eco-charged mates!
If you’ve noticed more EVs cruising through your suburb—and not paying at the bowser—that’s because Aussies are pairing rooftop solar with electric vehicles like Vegemite on toast: a perfect combo. Here’s why this revolution matters, how it works, and why SA Energy is right behind you.
1. From Grid Guzzlers to Solar Warriors
Australia’s solar story is already legendary. By the end of 2023, rooftop solar capacity had soared to over 34 GW across more than 3.3 million homes Wikipedia+1. That means solar panels are as Australian as footy and the beach.
Nowadays, EVs are charging up from this clean energy boom. In fact, nearly one in ten new cars sold in Australia are electric—around 9.65% in 2024, up from 8.45% in 2023 Cyanergy. Pairing the two means your drive home can be fuelled by your rooftop, not the pump.
2. Home Is Where Most EV Charging Happens
Most EV owners in Oz plug in at home. Surveys show 70–85% of charging is done at home, with only minor usage of public chargers, workplaces, or other locations Australian Energy Regulator (AER). Those with solar panels are more likely to charge their EV during the day—perfectly aligning with sunshine peak hours Australian Energy Regulator (AER).
3. Save Big: Your Rooftop = Free Fuel
Let’s talk dollars: Charging a 60 kWh EV battery from the grid typically costs around AU$15–18. But if you recharge that from your solar array, you're essentially topping up with sunshine—for free Cyanergy.
On the broader scale, smart charging—like plugging in during off-peak times or syncing with solar supply—can save the average EV driver about AU$600 per year, with greater savings in states like South Australia or WA electricvehiclecouncil.com.au.
4. It’s Cleaner, Greener, Smoother
Charging your EV with solar energy cuts out the fossil fuels often hidden behind the grid's electricity mix. It lowers your carbon footprint and helps Australia inch closer to clean energy targets Energy MattersCyanergy. Plus, it gives you some independence from rising power prices—especially if you pair solar with a home battery powersmartsolutions.com.auEnergy Matters.
5. Bidirectional Charging: Your Car as a Power Bank
Picture this: Your EV isn’t just for trips—it’s a backup battery for your home. Thanks to bidirectional charging (also known as V2H/V2G), your EV can feed power back into your house—or even the grid—when needed Energy MattersAustralian Renewable Energy Agencyresearch-management.mq.edu.au.
Australia’s already trailblazed this with a world-first: during a blackout in Victoria, EVs helped power homes back up Australian Renewable Energy Agency. And game-changing policy is on the way: South Australia has approved V2G connections, and projects suggest up to 2.6 million homes could tap into this by 2040 Adelaide Now.
6. EV + Solar = Smart, Stylish, Value-Boosting Homes
Installing a solar-ready EV charger doesn't just make sense—it adds value. Research shows 73% of Australians reckon solar boosts property value, especially in areas like Adelaide, Hobart, and regional locations The Daily Telegraph.
Plus, you’ll stand out in a crowd—“smart, eco-charged suburbs” are becoming the new norm, with clever buyers (and renters) looking for energy efficiency and savings.
7. Policy Momentum is Charging Up Fast
Governments love a good green win. States across Australia offer rebates and incentives:
⦁ Victoria: EV subsidies up to $3,000–$5,000, stamp duty reductions, and lower rego fees
⦁ South Australia: Aiming for 100% EV sales by 2035, plus rebates for home charger installations
Add to that: the feds just lent $100 million to deploy solar panels and EV chargers across major Bunnings and Officeworks stores—giants that could spark broader adoption The Guardian.
