A Span Smart Panel installed costs $6,500 to $10,000 in San Diego. That’s not an add-on price, it’s a full main panel replacement, and the number surprises homeowners who assumed it was just a fancier breaker box bolted next to their existing one.
TL;DR
- Installed cost runs $6,500-$10,000: hardware is $3,500-$4,000, install labor and permit add $3,000-$6,000.
- A service or entrance upgrade on top of the swap pushes the total higher.
- The Span Panel replaces your main panel entirely and gives you app-based, per-circuit monitoring and control.
- It’s built for homes running solar and battery, where circuit-level backup prioritization actually matters.
- A permit and a licensed electrician are required. This isn’t a weekend DIY swap.
What a Span Smart Panel actually is
Span makes one product line: a smart main panel that replaces your existing panel outright. It’s not a device you add next to your current breakers, it’s the breaker box itself, rebuilt with app control and a current sensor on every circuit.
Once it’s in, you can see exactly what every circuit is drawing in real time, turn individual circuits on or off from your phone, and set priority rules for a battery backup so your fridge and internet stay up while the pool pump and dryer wait their turn. That level of control is only possible because Span sits at the main panel, seeing every circuit in the house rather than a subset of them.
This is a meaningfully bigger job than adding a smart plug or a whole-home monitor. A licensed electrician has to de-energize the service, pull the old panel, mount and wire the new one, and coordinate the SDG&E meter work the same way as any panel upgrade.
What it costs installed in San Diego
| Component | Cost |
|---|---|
| Span Panel hardware | $3,500-$4,000 |
| Install labor, permit, standard swap | $3,000-$6,000 |
| Total, straightforward swap | $6,500-$10,000 |
| Add if service/entrance upgrade is needed | $2,000-$4,000+ |
The wide range on labor comes down to what’s behind the wall. A house with an accessible 200A panel in good condition and no meter relocation is the cheaper end. A house on old 100A service, with a panel that needs to move or a meter that needs to be upgraded to handle solar and battery, lands at the higher end or above it.
Plan on the same power-off window as any panel replacement, typically 4 to 8 hours while SDG&E pulls and resets the meter. This isn’t a job you schedule around a home office day.
Why homeowners choose Span over a standard panel upgrade
A standard panel swap gets you more capacity and modern breakers. It doesn’t get you visibility into what’s actually drawing power, and it doesn’t let you control individual circuits during an outage.
Span’s real value shows up once solar and a battery are in the picture. Without circuit-level control, a home battery backs up the whole panel or nothing, and it drains fast if the AC and the EV charger are both pulling from it during an outage. With Span, you set the fridge, the internet, a few lights, and maybe the well pump as priority circuits, and everything else waits. That stretches a battery’s runtime by hours during a PSPS shutoff, which is a real regional factor here, not a hypothetical.
If you’re not running solar and battery, or don’t plan to within a few years, the per-circuit control is a nice-to-have you’re paying a premium for. A standard panel upgrade at $3,500-$6,500 does the core job of getting you off an undersized 100A panel for a lot less money. Our panel upgrade cost guide breaks down that baseline pricing.
Who this actually makes sense for
Span makes the most financial sense for three kinds of San Diego homeowners: people installing solar and battery at the same time as the panel work, people who already have solar and want battery backup with smart prioritization, and people replacing a failing panel who’ve decided to go all-in while the wall is open.
It makes less sense as a standalone upgrade if your only goal is more amperage for an EV charger or a hot tub. A standard panel handles that for thousands less. Our guide on when to upgrade your electrical panel walks through the signs a swap is overdue, smart panel or not.
Older San Diego housing stock, the 1960s through 1980s tract homes common in Clairemont, Rancho Bernardo, and older west-side Chula Vista, is the segment where this decision comes up most. Original 100A service, decades of added load, and now a solar quote on the table. That’s exactly the situation where a full panel replacement makes sense regardless of which brand goes in, and Span is worth the premium if battery backup and monitoring matter to you.
Permits and the install process
California requires a permit and a licensed electrician for any panel replacement, Span included. The city inspects the new panel, the grounding and bonding, and the SDG&E service coordination before signing off. Skipping the permit on a job this size is a serious liability, not a minor shortcut, since it touches your entire home’s electrical service.
The process runs like any panel swap: site visit and load calculation, permit pulled through the city’s building division, SDG&E scheduled to pull and reset the meter, then the actual swap and Span commissioning on install day. You can verify any electrician’s license through the CSLB license lookup before signing anything.
If you’re weighing Span against Lumin, the other smart panel option that doesn’t require a full swap, see our Span vs. Lumin comparison and our Lumin Smart Panel cost guide for the lower-cost alternative.
Frequently asked questions
How much does a Span Smart Panel cost installed in San Diego?
Installed cost runs $6,500 to $10,000, with hardware around $3,500-$4,000 and install labor plus permit making up the rest. If your service or meter also needs upgrading to support solar and battery, add $2,000-$4,000 on top.
Is a Span Panel a full panel replacement?
Yes. Span replaces your existing main panel entirely, it isn’t an add-on device installed alongside your current breakers. That’s the biggest difference between Span and Lumin, which installs alongside your existing panel.
Do I need solar or a battery to justify a Span Panel?
Not strictly, but that’s where the value is clearest. Without solar and battery, you’re paying a premium mainly for app-based monitoring and remote circuit control, which is nice but not essential. With a battery, the per-circuit backup prioritization can meaningfully extend runtime during an outage.
How long does a Span Panel installation take?
Most installs take a full day, including the SDG&E meter pull and reset, which typically means 4 to 8 hours without power. Commissioning the app and setting up circuit labels and priorities happens after power is restored.
Does a Span Panel need a permit in San Diego?
Yes, every panel replacement requires a city permit and inspection, no exceptions. A licensed electrician pulls the permit, coordinates with SDG&E on the meter work, and schedules the inspection.
When to call us
A full panel replacement touches your entire home’s electrical service, and Span’s commissioning adds another layer most general electricians haven’t done dozens of times. We handle the load calculation, the SDG&E coordination, and the Span setup as one project so you’re not stuck between three different contractors. Our smart home wiring service covers the app and automation side once the panel is in. Call us at (858) 988-5580 for a same-day estimate.
