SPAN panel replaces your existing electrical panel, so this is a full panel swap. Our electricians typically complete the install in 6-8 hours. We move every circuit from the old panel to SPAN, label everything in the app, and set up backup priorities. The result is a fully intelligent panel where you can see exactly what's using power and remotely control any circuit.
Lumin installs alongside your existing electrical panel — no panel swap required. Our electricians wire the circuits you want to manage through the Lumin module, typically in 3-4 hours. This is a big advantage over SPAN when the existing panel is in good shape and doesn't need replacement. We select the 12-18 most important circuits (fridge, lights, well pump, HVAC, etc.) for smart management. The app-based control works well, though we miss SPAN's built-in touchscreen.
