because an EV is effectively a large flexible electricity load. If your car is parked at home during the day, you may be able to schedule charging between 11am and 2pm.

The Victorian Government specifically identifies EV charging as one of the uses that can be shifted into the free period. It estimates households with an EV could potentially save an additional $674 compared with charging at peak times, depending on household circumstances and usage assumptions.

Same electricity plan. Completely different opportunity.

Suppose your solar system is producing 5kW. Your house is using 2kW. You have an EV connected to a charger. You could potentially direct the remaining solar generation toward the vehicle.

This increases direct solar use.

Now consider a cloudy day. Solar produces only 1kW. The EV needs 7kWh or more. During the Midday Power Saver period, the grid can potentially supply the additional electricity at no usage charge under the offer.

Absolutely — and this is one of the most practical combinations for a Melbourne home. A heat pump hot water system does not need to heat water at exactly the moment you need a shower. It heats and stores hot water in a tank. That makes hot water a flexible energy load.

Solar Victoria has published examples of Victorian households using timers to operate heat pumps around periods of strong solar generation.

This is an excellent example of why the future of home energy is increasingly about timing, not just equipment.

Melbourne homes can also use the midday period for heating or cooling. If your home is occupied during the day, running efficient air conditioning during the free period may reduce the cost of daytime grid electricity.

For example:

• Pre-cool a home before afternoon heat
• Heat occupied rooms efficiently
• Use efficient reverse-cycle systems
• Combine operation with solar generation
• Use timers where practical

The objective is comfort at lower overall cost — not maximum electricity consumption.

Consider a four-person home in Melbourne with:

The family works partly from home.

Instead of automatically discharging the battery or paying the normal grid rate, the household may be able to use the Midday Power Saver for the additional grid requirement.

You don't necessarily need one. This is an important point. If you have solar but no battery, you can still improve solar self-consumption by moving flexible electricity use into the daytime.

The Midday Power Saver can then provide another option when solar generation is insufficient. A battery may become useful later if you have substantial evening electricity demand, but it should not be treated as an automatic next purchase.

This is where the Midday Power Saver can create confusion. Some homeowners may think: "If electricity is free from 11am to 2pm, why should I install solar?"

Because the free period and solar solve different problems.

• The Midday Power Saver gives you access to a three-hour free grid usage window.
• Solar gives your home the ability to generate electricity itself.
• Solar can generate outside the 11am–2pm period.
• It can also produce electricity when your household needs it outside the free period.
• And with appropriate system design, excess generation can potentially be stored in a battery.

So the question for a new solar customer should be:

Those questions remain relevant even after the Midday Power Saver begins.

Not necessarily. In fact, the program reinforces something that solar installers have been telling homeowners for years: Daytime electricity has value.

The Victorian Government says the program is designed to encourage households to shift electricity use into the middle of the day when renewable generation is abundant. For solar homeowners, that means the focus should increasingly be on self-consumption and flexible energy use.

This does not mean every home needs a battery. It means every home should understand its electricity flows.

The Midday Power Saver does not remove the need to size solar correctly.

A system that is too small may struggle to cover household consumption, EV charging, heat pump hot water, air conditioning, and battery charging. A system that is oversized may have substantial periods of surplus generation.

The right system depends on:

This is why Samsun Energy should not recommend a solar system simply from the number of bedrooms in a house.

Start with your electricity data. Look at a typical day and identify:

Then compare this with your solar generation. You may discover that your biggest opportunity is not a larger solar system. It could be:

• A better appliance schedule
• EV charging during solar hours
• Heat pump scheduling
• Better battery settings
• More solar
• A battery
• A combination of these

Use this checklist before changing your battery settings.

A solar panel installation used to be a relatively simple conversation.

Today, a Melbourne home can look very different:

The Midday Power Saver adds another piece to the puzzle.

At Samsun Energy, the starting point should be your home rather than a standard package.

The Victorian Government identifies solar households with EVs or home batteries as potential beneficiaries of the free period. It also notes that households with pool pumps, heating or other energy-intensive flexible loads may be able to shift consumption into the middle of the day.

The combination can be particularly interesting if you:

The Midday Power Saver may not be the right fit if most of your electricity use is difficult to move. For example:

This is why the Victorian Government recommends comparing the offer before switching. Victorian Energy Compare can be used to compare electricity offers based on your circumstances.

There are several things the headline doesn't explain.

You don't need to rush out and buy a battery. You don't need to replace your solar system. And you don't need to switch electricity plans simply because the word "free" appears in the offer.

Instead:

Victoria has already seen massive rooftop solar adoption. The next stage is not simply putting more panels on roofs. It is about making better use of the electricity those panels generate.

The Midday Power Saver is part of that shift.

The opportunity is to make these systems work together.

That's the direction the modern Melbourne home is heading.

Possibly — and it is worth checking your numbers.

If your solar system already covers most of your daytime electricity use, the benefit may be limited.

But if you have an EV, battery, heat pump, pool pump, air conditioning or other flexible loads, the 11am–2pm free electricity window could become another useful part of your household energy strategy.

The Victorian Government estimates eligible households could save $149–$428 per year, depending on circumstances and the amount of electricity shifted into the free period. For households with an EV, it estimates additional potential savings from shifting EV charging into the free period. These are estimates, not guarantees.
