SPAN Smart Electrical Panels — Smarter Power for Puget Sound Homes

SPAN replaces the breaker box with a metered, app-controlled panel that manages every circuit in real time — the electrification centerpiece.

When Greater Seattle and Puget Sound homeowners electrify, add solar, or plan for reliable backup power during storm season, the electrical panel becomes the single most important piece of home infrastructure. The SPAN Smart Electrical Panel replaces a conventional breaker box with an intelligent, circuit-level control center that meters, monitors, and controls every circuit in your home from your phone or tablet. Installed by Eco Electric, Plumbing, Heating & Air — Washington's Home Energy Expert — a SPAN panel gives you safety, control, and resiliency built for the Pacific Northwest.

What a SPAN panel actually does — try it

Flip circuits on and watch the panel hold a whole all-electric evening inside a 100-amp service — the same load management logic a SPAN install brings to your home.

Utility power lands at the meter and main panel, then splits into every branch circuit. Panel capacity, breaker quality, and AFCI/GFCI protection set the safety ceiling for everything else in the house — Washington enforces the NEC's arc-fault rules here (WAC 296-46B).

Western Washington fit

Why SPAN makes sense here — specifically

Purpose-built for the Puget Sound electrification path: heat pump + EV + induction on an existing 100–125A service, plus storm-season backup control.

  • Load management lets many Seattle and Everett homes electrify without waiting on a utility service upgrade.
  • Circuit-level backup control stretches battery runtime through multi-day windstorm outages.
  • Pairs with Seattle City Light and PSE time-of-day habits — see exactly which circuits drive the bill.

What it costs, honestly

SPAN against Eco's published ranges

Eco installs smart panel systems for $6,000–$12,000 depending on panel size and breaker package — often instead of an $8,000–$16,000 100A→200A service upgrade when the load calculation allows.

By home type

Which Washington homes SPAN fits best

Great fit

Pre-1950 craftsman

Wallingford · Ballard · Queen Anne

Old 60–100A services are the classic electrification bottleneck — a SPAN panel plus load management often avoids the full service upgrade and its utility coordination.

Great fit

1960s–80s rambler with ducts

Typically 100–125A service: SPAN meters the real load so a heat pump and EV charger ride the existing service safely.

Good fit

New construction / townhome

New 200A services rarely need load management — buy SPAN here for monitoring, backup control, and solar-readiness rather than capacity.

Good fit

Large multi-system home

Two coordinated panels handle homes beyond 48 circuits — sized during the load assessment.

Why a SPAN Panel matters in the Pacific Northwest

Pacific Northwest homes face unique energy challenges: dense urban electrification in Seattle, rising EV adoption, increasing home electrification (heat pumps, induction ranges), frequent wind and winter storms that can cause outages, and growing interest in solar-plus-storage. The SPAN Smart Electrical Panel addresses these directly:

  • Circuit-level visibility: See real-time energy use by circuit (heat pump, dryer, EV charger, HVAC, water heater, lights) to identify the biggest energy draws and optimize use in a temperate-but-variable climate like ours.
  • Intelligent load management: Prioritize critical loads during outages (refrigerator, medical equipment, heat pump, well pump) when paired with a battery. SPAN lets you decide which circuits stay on so your family remains comfortable and safe.
  • Solar and battery integration: SPAN integrates with rooftop solar and most home battery systems (including popular systems like Tesla Powerwall), enabling smarter charging, peak shaving, and greater solar self-consumption even on cloudy Puget Sound days.
  • EV-friendly charging: Schedule and limit EV charging to off-peak hours or when solar production is highest, reducing charging costs and avoiding panel overload.
  • Improve safety & reduce trips: SPAN’s digital control prevents nuisance trips and speeds diagnosis. Remote control and alerting help you react to problems before they become emergencies during severe weather.
  • Future-proof for electrification: SPAN enables safe load shifting as you add high-demand electrified appliances in your Seattle-area home without costly oversized service upgrades.

Benefits homeowners actually feel

  • Lower, smarter bills: Use SPAN’s real-time metering and scheduling to shift discretionary loads to cheaper hours, and maximize solar output when paired with batteries.
  • Greater resiliency during outages: Manually or automatically prioritize the circuits that matter most, keeping the essentials powered until grid service returns.
  • Clear path to electrification: Avoid guesswork when adding EV chargers, heat pumps, or induction cooking—SPAN helps you plan and safely manage capacity.
  • High home value and modern convenience: Circuit-level control, energy transparency, and integrated backup increase appeal to buyers who expect smart, resilient homes.
  • Reduced risk and faster troubleshooting: See which circuit caused an issue, reset or remotely isolate loads, and reduce the need for emergency service calls.

Frequently asked Puget Sound homeowner questions

Will SPAN work with my existing solar and battery?

Yes. SPAN is designed to integrate with most solar inverters and battery systems, improving solar self-consumption and enabling prioritized backup during outages. Eco will confirm compatibility during your free assessment and handle system coordination.

How long does an install take?

Typical panel replacements take a day or two, including testing and app setup. Complex integrations with battery systems or service upgrades may take longer. Your detailed timeline will be included in our proposal.

Do I need a service upgrade?

Not always. We evaluate your current service (100A, 150A, 200A) and your electrification goals. If a larger service is needed, Eco manages the full upgrade and permitting process.

Can SPAN help reduce my energy bills with Seattle City Light or PSE time-of-use rates?

Yes. SPAN enables scheduling and load shifting to lower-cost hours and can help offset peak demand when paired with batteries and solar.

The honest part

Choose something else instead if…

No brand wins every home. We install and service the alternatives too — so the recommendation follows your house, not a quota.

Choose Square D or Eaton if you need dependable capacity, not intelligence — a conventional 200A panel replacement costs less and the hardware warranties are longer.

Choose Tesla if backup batteries are the priority and you're deep in the Tesla ecosystem — Powerwall 3 brings its own load intelligence.
