Your roof joins the journey.
Charge while the sun is shining and some of your driving energy can come straight from your roof, rather than another grid purchase.

One smarter purchase.
You’re changing how you drive. Why not change how you power it, too?
Pair your electric car with solar and the same roof can help power your home and your kilometres. Make the decision together—not two expensive decisions apart.
Your roof. Your driving. Your finance. No guaranteed savings.

Think household cost
The bigger picture
Don’t just buy a car.
Rethink the bills around it.
An EV replaces petrol with electricity. Solar gives you a way to generate some of that electricity yourself. Together, they connect two recurring household costs: getting around and keeping the lights on.
The compelling question isn’t “Can I afford solar as well?” It’s “What happens to my total monthly spend if I consider both together?”
A car payment is only part of the story. Add fuel, home electricity, charging and solar finance—and you can see the decision that actually matters.
One system. Two everyday needs.
Solar can serve household demand as well as home charging. Size it around both, instead of treating your car and home as separate worlds.
Plan beyond the sunny hours.
A suitable home battery can shift some daytime generation into evening use. Capacity, charging times and losses decide how much—not a sales promise.
Conviction, not guesswork
A no-brainer to compare.
A decision to prove.
Solar isn’t automatically the cheapest option. A shaded roof, costly finance or mostly overnight charging can change the answer. Good advice shows you that before you sign.

Before you commit
Make it your numbers.
Not somebody’s headline.
- Your kilometres and household electricity use
- Your roof’s sunlight, angle and shading
- Your installer’s actual package price
- Your lender’s APR, term and balloon
Good questions. Clear answers.
Will solar make my EV charging free?
Not in an all-in household budget. Sunlight has no fuel bill, but panels, installation, finance, upkeep and battery losses still cost money. Grid and public charging may remain part of your mix.
Can I include solar when financing my EV?
Consider both costs in one household budget, but don’t assume one loan covers everything. Ask your lender which products are available and confirm each APR, deposit, term and balloon. ChargeShift compares vehicle and solar finance separately.
How big a solar system will I need?
It depends on your household electricity use, monthly kilometres, usable roof area, sunlight and charging schedule. An installer should check your roof, inverter and electrical capacity before confirming a system design.
What if my car is away during the day?
Direct solar charging may be limited. A home battery can shift some energy, but overnight grid charging may still be needed. Your charging schedule is part of the comparison.
Will the system work during a power outage?
Only if the installation is designed for backup, with enough stored energy and the right circuits connected. Ordinary grid-tied solar may shut down in an outage. Ask your installer to confirm backup capability; this calculator does not promise off-grid operation.
The next car. The next power bill.
One better-informed decision.
Start with the comparison. Commit when the numbers work for you.
