The quote says "panel upgrade required" but gives no load calculation.
Ask what number failed and what assumptions were used for the charger amperage.
Buyer rule: a panel upgrade is a quote conclusion, not a starting assumption. Ask for three paths in writing: a right-sized circuit, load management, and a full panel upgrade. Then compare the actual scope.
Load calculation
The panel has to prove it can carry the charger
Level 2 home chargers use 240-volt power. The U.S. Department of Energy says some homes may have insufficient electric capacity for Level 2 equipment, and that a qualified electrician can add circuits when more capacity is needed.
That does not mean every older Atlanta house needs a panel upgrade. It means the electrician has to look at the service size, open breaker spaces, existing loads, proposed charger amperage, and code requirements before pricing the job.
Get the load calculation. Without it, "you need a new panel" is just a sales sentence with a large number attached.
Quote paths
There are three real ways a quote can go
PathWhen it fitsWhat to ask
Right-sized circuitThe panel has capacity, but the charger does not need maximum amperage."What amperage fits my driving and my panel?"
Load managementThe panel is tight, but charging can be limited or paused when the house is using more power."Can load management avoid the upgrade?"
Panel upgradeThe service or panel cannot safely support the charger circuit and other home loads."What failed in the load calculation?"
Maximum amperage is not the prize
Many drivers do not need the fastest charger setting their equipment can support. If Georgia Power's overnight window is 11 p.m. to 7 a.m., the better question is whether your setup can replace a normal day of driving during that window.
A smaller circuit that works every night may beat a bigger circuit that forces a $3,000 panel upgrade.
Red flags
When a panel-upgrade quote deserves a second look
The installer prices only the fastest charging option.
Ask for a second quote at a lower amperage. The car does not care about bragging rights. It cares whether it is charged by morning.
The permit is missing from the quote.
Georgia Power's EV resources page says a permit may be required for some higher-voltage home charger installations. Missing permit language is not a discount. Use the permit guide before approving the job.
Load management is never discussed.
It will not fit every home. Still, a serious quote should say whether it was considered.
Before the visit
Send these details before the installer arrives
Good photos can save a wasted appointment: main panel, main breaker rating, open breaker spaces, the parking spot, the route between panel and charger, and any big electric loads such as HVAC, water heater, range, hot tub, pool equipment, or existing subpanels.
ENERGY STAR tells homeowners to find the main panel, check the main breaker amperage, and look for empty spaces before planning new electric loads. That is not the whole load calculation, but it gives the installer a faster first read.
Cost impact
What does this do to the Atlanta budget?
The current Atlanta cost guide uses $1,000 to $3,000 as the working range for a panel upgrade when required. Load management is tracked as a lower-cost workaround when it fits the home.
