Your Local SPAN Panel Installer in Hercules and Nearby Cities

If you are looking for a SPAN panel installer Hercules homeowners can count on, AC3 Electric is right in your neighborhood. Your electrical panel is the heart of your home's power system, and many Bay Area homes still run on older panels that were never designed for today's loads: EV chargers, heat pumps, induction ranges, solar, and home batteries. A SPAN smart panel replaces that old breaker box with a connected panel you can monitor and manage from your phone.

We handle the whole project, from the first assessment through permits, utility coordination, installation, and app setup, so you get a safe, code-compliant upgrade without the guesswork.

What Is a SPAN Smart Panel?

A SPAN smart panel El Cerrito and Bay Area homeowners are choosing is a modern replacement for a traditional electrical panel. Instead of a row of breakers you only touch when something trips, SPAN gives you visibility and control over individual circuits through the SPAN app.

Key Benefits

Circuit-level monitoring: See how much energy each circuit uses, so you can spot energy hogs and understand your bill.
Control from the app: Turn many circuits on or off remotely and set priorities for which loads matter most.
Solar and battery integration: SPAN is designed to work with solar and home battery systems, helping you decide which circuits stay powered during an outage.
EV charger ready: SPAN can integrate with EV charging, including SPAN's own charger, to manage charging alongside the rest of your home's demand.
Load management: In some homes, SPAN's load management features can make it possible to add new electric loads without upgrading your utility service. Whether that applies to your home depends on your existing service and planned loads, which we evaluate on site.

Features and compatibility vary by SPAN product and equipment. We'll confirm what works for your specific home during the assessment.

Our SPAN Panel Installation Process

Assessment. We review your existing panel, electrical service, wiring, and your goals, whether that's solar, a battery, an EV charger, or simply better control. We'll tell you honestly whether a SPAN panel is a good fit.
Permits. We pull the required electrical permit with your local building department, whether that's your city or Contra Costa County for unincorporated areas, and schedule inspections.
PG&E coordination. When your project needs a utility disconnect and reconnect, or involves solar or battery interconnection, we coordinate with PG&E.
Installation. We remove the old panel, install your SPAN panel, connect and label circuits, and make sure everything meets code and passes inspection.
App setup. We help you set up the SPAN app, name your circuits, and walk you through monitoring and control so you're comfortable from day one.

SPAN Panel FAQ

What is a SPAN smart panel?

A SPAN panel is a smart electrical panel that replaces a traditional breaker panel. It lets you see energy use circuit by circuit and switch many circuits on or off from the SPAN app, and it is designed to work with solar, home batteries, and EV chargers.

Will a SPAN panel let me avoid a main service upgrade?

In some homes, yes. SPAN's load management features can help add loads like an EV charger or heat pump without increasing the size of your utility service. Whether that works for your home depends on your existing service, your planned loads, and local code requirements, which we review during the assessment.

Do I need a permit to install a SPAN panel?

Yes. Replacing an electrical panel requires a permit and inspection from your local building department, such as the City of Hercules, El Cerrito, Pinole, San Pablo, Richmond, or Berkeley, or Contra Costa County for unincorporated areas like El Sobrante. AC3 Electric handles the permit process for you.

Does PG&E need to be involved?

Often, yes. Many panel replacements require PG&E to disconnect and reconnect power at the meter, and solar or battery changes may involve PG&E interconnection steps. We coordinate with PG&E when it is needed for your project.

How long does a SPAN panel installation take?

The installation itself is typically completed in about a day for many homes, though timing depends on your home's wiring, permit scheduling, and any PG&E appointments. We give you a clear timeline after the on-site assessment.
