For Australian electric vehicle (EV) owners in 2026, the best time to charge your car for maximum savings is during off-peak electricity hours, typically overnight, or by leveraging your rooftop solar generation during daylight hours. This strategic approach can slash your charging costs from over $20 per session to as little as $5, or even free when using your own solar energy.
With EV sales in Australia surging – over 127,000 battery electric vehicles sold by July 2026 alone – understanding smart charging is no longer a niche concern; it’s essential for every EV owner aiming to minimise running costs. The average cost to fully charge a popular EV like a Tesla Model Y (57.5 kWh battery) at a flat rate of 30c/kWh is around $17.25, while a BYD Sealion 7 (82.6 kWh battery) would cost about $24.78. However, by optimising your charging schedule, these figures can drop dramatically.
The Power of Time-of-Use (ToU) Tariffs
Most Australian households now have, or will soon have, smart meters, enabling Time-of-Use (ToU) electricity tariffs. These tariffs charge different rates for electricity based on the time of day, reflecting grid demand. The key to saving is to shift high-consumption activities, like EV charging, away from expensive peak periods.
Here’s a general breakdown of ToU periods and typical rates as of mid-2026, though exact times and prices vary significantly by state, retailer, and distribution network:
| Period | Typical Times (Example NSW) | Typical Rate (c/kWh) | Best for EV Charging? |
|---|---|---|---|
| Off-Peak | 10 PM - 7 AM (daily) | 8 - 30 | Yes (primary) |
| Shoulder | 7 AM - 2 PM, 8 PM - 10 PM (weekdays) | 30 - 45 | Yes (secondary) |
| Peak | 2 PM - 8 PM (summer weekdays), 5 PM - 9 PM (winter weekdays) | 55 - 70 | No (avoid) |
Note: These are indicative ranges. For instance, in NSW, off-peak rates generally sit around 25-30c/kWh, while peak can hit 70c/kWh. ACT offers off-peak usage for as low as 16c/kWh during 11 am – 3 pm daily on some plans.
Charging a 60 kWh EV during off-peak hours could cost under $5, compared to $20+ during peak times. This difference highlights why understanding your specific tariff is crucial. You can often find your exact rates on your electricity bill or your retailer’s Basic Plan Information Document (BPID).
Maximising Savings with Solar PV
If your home has rooftop solar, your EV becomes an even more powerful tool for energy savings. The ideal strategy is to charge your EV during the middle of the day when your solar panels are generating the most electricity and your household consumption is typically lower. This allows you to maximise your self-consumption of free solar power, rather than exporting it to the grid for often dwindling feed-in tariffs (FiTs).
“Charging on solar or off-peak can save as much as 90% compared with petrol, the equivalent of paying under $0.20 per litre of fuel.”
From July 1, 2026, solar feed-in tariffs have generally decreased across NSW (e.g., from 5c/kWh to 3c/kWh), QLD (2.9c/kWh to 2c/kWh), and SA (2.5c/kWh to 0.8c/kWh). This makes using your self-generated solar power even more financially advantageous than selling it back to the grid.
The New Solar Sharer Offer (2026)
A significant development from July 1, 2026, is the introduction of the ‘Solar Sharer Offer’ by the Australian Energy Regulator (AER) and Victorian Default Offer (VDO). This initiative mandates that all retailers with over 1,000 customers offer a tariff with three hours of free mid-day electricity (up to 24kWh).
- NSW and South East QLD: 11 am - 2 pm daily
- South Australia: 12 pm - 3 pm daily
This offer is available to all residential customers, not just those with solar, providing a prime window for cost-free EV charging during the day. This timing often aligns perfectly with peak solar generation, offering a dual benefit for solar owners.
Smart Charging Solutions and Home Energy Management
To effectively leverage ToU tariffs and solar, smart charging technology is indispensable. Modern EV chargers and Home Energy Management Systems (HEMS) can automate your charging schedule.
-
Smart EV Chargers: Devices like the EcoFlow PowerPulse 2 EV Charger or Ocular IQ Home Solar Universal allow you to schedule charging sessions to coincide with off-peak rates or periods of high solar generation. They can connect to your home’s smart meter and solar system to optimise when and how your EV charges, minimising grid reliance and cost.
-
Home Energy Management Systems (HEMS): These systems integrate your solar panels, home battery (if you have one), and EV charger to create a cohesive energy strategy. A HEMS can predict household demand, solar output, and electricity tariffs to dynamically manage energy flows, ensuring your EV charges from the cheapest source available.

-
In-Car Scheduling: Many popular EVs, such as the Tesla Model Y and Model 3, BYD Atto 3, Hyundai Ioniq, and Kia EV6, include built-in scheduling features that allow you to set preferred charging times directly from the vehicle’s infotainment system or a companion app. This is a basic but effective way to ensure you’re charging during off-peak hours.
The Role of Home Batteries and VPPs
Integrating a home battery with your solar and EV setup offers another layer of optimisation. Instead of solely relying on immediate solar generation, a battery can store excess daytime solar for later use, including charging your EV during the evening shoulder or even some peak periods if the stored energy is cheaper than the grid alternative.
Furthermore, Virtual Power Plants (VPPs) are gaining traction in Australia. If you have a compatible home battery, joining a VPP program can earn you credits or payments by allowing your battery to discharge to the grid during periods of high demand. While direct EV-to-grid (V2G) participation is still in trials, Vehicle-to-Home (V2H) technology is emerging in 2026, enabling your EV to act as a large home battery, powering your house directly during peak times or outages. This adds significant value, turning your EV into a flexible energy asset. To learn more, read: Join a VPP in 2026: Earn Up To $1,500 Annually & Boost Grid Stability.
State-by-State Considerations
While the principles of off-peak and solar charging apply nationally, specific tariffs and incentives can vary:
- NSW, QLD, SA: The AER’s DMO for 2026-27 saw price decreases for residential flat-rate customers in NSW and SE QLD, but a modest increase in SA. However, ToU customers generally saw savings across all three regions.
- Victoria: The Victorian Default Offer (VDO) also saw average domestic rates fall by 5% from August 1, 2026. Victoria has also been a leader in smart meter rollout, making ToU tariffs more common.
- Western Australia & Northern Territory: These states often have higher electricity costs due to climate and infrastructure, making smart charging even more critical for savings.
- ACT: ActewAGL’s standard ToU plans for July 2026 show peak rates up to 49.72c/kWh, shoulder at 33.56c/kWh, and off-peak at 29.92c/kWh, with a specific daytime off-peak of 17.6c/kWh (11 am – 3 pm).
Always check with your specific energy retailer and distribution network for the most accurate and up-to-date tariff information for your postcode.
Home EV Charger Installation Costs
Installing a dedicated Level 2 (Mode 3) home EV charger is crucial for efficient and safe charging. As of July 2026, the average cost for an EV charger installation in Australia, including hardware and basic installation, is $2,237.
| State | Average Installation Cost (July 2026, incl. GST) |
|---|---|
| New South Wales | $2,340 |
| Victoria | $2,201 |
| Queensland | $2,242 |
| ACT | $1,919 |
| Tasmania | $2,011 |
| South Australia | $1,851 |
| Western Australia | $2,586 |
| National Average | $2,237 |

While a standard power outlet (Level 1) can trickle charge your EV (around 10 km range per hour), a dedicated 7.2kW AC home charger adds approximately 30-40 km of range per hour, making it practical for overnight charging.
Bottom Line
To maximise savings when charging your EV in Australia in 2026, prioritise off-peak overnight charging and daytime charging using your home solar system. The introduction of the Solar Sharer Offer from July 1, 2026, provides a significant opportunity for free mid-day charging, even for non-solar owners. Invest in a smart EV charger and consider a Home Energy Management System to automate these processes and truly unlock the lowest charging costs, often bringing a full charge down to under $5. By actively managing when you charge, you can significantly reduce your EV running costs and make the most of Australia’s evolving energy landscape.
