SPAN Smart Panel Cost & Installation Guide (CT, 2026)
A SPAN smart panel installed in Connecticut runs $5,500–$8,000 all-in on a typical 200A single-family home. That covers the panel hardware, install labor, permit, and inspection. Whether it’s actually worth that vs. a standard panel comes down to one question — are you running solar, an EV, or planning to add a battery? Here’s the full breakdown, written by Tyler Faye, CT-licensed master electrician who installs SPAN panels in Eastern Connecticut.

What Is a SPAN Smart Panel?
A SPAN smart panel is a direct replacement for your home’s main breaker panel. Same job — distributes power from the utility service to all your circuits. Same physical footprint as a standard 200A panel. But every individual circuit is monitored in real time, controllable from a phone app, and can be remotely turned on/off or load-shed automatically when the grid goes down.
The hardware is built around solid-state relays instead of mechanical breakers, plus a built-in energy management computer that tracks consumption per circuit at second-level resolution. The result is a panel that knows your dryer runs every Sunday at 7 PM, your EV pulls 9.6 kW from 11 PM to 4 AM, and your well pump drew 4 kW for 90 seconds at 6:14 this morning.
What you actually get
- Real-time circuit-level energy monitoring (every circuit, every second)
- Remote control of every circuit via app — turn off the basement fridge while on vacation
- Automatic load shedding when on backup battery or generator
- Native integration with Tesla Powerwall, Enphase, SolarEdge, and most EV chargers
- Time-of-use optimization — automatically shift loads to off-peak Eversource hours
- Backup-power priorities — pick which circuits stay live during an outage
SPAN Panel Cost Breakdown
Here’s what a typical installed cost looks like for a CT single-family home swapping from a standard 200A panel to SPAN. Costs vary by home; this is the middle of what we’ve quoted in Tolland and Hartford counties.
| Line Item | Cost Range | Notes |
|---|---|---|
| SPAN Panel Hardware | $3,500–$4,500 | 200A model. 400A runs higher. |
| Install Labor | $1,800–$3,000 | Swap labor + re-termination of branch circuits |
| CT Electrical Permit | $150–$300 | Varies by town |
| Eversource Coordination | $0–$250 | Meter pull / reset scheduling |
| Typical Total (CT) | $5,500–$8,000 | All-in installed cost |
Add-ons that push the total higher: service-mast replacement if the existing one is undersized or rusted ($800–$1,500), a service upgrade from 100A to 200A if your home isn’t already there ($1,500–$3,500 — see our panel upgrade page), or a sub-panel addition.
SPAN vs. Traditional 200A Panel
Most CT homes we work on have a standard Square D, Eaton, or Siemens 200A panel — proven, code-compliant, and cheap. SPAN does everything those panels do, plus a lot more. Here’s the side-by-side.
| Feature | Traditional Panel | SPAN |
|---|---|---|
| Installed Cost (CT) | $2,000–$3,500 | $5,500–$8,000 |
| Circuit Monitoring | None | Every circuit, real-time |
| Remote Circuit Control | None | Via app |
| Mobile App | iOS + Android | |
| Solar Integration | External monitor required | Native (Enphase, SolarEdge, Tesla) |
| Battery Backup Compatible | Yes, with separate transfer switch | Built-in load shedding for batteries |
| EV Charger Load Management | Automatic | |
| Warranty | 5–10 years | 10 years |
| Install Time | 4–8 hours | 4–8 hours |
| Code-Compliant in CT |
Is SPAN Worth It?
We get this question on every SPAN estimate. The honest answer depends on what else is on your electrical roadmap.
Yes — SPAN is worth it if:
- You have or are adding solar PV
- You have or are adding an EV charger (especially two EVs on one service)
- You’re planning a battery backup like Tesla Powerwall or Enphase IQ Battery
- You’re on the Eversource time-of-use rate and want automated load shifting
- You want to defer a service upgrade — SPAN’s load management can let a 100A or 200A service handle more
- You like data — circuit-level monitoring is genuinely useful for spotting phantom loads and failing appliances
No — stick with a traditional panel if:
- You just need to swap an aging panel for code/insurance reasons
- You have no plans for solar, EV, or battery
- You’re budget-constrained — the $3,000–$4,500 premium over a standard panel is real
- Your home has spotty Wi-Fi to the panel location (basement Wi-Fi is a common issue)
- You’re selling within 12–24 months — payback is mostly through years-of-use savings
How SPAN Integrates with EV Chargers and Solar
This is where SPAN earns its price. The panel actively manages power flow between your utility service, solar production, battery, and high-load appliances based on rules you set in the app.
EV charger load balancing
On a 200A service, running a 48A EV charger plus electric dryer plus electric range simultaneously can trip the main breaker. SPAN watches the total service load in real time and momentarily throttles the EV charger when other big loads kick on. The car still charges — just slightly slower for those 20 minutes. You don’t notice and you don’t need a service upgrade.
For homes with two EVs, SPAN can intelligently allocate amperage between them based on which car needs to leave first. We’ve set this up for clients in Manchester and Vernon — works as advertised.
Solar + battery + time-of-use
Eversource’s time-of-use rate is meaningfully cheaper during off-peak hours. SPAN can automatically:
- Charge your battery from solar during the day
- Pull from the battery during peak rate hours instead of the grid
- Charge the EV only during off-peak hours (which also helps with the Eversource Managed Charging Program bonus credits)
- Run electric hot water and pool pumps at the cheapest hours
Backup power priorities
In a grid outage with a battery backup, SPAN lets you pick which circuits stay live and in what order they shed if the battery runs low. Well pump and fridge stay on. Sauna and pool heater shut off first. This kind of granular backup control is something that used to require a manual transfer switch panel — SPAN does it in software.
SPAN Installation Process
Site Survey
Tyler visits, checks your existing panel, service drop, Wi-Fi coverage at the panel location, and confirms the SPAN configuration that fits your service size and circuit count.
Permit Pull
We file the electrical permit with your town and coordinate the Eversource meter pull/reset window. Permit turnaround is typically 3–7 days in Tolland and Hartford counties.
Install Day
Power off in the morning, old panel out, SPAN in, all branch circuits re-terminated, panel labeling, Wi-Fi setup, app config. Power restored same day.
Typical day-of timeline: power off around 8 AM, old panel removed by 10 AM, SPAN mounted and bonded by noon, branch circuits re-terminated and labeled by 2 PM, Eversource calls back the meter, power restored, Wi-Fi setup and app pairing wraps by 4 PM. Inspection happens the next day or the following week depending on AHJ scheduling.
On install day, we recommend keeping the fridge closed, planning around the no-power window, and making sure your home Wi-Fi router is back online before we leave so the panel can pair.
CT-Specific Considerations
Eversource service-side coordination
SPAN installs require pulling the meter, which means Eversource has to either be on-site or pre-authorize the pull. In Tolland County, the typical lead time is 1–2 weeks to get on Eversource’s schedule. We handle this end-to-end as part of our Eversource service coordination work.
CT inspector familiarity
SPAN is UL-listed (UL 67 for switchgear, UL 869A for service equipment) and has been code-compliant in CT under NEC 2020/2023 since launch. That said, some smaller-town inspectors haven’t seen one in person yet. We bring documentation to inspection so there are no surprises. Vernon, Manchester, Ellington, and Storrs inspectors have all signed off on installs we’ve done; smaller towns may take a phone call ahead of time.
Service upgrade pairing
About half the SPAN installs we quote also need a service upgrade (100A to 200A) because the home is older and isn’t ready for the load. If that’s you, we bundle the two — same permit, same Eversource visit, one trip. Total runs $7,000–$11,000 instead of two separate jobs at higher combined cost.
Code requirements
CT operates on NEC 2020 with state amendments. SPAN meets all relevant articles for service equipment, GFCI/AFCI protection on appropriate circuits, and working clearances (NEC 110.26). Wi-Fi requirement isn’t a code thing — it’s a SPAN thing, and you do need the panel online for the smart features to work, but the panel will still distribute power normally if Wi-Fi drops.
SPAN Smart Panel FAQ
Does SPAN require an app subscription?+
No. The SPAN app and core monitoring features are included with the panel — no monthly fee. Optional integrations with third-party platforms (some utility programs, some smart-home hubs) may have their own fees, but the panel itself does not.
Can SPAN retrofit an existing panel without a full swap?+
No. SPAN replaces your main breaker panel entirely — it’s a swap, not an overlay. The existing branch circuits get re-terminated into the new SPAN panel during the install. There’s no “SPAN module” that bolts on to a traditional panel.
What size SPAN do I need — 200A or 400A?+
Most CT single-family homes need the 200A model with 32 circuits. The 400A version is appropriate for larger homes (4,000+ sq ft) with solar, two EVs, electric heat pumps, and electric hot water all in play. We size it during the site survey.
Is SPAN worth it without solar?+
Honestly, mostly no. The biggest value comes from solar + battery + EV load management. Without those, you’re paying for circuit-level monitoring and remote control, which is interesting but doesn’t usually justify the premium over a $2,500 traditional panel. If you’re adding solar in the next 1–2 years, SPAN now makes sense.
What’s the warranty?+
10-year limited warranty on the panel hardware. The relays and the energy management computer are both covered. Wear-and-tear items like the included cellular modem (if you opted for one) have shorter coverage.
Does SPAN work with my generator?+
Yes. SPAN integrates with standby generators (including Generac and Kohler) and can prioritize backup-power circuits while shedding non-essentials, the same way it does with batteries.
How long do the solid-state relays last?+
Manufacturer-rated 10,000+ switching cycles per circuit. In normal residential use that’s 30+ years of expected lifetime. Mechanical breakers in traditional panels are rated similarly — SPAN’s relays are not a wear point in practice.
Can I get any rebates for SPAN in CT?+
There’s no direct SPAN-specific rebate. But because SPAN enables solar, battery, and EV integration, it stacks well with the federal residential solar tax credit (30%), CT’s solar incentive programs, and the Eversource EV charger rebate if you install a Level 2 charger on it.
