Signs Your Panel May Need an Upgrade
Your panel needs an upgrade when it can't safely carry a charger on top of everything else in the house. A Level 2 charger is one of the biggest loads a home has, and it runs for hours at a time.
These are the signs we look for first:
- Your home has 100 amp service, or less.
- There's no open space in the panel for a double pole breaker.
- You already run an electric range, dryer, water heater and heat pump, and the breakers trip now and then.
- The panel is an older brand like Federal Pacific or Zinsco, which many electricians replace whenever they find one.
- You plan to add a second EV, a hot tub or solar in the next few years.
One of these on its own doesn't mean you need a new panel. It means the panel is worth a closer look before you buy a charger.
The Load Calculation Comes First
A load calculation tells you, on paper, whether your panel can handle a charger. It adds up your home's square footage and every major appliance using the method in the electrical code.
The result is a number in amps. If your service has enough room left over for the charger circuit, you don't need an upgrade at all.
We do this before we quote anything. Replacing a panel you didn't need to replace is an expensive mistake, and so is installing a charger the panel can't carry.
Options That Can Avoid a Panel Upgrade
When a panel is close but not quite there, there's often a cheaper fix than a full upgrade.
- Turn the charger down. Most Level 2 chargers let you set a lower amperage. A 32 amp charger on a 40 amp circuit still covers most daily driving overnight.
- Add a load management device. These watch your home's total draw and slow the charger when other big appliances run, then bring it back up.
- Use a smart splitter. Some homes share one 240 volt circuit between the dryer and the charger, so only one runs at a time.
- Free up space with tandem breakers, where the panel model allows it. This fixes a full panel, not a panel that's short on capacity.
None of these fit every home. The load calculation tells us which ones are on the table for yours.

(704) 555-0142Panel Upgrade or Service Upgrade?
A panel upgrade swaps the breaker box inside your home. A service upgrade raises how much power comes into the house, usually from 100 amps to 200 amps.
A full panel with enough capacity may only need a bigger panel. A 100 amp home that's short on capacity needs the service raised, which means a new meter base and new service wires as well.
Service upgrades involve the power company. In most of Charlotte that's Duke Energy, which disconnects and reconnects power at the meter. Concord runs its own electric system, and parts of Union County are on Union Power.
What a Panel Upgrade Costs
Qmerit's installation cost guide says a service upgrade to 200 amps can add $1,500 to $3,000 to an EV charger job.
Where your price lands depends on the condition of your meter base and the service wires, and how far the panel is from the meter.
If Duke Energy is your power company, its Charger Prep Credit can help pay for the panel upgrade along with the wiring and breaker. The amount and rules change, so we check what applies to your home when we quote.
The federal home charger tax credit ended for installs after June 30, 2026, so don't plan around it.
What to Expect on Upgrade Day
Most panel swaps take a full day, and your power is off for part of it. Plan to work somewhere else, and keep the fridge closed while the power's out.
A service upgrade can take longer, because the power company has to disconnect and reconnect the service. We schedule that with them so you know when the power goes off and when it comes back.
We usually install the charger circuit the same day, since the panel is already open.
Permits and Inspection
Panel and service upgrades need an electrical permit and an inspection. In Charlotte and the other Mecklenburg County towns, that goes through Mecklenburg County Code Enforcement.
Homes in Concord, Waxhaw and Indian Trail go through the Cabarrus or Union County permit offices. We pull the permit and meet the inspector either way.
