Quick Answer
Smart electrical panels replace or supplement your breaker box with real-time circuit monitoring, remote control, and solar/battery integration. NuWatt engineers ranked 9 panels for 2026 — Schneider Square D leads at 88/100, followed by SPAN Panel (86/100) and Eaton Brightlayer (82/100). Seven of nine panels are UL 3141 certified, enabling NEC 2026 service upgrade avoidance and saving homeowners $2,500–$5,000 on electrical upgrades. Prices range from $1,200 (Enphase IQ Load Controller) to $12,000 (Savant Power System). NuWatt installs SPAN and Lumin across New England and Texas.

Get a Free RecommendationA smart electrical panel is the next evolution of your home's breaker box. Instead of simple circuit breakers, it features intelligent circuits that monitor, manage, and optimize your home's energy in real time.
See exactly how much energy each circuit uses — from your HVAC system to your kitchen appliances. Identify energy hogs and track usage patterns over time.
Turn individual circuits on and off from your phone. Set schedules, create automation rules, and prioritize critical loads during backup power events.
Automatically route excess solar to your EV charger, manage battery discharge during peak rates, and maximize self-consumption — all without manual intervention.
Under NEC 2026 Article 705, a UL 3141-certified smart panel can substitute for a full utility service upgrade when you add an EV charger or heat pump. Instead of upgrading from 100A to 200A service ($2,500–$5,000), the panel dynamically allocates capacity between loads in real time.
Seven of the nine panels we ranked hold UL 3141 certification. Leviton and Generac PWRmanager were still pursuing it as of April 2026.
| Feature | Smart Panel | Traditional Panel |
|---|---|---|
| Energy Monitoring | Per-circuit real-time data | None |
| Circuit Control | Remote on/off via app | Manual breaker only |
| Solar Integration | Automatic optimization | Basic connection only |
| Battery Backup | Intelligent load shedding | Manual transfer switch |
| EV Charging | Dynamic load management | Dedicated circuit required |
| Service Upgrade | Often avoidable (UL 3141) | Required for new loads |
| Cost | $1,200–$12,000 hardware | $1,500–$3,000 replacement |

Learn moreA smart panel with load management can accommodate a heat pump without a service upgrade.
Learn moreA smart electrical panel replaces or supplements your traditional breaker panel with one that monitors energy usage per circuit, allows remote control of individual circuits, and integrates with solar, batteries, and EV chargers. Think of it as the brain of your home energy system — it can automatically manage loads during outages, optimize solar self-consumption, and show you exactly where every watt of electricity goes.
Not necessarily, but a smart panel significantly enhances your solar investment. It lets you see exactly how your solar energy is being used circuit by circuit, can prioritize solar-charged battery backup for critical loads during outages, and can route excess solar to your EV charger instead of sending it back to the grid. If you have solar + battery + EV, a smart panel ties them all together.
Smart panels range from $1,200 to $12,000 for the equipment, plus $500–$2,000 for professional installation. The SPAN Panel (the most popular option NuWatt installs) typically costs $5,500–$8,000 installed. Budget options like the Enphase IQ Load Controller start around $1,200–$1,800 for load management within the Enphase ecosystem. Premium systems like Savant can exceed $10,000.
In many cases, yes. Smart panels certified under UL 3141 — like SPAN and Lumin — can dynamically manage loads to avoid exceeding your panel capacity under NEC 2026 Article 705. This means you may not need to upgrade from 100A to 200A service when adding an EV charger or heat pump, saving $2,500–$5,000 in utility upgrade costs. However, the UL 3141 panel only substitutes for the upgrade — if your existing panel is outdated or unsafe, replacement is still recommended.
UL 3141 is the safety listing for interactive Home Energy Management Systems (iHEMS) — smart panels that actively manage loads to prevent overloads. Under NEC 2026 Article 705, a UL 3141-certified panel can substitute for a full utility service upgrade when adding new high-draw loads like EV chargers or heat pumps. SPAN, Lumin, Schneider Electric, Eaton, Savant, and Enphase are all UL 3141 certified. Leviton and Generac PWRmanager had certification pending as of April 2026.
Smart panels paired with battery storage (like Tesla Powerwall or Enphase IQ Battery) are designed to shine during outages. They automatically disconnect from the grid, prioritize critical loads (refrigerator, lights, medical equipment), and shed non-essential circuits to extend battery runtime. Without a battery, most smart panels do not provide backup power on their own.
