A smart electrical panel does a lot more than a standard panel upgrade, and choosing between Span, Lumin, and Leviton usually comes down to what your existing panel looks like and what you actually want to control. This guide compares all three on real functional differences, not marketing copy.
What Is a Smart Electrical Panel, and How Is It Different From a Standard Upgrade
A standard panel upgrade increases capacity and replaces aging equipment, but it does not give you visibility into what is happening on individual circuits. A smart panel adds circuit-level monitoring and, on some systems, remote control through an app, plus automated load management that can prioritize which circuits stay powered during an outage. That last feature matters most for homeowners pairing solar or battery storage with the panel.
Span Panel: Features, Cost, and Best Fit
Span replaces your existing panel entirely, giving you full circuit-level app control and the deepest integration with solar, battery, and EV systems currently on the market. Because it is a complete panel swap, the installation itself and the hardware cost both run higher than the alternatives here. It is the strongest option for someone planning a full electrification project, not just a monitoring upgrade.
Lumin Panel: Features, Cost, and Best Fit
Lumin installs alongside your existing panel rather than replacing it, wiring in a set number of the circuits you actually want to manage, typically the highest-draw ones like HVAC, the water heater, and a dryer. That makes it the faster, less disruptive install of the three when your current panel is in good shape and does not need replacing anyway. It is a strong middle-ground pick for backup power prioritization without the cost of a full panel swap.
Because Lumin does not touch your main service equipment, it is also a reasonable option if your existing panel is relatively new and you simply want smarter visibility layered on top of it. The tradeoff is that circuits you did not choose to wire into the system remain standard, unmonitored circuits, so it works best when you can clearly identify which loads actually matter to you during an outage or a high-usage month. Most homeowners land on a short list without much difficulty: the refrigerator, a home office setup, and whichever appliance tends to drive the biggest spike on the monthly bill. Once that list is set, the installation itself is straightforward for a licensed electrician, since it mostly involves rerouting those specific circuits through the Lumin module rather than touching the rest of the panel.
“If your panel is only a few years old and in good condition, ripping it out just to add smart features is usually not the right move. That is exactly the situation Lumin was built for.”

Leviton Smart Panel: Features, Cost, and Best Fit
Leviton takes a different approach, using smart circuit breakers added into a familiar, traditional load center rather than a proprietary panel. It is the simplest and generally most affordable path to circuit-level monitoring, though it trades some of Span’s deeper automation for that simplicity. For homeowners who mainly want visibility into power use rather than full remote control, it is often the more practical starting point.
| Brand | Install Type | Best Fit |
|---|---|---|
| Span | Full panel replacement | Homeowners who want full per-circuit app control and deep solar/EV/battery integration |
| Lumin | Installs alongside existing panel, no swap needed | Homes with a panel in good condition that just need selected circuits managed |
| Leviton | Smart breakers added to a traditional load center | Homeowners who want smart monitoring at a lower cost and simpler install |
Is a Smart Panel Worth It? Who Should Get One
If you are planning solar, a home battery, or EV charging and want the system to automatically manage load during an outage, a smart panel earns its cost. If you just want a modern, reliable panel without those extras, a standard panel upgrade covers the safety and capacity side for less money. Hardware pricing for Span, Lumin, and Leviton is set by the manufacturer, not by Electrical Land, so treat any cost figure you see online as a starting reference and confirm it with a current quote before deciding.
Genuinely Unbiased: Why This Comparison Avoids Picking a Winner
None of these three systems is objectively “best” independent of your home and goals, which is why this guide compares them on fit rather than crowning one winner. A homeowner doing a full electrification project with solar, battery, and EV charging has very different needs than someone who just wants to know which circuit spiked their bill last month. Talk through your actual goals with an electrician before picking a brand, since the install type alone (full swap versus add-on) often narrows the decision more than any feature list does.
What Installation Involves and What to Budget
Electrical Land’s own labor for smart home integration work starts from $200, separate from whatever hardware you choose. A standard panel upgrade, which some homeowners use as the baseline comparison point, starts from $850. Installation timing depends heavily on which system you pick, since a full Span swap takes longer than adding Lumin or Leviton to an existing setup.
