EV running costs collapse when you charge on rooftop solar instead of petrol — but night-time grid charging on peak tariffs can surprise new drivers. MrSolar’s EV charging cost calculator compares indicative energy costs for Australian households so you can decide how much solar, tariff reform or battery storage belongs in the plan. Pair results with CEC-accredited solar and charger quotes; keep STCs and any ~$372/kWh usable battery discount as separate capital items.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.
Free for homeowners. Participating installers pay MrSolar a lead fee when matched — that does not buy a higher ranking in our guides or reviews. See how we match quotes and is MrSolar legit?

Estimate kWh per kilometre, weekly distance, and the mix of solar versus grid energy. Outputs help you see annual energy cost bands — not including vehicle finance. Because ev charging cost calculator decisions are site-specific, use monitoring or bill interval data where you have it, then ask each CEC-accredited installer to reconcile their design to those facts. If two quotes disagree on “What the calculator compares”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance.
If the car is home in sunshine, surplus PV often beats both petrol and peak grid rates. Smart chargers make that practical without manual babysitting. Keep Epic Unicorn Pty Ltd / MrSolar matching separate from installer contracts: accreditation and incentive claims must appear on the installer’s paperwork for /solar-calculators/ev-charging-cost-calculator. Homeowners comparing EV Charging Cost Calculator Australia — Grid vs Solar Scenarios should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved.
Convenience charging at 7pm can erase EV savings. Controlled-load or EV-specific tariffs may help when solar cannot cover the session. Keep Epic Unicorn Pty Ltd / MrSolar matching separate from installer contracts: accreditation and incentive claims must appear on the installer’s paperwork for /solar-calculators/ev-charging-cost-calculator. Homeowners comparing EV Charging Cost Calculator Australia — Grid vs Solar Scenarios should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved.
Store midday solar for evening plug-ins. Size usable kWh to commute energy. Eligible batteries may receive ~$372/kWh usable federal support. Homeowners comparing EV Charging Cost Calculator Australia — Grid vs Solar Scenarios should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Battery as a bridge”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
Occasional road-trip DC is fine; making it your default usually costs more than home solar charging. Use the calculator to keep home energy as the baseline. If two quotes disagree on “Public DC fast charging versus home”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Public DC fast charging versus home” point for EV charging cost calculator Australia, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/ev-charging-cost-calculator.
If weekly EV kWh exceeds what your current array can spare, discuss upsizing panels or shifting other loads when you request MrSolar quotes. Keep Epic Unicorn Pty Ltd / MrSolar matching separate from installer contracts: accreditation and incentive claims must appear on the installer’s paperwork for /solar-calculators/ev-charging-cost-calculator. Homeowners comparing EV Charging Cost Calculator Australia — Grid vs Solar Scenarios should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved.
Tariffs, FiTs and commute patterns change. Rerun the calculator when you switch retailers or add a second vehicle. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Assumptions to revisit yearly”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “Assumptions to revisit yearly” using your app’s import/export charts — that feedback loop is how EV charging cost calculator Australia stays aligned with real tariffs and DNSP behaviour.
