A smart electrical panel gives you real-time visibility into every circuit in your home, lets you control individual breakers from your phone, and can automatically manage loads — shifting power away from the dryer when your EV is charging, for example. They cost $3,000 – $8,000 installed in NJ. And honestly, most homeowners don't need one. But for a growing group of households — those adding EVs, solar, and heat pumps — they genuinely change what's possible. Here's how to think about it.
I'll be upfront: smart panels are a newer product category that we're enthusiastic about but measured on. Michael Malfettone has a computer science background before his electrical career, and we've followed these devices since the first Span units shipped. The technology is real and useful. The question is whether it's the right tool for your home.
What Is a Smart Electrical Panel?
A smart electrical panel replaces your traditional breaker panel and adds circuit-level intelligence: sensors on every circuit, a touch display on the unit itself, a companion app for your phone, and an API that allows integration with home energy systems like Tesla Powerwall, Enphase, and EV chargers.
With a smart panel, you can:
- See in real time exactly how much power each circuit is drawing — not just the total, but the dryer, the HVAC, the EV charger, and each room separately.
- Set circuit priorities, so that if the grid goes out and you're running on battery, the panel automatically cuts non-essential loads and keeps your refrigerator, lights, and medical equipment running.
- Manage EV charging dynamically — charge at full speed when electricity is cheap (overnight, or during solar production), slow down or pause when the house demand is high.
- Control breakers remotely. If you're traveling and want to make sure the hot tub isn't drawing power, you can turn off that circuit from anywhere.
Smart Panel Options in NJ: Span, Leviton, and Siemens ECOB
Three products dominate the smart panel category for residential installs in northern NJ right now:
Span Panel is the best-known smart panel — a purpose-built device with an intuitive app, strong EV integration (Span has a partnership with Ford and works natively with most Level 2 charger brands), and robust battery backup management. It's available in a 200A configuration and supports up to 32 individual smart circuits. The hardware alone runs $3,500 – $4,500; installed in NJ with permit and inspection, expect $5,500 – $8,000.
Leviton Load Center with Smart Breakers takes a modular approach — it's a standard panel that works with Leviton's smart breaker lineup, so you can add circuit-level monitoring to an existing or new panel without replacing everything. This is often the more affordable path if you only want monitoring on a subset of circuits. Installed costs are typically $2,500 – $5,000 depending on circuit count.
Siemens ECOB is the newest entrant, backed by a major panel manufacturer, with deep integration into home energy management systems. It's a strong choice if you're building new or doing a full rewire. Pricing is comparable to Span.
Who Actually Needs a Smart Panel?
Here's our honest answer, based on the homes we work in across Hudson and Essex County:
Smart panels make the most sense when you have two or more of the following:
- An EV (or planning one soon) and you want to maximize overnight charging without tripping breakers or paying for unnecessary panel expansion.
- Solar panels or battery storage — smart panels give you granular control over which loads draw from batteries versus the grid, maximizing the value of your stored energy.
- A heat pump as your primary heating system, especially in a home where you're also running other high-load appliances. Load management between systems saves money and prevents nuisance trips.
- A backup power requirement — smart panels dramatically improve the usefulness of a battery backup system by intelligently shedding non-critical loads rather than requiring you to manually manage it.
Smart panels are probably not necessary if: you have a conventional home without EVs, solar, or a heat pump; you just want a modern, reliable panel; or you're on a tight budget where that money is better spent on the panel upgrade itself.
A well-installed traditional 200A electrical panel from Square D or Siemens will serve most NJ homes reliably for 30+ years. Don't feel pressured into smart panel features you won't use.
Smart Panel Costs in NJ (2026)
Here's a realistic cost breakdown for smart panel installation in northern NJ:
- Span Panel (full install, 200A): $5,500 – $8,000, including hardware, labor, permit, and inspection.
- Leviton modular smart panel (new install): $3,000 – $5,500 depending on circuit count and panel location.
- Siemens ECOB (full install): $5,000 – $7,500.
- Adding a traditional 200A panel without smart features: $2,000 – $4,500. This remains the right choice for most homeowners.
In all cases, the permit is required in NJ and inspections are standard. Smart panels don't change the permit requirement — they just add a layer of commissioning work after the inspection.
NJ doesn't currently offer specific rebates for smart panels, but if the smart panel is installed as part of a broader electrification project (heat pump + EV charger + panel), the panel portion may qualify under the PSE&G Whole Home program or federal IRA credits. Check our FAQ for more on how rebates interact with panel upgrades.
Smart Panel Integration with Tesla Powerwall, Enphase, and EV Chargers
Where smart panels really shine is as the hub of a whole-home energy system. If you have or are planning solar plus battery storage, a smart panel turns a collection of independent devices into a coordinated system.
With a Span panel paired with a Tesla Powerwall, for example, you can set up automatic load management that: charges your EV when solar production is high and battery is full → shifts to grid only during off-peak hours → drops non-critical loads automatically during a grid outage → keeps your critical circuits running until battery is depleted. That level of automation isn't possible with a traditional panel, regardless of how good the individual devices are.
We also install and wire smart home electrical systems more broadly — if you're thinking about whole-home automation, smart switches, or integrating your electrical system with a home hub, that's work we do regularly.
If you're weighing a smart panel for your NJ home and want a straight answer on whether it makes sense for your specific situation, give us a call.
