Quick answer
A traditional 200A panel upgrade buys raw capacity — more amps, more breaker spaces, done. A SPAN smart panel buys intelligence: per-circuit monitoring and control from an app, load management that can add an EV charger or heat pump without a utility service upgrade, and built-in readiness for solar and battery backup. Electrifying homes and outage-prone neighborhoods get the most from SPAN; a straightforward capacity problem is often still best solved the traditional way.
- Traditional 200A upgrade: proven, cheaper, and the right fix when you simply need more capacity and breaker spaces.
- SPAN smart panel: meters and controls every circuit from your phone, and its load management can defer a costly utility service upgrade.
- Planning solar, battery backup, or an EV? SPAN integrates all three and lets you choose which circuits stay on during an outage.
- Eco is an authorized SPAN installer — and licensed for conventional panel work — so we quote both without a thumb on the scale.
Use this guide when
Your panel is full or aging, an EV charger or heat pump quote came back with 'panel upgrade required,' you're planning solar or battery storage, or storm-season outages have you thinking about backup power. The panel decision shapes every electrification step after it, so it's worth getting right once.
What actually drives the decision
Where your home is headed. If the next decade holds an EV, a heat pump, induction cooking, or solar-plus-battery, the smart panel's control layer keeps paying. If you need capacity for a hot tub and nothing else is changing, conventional wins on simplicity and price. Utility service size matters too — SPAN's load management can make a 100A or 125A service behave bigger, which is sometimes the whole ballgame.
Compare your options
Choose a traditional 200A upgrade when
You need capacity and breaker spaces, your loads are conventional, and app-level circuit control isn't worth a premium to you. It's the industry-standard fix: new panel, new main breaker, utility coordination, permit, and inspection — decades of service with zero software.
Choose a SPAN smart panel when
You're electrifying (EV, heat pump, induction), adding solar or a battery, or you want circuit-level visibility and outage control. SPAN's load management can let big new loads ride on your existing service — avoiding the cost and utility lead time of a service upgrade — and when paired with a battery, you choose exactly which circuits stay on.
Sometimes the answer is both
Homes doing a full electrification push occasionally pair a service upgrade with SPAN — capacity plus control. That's the most future-proof (and most expensive) path; a load calculation tells us whether it's actually necessary or just nice.
What does each option cost installed in the Seattle area?
Panel work is where quotes vary most, because the panel itself is only part of the job — service condition, grounding, and code corrections ride along. These ranges match our published Puget Sound panel cost guide; smart-panel installs add hardware and integration.
| Option | Typical installed range | What that covers |
|---|---|---|
| Traditional 200A panel upgrade | $5,000–$12,000 | New load center, main breaker, grounding/bonding corrections, utility coordination, permit, and inspection. |
| SPAN smart panel | $8,000–$15,000 | SPAN hardware, installation, app setup, and integration with existing circuits — more when solar/battery commissioning is part of the project. |
What changes the price
- Service size and condition: if the utility service entrance needs work, cost and lead time rise for either option — SPAN sometimes avoids this entirely via load management.
- Code corrections: grounding, bonding, AFCI/GFCI requirements, and working-clearance fixes get folded into any honest panel quote.
- Rebates: WA HEAR can put up to $4,000 toward a panel upgrade and $2,500 toward wiring when they enable electrification (income-eligible).
- Integration scope: EV charger circuits, battery hookup, or solar interconnection commissioned at the same time widen the range.
- Permits and utility coordination: required in every Puget Sound jurisdiction — timelines vary by city and by PSE/Seattle City Light queue.
Ranges are representative Seattle / Puget Sound installed prices, not a quote — your home's specifics set the real number. Eco gives you an upfront price before any work begins.
How do they work differently?
How a traditional panel works
A conventional panel is a passive distribution point: power enters through the main breaker and splits across circuit breakers that do exactly one thing — trip on overload or fault. It has no idea what each circuit is drawing, no memory, and no controls. Capacity is fixed by the main breaker and the utility service behind it; when loads outgrow it, the fix is a bigger panel and often a bigger service.
How a SPAN smart panel works
SPAN replaces the passive panel with a metered, software-controlled one: every circuit is monitored in real time and controllable from an app. That intelligence lets it actively manage loads — briefly easing an EV charger while the dryer and heat pump run — so total demand stays inside your existing service. Paired with solar and a battery, it decides which circuits stay live in an outage and stretches backup runtime by shedding what you don't need.
Pros and cons, honestly
SPAN smart panel
Pros
- Per-circuit energy monitoring and app control
- Load management can avoid a utility service upgrade (and its lead time)
- Built for solar, battery, and EV integration — prioritize circuits during outages
- Finds waste: real-time visibility into what's driving your bill
- Future-proofs the electrification steps that come next
Cons
- Higher installed cost than a conventional swap
- Software-dependent features (core protection still works like any panel, but the smarts need the app/network)
- Newer product category — fewer electricians service it (Eco is an authorized installer)
- Overkill for homes with no electrification or backup plans
Traditional 200A panel
Pros
- Lower cost, industry-standard hardware
- Any licensed electrician can service it for decades
- No software, no app, nothing to update
- Solves pure capacity and safety problems (fuse boxes, recalled panels) cleanly
Cons
- No visibility — you learn about problems when a breaker trips
- No load management: big new loads may force a utility service upgrade anyway
- Backup power needs separate transfer equipment and offers no circuit-level choice
- Adding solar/battery later means additional interconnection hardware
Key terms and context
This guide is written for electrical decisions in the Puget Sound. It uses the same terminology you'll hear from inspectors, technicians, and permit offices.
Buying capacity when the problem was management
Homes get quoted a full service upgrade — with utility fees and weeks of lead time — when a load calculation shows a smart panel could manage the same loads on the existing service. Run the numbers before defaulting to bigger wire.
Buying intelligence nothing will use
The reverse mistake: paying the SPAN premium in a home with no EV, no solar plans, and no outage concerns. If none of the smart features map to your actual next five years, the conventional panel is the honest recommendation — and the one we'll make.
How we build this guidance
- Eco is an authorized SPAN dealer and installer with integration experience across solar, batteries (including Tesla Powerwall), and EV charging in Puget Sound homes.
- We're equally licensed for conventional panel and service work — the recommendation follows your load calculation, not our inventory.
- Every panel quote includes the code corrections and utility coordination Seattle-area jurisdictions actually require.
Methodology: Comparison based on SPAN manufacturer documentation, NEC load-calculation provisions for managed loads, Eco's SPAN and conventional panel installs across the Puget Sound, and 2026 WA HEAR program rules. Install ranges align with Eco's published panel cost guide.

Common questions
Can a SPAN panel really let me skip a service upgrade?
Often, yes. SPAN's load management keeps total demand inside your existing service by intelligently pacing flexible loads like EV charging — NEC provisions recognize managed loads in the calculation. Whether it works for your home comes down to a load calc, which is the first thing we run.
Does SPAN work with Tesla Powerwall and rooftop solar?
Yes — SPAN is designed to integrate with most solar inverters and home batteries, including Tesla Powerwall. Paired with a battery, you choose which circuits stay on during an outage and can stretch backup runtime by shedding non-essentials from your phone.
What happens to a SPAN panel if the internet goes down?
It keeps protecting and powering your home like any panel — breaker-level safety doesn't depend on connectivity. You temporarily lose remote app control and live monitoring until the connection returns; local operation continues.
Do rebates apply to panel work?
Washington's HEAR program can put up to $4,000 toward a panel upgrade and up to $2,500 toward wiring for income-eligible households when the work enables electrification (a heat pump, EV charger, or similar). We confirm eligibility and handle paperwork at the estimate.
Is a smart panel safe? Is it code-compliant?
Yes — SPAN panels are UL-listed and installed to the same NEC and Washington state requirements as any panel, with permit and inspection. The 'smart' layer adds monitoring and control on top of conventional breaker protection; it doesn't replace it.
