Tesla Powerwall installation in Santa Cruz County

We're certified Tesla installers. Powerwall is the tightest all-in-one option if you're starting fresh — and the same C-10 crew handles the panel and interconnection work it depends on.

02What this is

Powerwall is Tesla's home battery, and its defining trait is how much it does in one box. Newer Powerwall generations include the solar inverter, so a fresh solar-plus-battery install needs fewer separate pieces of equipment on the wall and fewer conversion steps between your panels and your house.

Powerwall 3 can also work alongside existing solar, keeping the solar inverter you already have. Whether that arrangement suits your home depends on the inverter, system size and backup design. We compare keeping your equipment with changing it before recommending a system.

New to batteries generally? Start with home battery backup — it covers what a battery does in an outage, how long it really lasts, and whether you need solar. This page assumes you've got that and want to know about Powerwall specifically.

04What's included

Exactly what we handle — and the two things you handle.

Sunrise provides

  • Powerwall unit or units, plus the Tesla Gateway that handles grid disconnect and backup switching
  • All interconnection between the Powerwall, your main panel, and the utility service
  • Critical-loads subpanel where that's the better answer, including moving the circuits that matter
  • Any panel or service work the interconnection turns up, quoted before we start
  • Integration with new or existing solar, including an honest assessment of whether your existing inverter should stay
  • Mounting, conduit, disconnects and labelling to current California Electrical Code
  • Building permit, inspection, PG&E interconnection application and permission-to-operate
  • Commissioning with a real outage test, Tesla app set up on your phone, warranty registered
Warranty: 20-year workmanship, transferable. The manufacturer's own equipment warranty runs separately and we register it for you. · Permits: pulled + inspection coordinated by us, built into the quote · Cleanup: packaging and offcuts hauled away, penetrations sealed, conduit runs made tidy rather than merely functional. Drywall and paint repair where equipment was mounted is out of scope — we say so at quote rather than after.

You provide

  • Access to the panel, the meter, and the intended equipment location on the work day
  • A clear list of what has to keep running — this is what sizing is built from
  • Wi-Fi at the equipment location, so monitoring works from day one
  • HOA or architectural approval where applicable
05How it works

Start to finish, with real times.

11–2 hrs on-site

Free home inspection and sizing

A tech looks at your panel, your service, and where the equipment could physically go, then works through what you actually want running when the power is out. That list is the whole design — it decides how many units you need and whether you're backing up the whole house or a critical-loads subpanel. You get a written report and a real number.

22–6 weeks, mostly waiting on others

Permit and utility interconnection

We pull the permit from your city or county building department and file the interconnection application with PG&E. The paperwork is usually the long pole, not the labour — timelines vary across the county, and we tell you the realistic date rather than the optimistic one.

31–2 days on-site

Install day

Powerwall and Gateway mounted and interconnected, any subpanel work done, conduit run and labelled. Your power is off for part of the day while we work at the service — we tell you which part in advance.

4Half a day, plus inspector and utility scheduling

Inspection, commissioning, and handover

Inspection by the building department, then permission to operate from PG&E, then commissioning. We run a real outage test — cut the feed, watch it transfer, confirm it carries what you asked for — set up your monitoring app, register the equipment warranty, and walk you through what happens automatically and what doesn't.

06Pricing transparency

Every quote is free. The range depends too much on your home to fake it.

We give you a real number at the free inspection rather than a range on a web page. Battery projects vary more than most electrical work — what you want backed up, where the equipment can physically go, how far it is from your panel, and whether your service can take it as-is are each large enough to move the total on their own. One thing to get straight before you budget: there is no federal tax credit on home battery storage for 2026 installs. Section 25D — the 30% residential credit that covered owned solar and standalone storage — terminated on 31 December 2025. If a quote or an article you're reading still assumes it, that assumption is out of date, and we'd rather you hear it from us than at tax time.

Financing · GoGreen Home
Financing is available on battery projects when they qualify — GoGreen Home is tied to qualifying energy-efficiency work, and battery storage paired with solar or electrification generally fits. We walk through your specific pathway at quote rather than putting an invented monthly figure on a web page.

What it costs
Quotes are free. The variance on this work is too wide for an honest range — book a free inspection and we’ll give you a real number for your specific home, in writing.
What moves the number
How much of the house you want backed up — a critical-loads subpanel and whole-home backup are different jobs · How many battery units, which is a function of what you run and for how long · Distance and route from the equipment location to your main panel · Whether your existing panel and service can take the interconnection as-is, or need work first · Whether you have existing solar, and what inverter it uses · Mounting location — garage wall, exterior wall, or a location needing weather and temperature consideration · Permit and utility interconnection timelines, which vary by jurisdiction across the county · Whether an existing solar inverter is being retained or retired — this is the question that most often changes a Powerwall quote
No hidden fees. Every quote is free and detailed.
09Frequently asked questions

6 questions. Real answers.

Pulled from what we actually hear on quotes and on-site. If yours isn't here, ask us — we'll answer in plain English.

I already have solar. Does Powerwall still make sense?
It can. Powerwall 3 supports existing solar through an AC-coupled design, subject to Tesla's system-sizing and installation requirements. We check your inverter, solar capacity and backup loads, then compare Powerwall with alternatives such as FranklinWH. Existing solar alone doesn't decide which battery is the better fit.
Can I back up my whole house?
Often yes, with enough capacity — Powerwall units stack, and the Gateway can be configured for whole-home backup. Whether you should is a different question. Whole-home backup has to cope with anyone switching anything on during an outage; a critical-loads subpanel is frequently better value and removes the risk of the dryer flattening your reserve. We size both ways at the inspection and show you the difference.
What does it actually do when the power goes out?
The backup system isolates your home from the grid and Powerwall supplies the circuits included in your backup design. Transfer is automatic, but a brief interruption can occur. During a longer outage, reducing heavy appliance use helps preserve the remaining charge. Available backup depends on stored energy, solar production and the loads running; check the Tesla app and follow the system's outage guidance.
How many Powerwalls do I need?
That comes from what you want running and for how long, not from your house size. One unit backing a well-chosen set of circuits goes a long way; whole-home backup on a large house with air conditioning is a different calculation. We work it out from your actual load list at the inspection rather than from a chart.
Is there a federal tax credit?
Not for 2026 installs. Section 25D — the 30% residential credit covering owned solar and battery storage — terminated on 31 December 2025. Plenty of material online still assumes it applies. It doesn't.
Do you install Powerwalls you didn't sell?
We'll service and troubleshoot existing installs, and we'll take on work another installer left unfinished — that happens more than you'd think. Most contractors won't touch someone else's battery install. We will, and we'll tell you honestly what we find.
10Even if Sunrise isn't the answer

Here’s the honest path — wherever it leads.

We'd rather you get the right outcome than the Sunrise outcome. Some of this points away from us on purpose.

Outside Santa Cruz County?

Look for a CSLB-licensed C-10 contractor who is a certified installer for the system you're considering — certification is what governs warranty registration and parts access. Verify the licence at cslb.ca.gov, and check the quote includes the permit, the utility interconnection, and any panel work rather than adding them later.

Have existing solar?

Keeping your existing solar may be possible with Powerwall 3. We compare the equipment you have, the circuits you want backed up and each system's compatibility requirements. FranklinWH is another option to consider.

FranklinWH batteries

Not sure a battery is the answer?

A free whole-home inspection tells you what your service can actually support and what backing up your house would really involve. You keep the written report either way, and about a third of these end with no work scheduled.
