A lot of older homes in Northwest Arkansas were built with 100-amp electrical service, and at the time, that was plenty. The trouble is that a home built in the 1980s was not designed around central air running all summer, an electric water heater, a houseful of electronics, and now maybe an EV charger or a hot tub on top of all that. The panel that was generous in 1985 can be stretched thin today.

Shannon, the owner of Epic Electric, runs into this constantly in the older homes he works in across the area. The panel is not necessarily broken. It is just being asked to do more than it was sized for, and that shows up in ways homeowners do not always connect back to the panel.

How to tell your panel is stretched

A few signs point to a service that cannot comfortably carry the load it is being asked to handle. Breakers that trip when several big appliances run at once. Lights that dim when the AC or the dryer kicks on. A panel that has no open slots left, so there is nowhere to add a circuit. And the simplest tell of all: you want to add something, an EV charger, a generator, a workshop, a hot tub, and there is no room on the panel for it.

None of these means the panel is dangerous on its own. They mean the panel is full. The distinction matters because the fix is not a repair; it is more capacity.

What a panel upgrade actually is

A service upgrade replaces your existing panel and the service equipment feeding it with a higher-capacity panel, most commonly moving from 100-amp to 200-amp service. That roughly doubles the electrical capacity coming into the home and gives you both the headroom to run everything at once and the open breaker slots to add new circuits going forward.

It is a meaningful job. It involves the utility connection, the meter, the panel itself, and the grounding, and it requires a permit and an inspection. It is not a weekend project or a DIY task, and it is not one to hand to whoever is cheapest. It is the backbone of the home’s entire electrical system.

Why does the panel question come up with almost everything

If you have read our other posts on EV chargers, generators, or even adding lighting circuits, you have seen the same theme: it all comes back to the panel. That is not a coincidence. The panel is the gatekeeper for everything else. A Level 2 EV charger drawing 30 to 50 amps, a whole-house generator, and a hot tub- all of it has to be supported by the service coming into the home.

This is exactly why Epic Electric looks at the panel before quoting almost any addition in an older home. Sometimes there is room, and the addition is simple. Sometimes the honest answer is that the panel needs to come first, and the homeowner deserves to know that before the project starts, rather than discovering it halfway through.

Upgrade, or not?

Not every older home needs a service upgrade. Plenty of 100-amp panels are serving their homes perfectly well because the home’s actual load fits within them. The question is not how old the panel is; it is whether the capacity matches how you actually use the home and what you want to add to it.

The only way to answer that is a load assessment by a licensed electrician who opens the panel, looks at what is on it, and calculates what your home is actually drawing against what the service can provide. Epic Electric does that assessment and gives you a straight answer and a price before any work begins.
