SPAN, Leviton, and Lumin smart panel installation in Essex County, MA. Real-time energy monitoring, circuit-level control, and seamless integration with solar, battery, and EV charging — installed by certified electricians who've done this since 1984.
A smart panel replaces your conventional circuit breaker panel with an intelligent load management system. Instead of a dumb box of breakers you flip manually, a smart panel gives you visibility and control over every circuit in your home — in real time, from your phone.
Where a standard panel can only tell you "power is on or off," a smart panel tells you exactly how much power each circuit is drawing, which circuits are running, and lets you turn individual circuits on or off remotely — automatically or on demand.
Per-circuit usage data updated every few seconds. See exactly what's drawing power and when.
Automatically prioritize critical loads when grid power fails and you're running on battery.
Shift loads to run when your solar panels are producing — reduce what you export and buy.
Charge your EV only when grid rates are lowest or solar production is highest.
Three smart panel brands dominate the market — with meaningfully different price points, capabilities, and ideal use cases. The price differential between SPAN and Leviton is roughly 3–5x, but SPAN delivers a substantially more capable product. Here's the honest comparison:
| Feature | SPAN Panel | Leviton Load Center | Lumin Smart Panel |
|---|---|---|---|
| Typical installed cost | $4,500–$6,500 | $1,200–$2,000 | $2,500–$4,000 |
| Circuit-level monitoring | ✔ All circuits, real-time | ✔ All circuits | ✔ All circuits |
| Remote circuit control | ✔ Individual circuit on/off | Limited | ✔ Individual circuit on/off |
| Solar integration | ✔ Native, seamless | ✔ Compatible | ✔ Compatible |
| Battery/backup integration | ✔ Best-in-class | Basic | ✔ Strong |
| EV load management | ✔ Advanced scheduling + optimization | Basic | ✔ Good |
| App quality | Best-in-class | Good | Good |
| Best for | Solar + battery + EV homes; maximum control | Budget-conscious; basic monitoring | Mid-range; strong energy management |
💡 Our honest take: If you have solar, a battery, and an EV — or plan to — SPAN earns its premium. The intelligence it adds to your energy system pays back over time. If you're primarily interested in monitoring and basic control without the full ecosystem, Leviton delivers at a fraction of the cost. We'll recommend the right fit for your home, not the most expensive one.
A smart panel is most powerful when paired with solar, battery storage, and EV charging. Without circuit intelligence, those systems operate independently — your solar might export to the grid while your EV charges from it, literally paying for power you're producing. A smart panel coordinates everything:
The panel shifts high-draw loads (laundry, dishwasher, EV charging) to run during peak solar production hours — maximizing what you consume from your own generation and minimizing grid export.
When the grid goes down, the panel automatically identifies which circuits to keep alive based on your priority settings — fridge, medical equipment, phone charging — and sheds non-essentials to extend runtime.
Smart panels prevent EV charging from overloading your service during peak household draw. They can schedule charging to off-peak hours when electricity rates are lower, or to coincide with solar production.
Monthly reports break down your usage by category. You'll quickly identify the actual energy hogs — the always-on circuits drawing power invisibly around the clock.
The average smart panel owner identifies 15–20% unnecessary energy consumption within the first month of monitoring data. That's real money — not just technology for technology's sake.
Smart panels are not standard electrician work. SPAN, Leviton, and Lumin all require installation by certified electricians who've completed manufacturer training — for good reason. These systems involve precise load calculations, proper bus connections, integration with solar inverters and battery systems, and firmware configuration. An uncertified installer who "figures it out" is going to cost you more in callbacks than a proper certified installation would have.
John Zolotas started this company in 1984 as a straightforward residential electrician. His son Greg has expanded that into electrification — adding smart panel, heat pump, and solar capabilities — but the operating philosophy hasn't changed: do the job right, pull the permit, pass the inspection, stand behind the work.
We're not a national franchise that trains installers for two weeks and sends them into your home. We're local. When something needs attention after the job, you get Greg on the phone.
