Category: EV Chargers · By Alex, Ultralec
Every new EV owner on the Sunshine Coast runs through roughly the same set of questions in their first month: Should I install a home charger? How fast will it charge my car? Is it actually cheaper than public charging? What about charging off my solar? How much will installation cost? And is my existing switchboard going to handle it? These are all sensible questions — and the answers are more specific than most generic internet explainers admit.
We run the actual numbers for a Sunshine Coast EV driver doing a typical 15,000 km per year — comparing public charger costs, home off-peak charging, and home solar-charging. Covers real installation costs for Level 2 chargers, when a switchboard upgrade is needed, and when it's cheaper to just keep using public chargers.
If you own an EV (or you're planning to buy one) and you live anywhere on the Sunshine Coast or Noosa Hinterland, installing a home Level 2 EV charger is almost always the better option than relying on public charging. It's faster, cheaper, more convenient, and opens up options like solar charging that public stations can't offer. Here's the full breakdown.
There are three main types of EV charging, and understanding the differences is the first step.
A normal 10A or 15A power point. Adds about 10-15km of range per hour of charging. A full charge of a typical 60kWh battery EV takes 20-30 hours. Fine for plug-in hybrids with small batteries, completely inadequate for daily EV use.
A dedicated home wallbox. Adds 40km range per hour (7kW) or up to 120km per hour (22kW three-phase). Full charge of a 60kWh battery takes 8 hours at 7kW — easily done overnight. This is what most EV owners install at home.
Public fast chargers at Tesla Superchargers, Chargefox sites, BP Pulse stations etc. Adds 150-800+ km of range per hour. Great for road trips, but you can't install one at home — they require commercial-grade three-phase power and substantial infrastructure.
Home charging in Queensland costs approximately $0.05-0.08 per km (using off-peak rates or solar). Public fast charging costs $0.20-0.35 per km. Over a year of typical driving (15,000km), home charging saves you $2,250-$4,050. Over the life of the vehicle, the home charger pays for itself several times over.
You plug in when you get home, wake up full. No detours, no queues, no waiting around. The car is always ready to go with 350-500km of range at the start of the day. For Sunshine Coast and Noosa Hinterland drivers, this means essentially never thinking about charging for local driving.
If you have solar panels, your home EV charger can be configured to charge the car preferentially from surplus solar during the day (or from battery storage). This effectively gives you free driving — the marginal cost of charging from solar you're otherwise exporting at 6¢/kWh is near-zero. Public chargers can't do this.
Level 2 AC charging is gentler on your EV battery than repeated DC fast charging. Manufacturers increasingly note that daily DC fast charging can accelerate battery degradation over time. Home Level 2 charging is the recommended charging method for long-term battery health.
Sunshine Coast public charging is improving but still has gaps — chargers out of service, occupied when you arrive, access issues. Home charging eliminates these headaches for 95% of your driving.
A proper home EV charger installation by a licensed electrical contractor includes several key steps.
Your existing switchboard must have capacity for the new circuit. Many older Pomona, Cooroy and Noosa homes need a switchboard upgrade before (or at the same time as) the EV charger install. We assess this up front so there are no surprises.
A dedicated cable runs from the switchboard to the charger location, sized for the charger rating — typically 32A for a 7kW single-phase charger. Cable route matters for cost and aesthetics; we walk the job with the customer to agree the best route.
Charger mounted on a suitable wall — garage wall, carport, or external wall. Weatherproofing matters for external installations (IP rating of the charger).
Charger configured correctly for your usage pattern — time-of-use scheduling, solar integration settings, authentication if required.
Certificate of electrical safety issued, full AS/NZS 3000 compliance. EV charger installs are notifiable work under Queensland electrical legislation.

Home charging handles 95% of your driving. Public charging is essential for:
The Sunshine Coast public charging network includes Tesla Superchargers at several locations, Chargefox and Evie sites, and a growing network of councils installing destination chargers. For road trips it's genuinely usable now, especially up and down the coast.
An EV driving 15,000km per year uses around 2,500-3,000 kWh. At typical off-peak rates that's $400-600 per year in electricity — about $10 per week. In exchange you're not buying $2,500-3,500 in petrol per year. Net saving: huge.
Yes, especially with smart chargers like Zappi or Tesla Wall Connector v3 that can be configured to charge only from surplus solar. If you have 6.6kW+ of solar and charge during the day, much of your driving can effectively be free.
Only if you want faster than 7kW charging (most home users don't). Three-phase chargers can deliver up to 22kW, which charges a 60kWh EV from 20-80% in under 2 hours. Useful for fleet vehicles or people with multiple EVs.
Typical installed cost: $1,800-$3,500 for a single-phase 7kW charger, depending on charger brand, cable run length, switchboard work required, and mounting complexity. Three-phase installs are more.
