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.
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.
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.
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.
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.
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.
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.
“We were having serious problems with our Tesla, solar system, and Carlos came out to evaluate the problems. He was right on target with what the problems were, and he called his boss just to confirm which I appreciated the second opinion. They will be installing the solar system correctly and I’m so relieved. Carlos was wonderful. He is so personable and so intelligent, and I admire him. Can’t wait to get this whole system fixed”
“We've had an exceptional experience with Sunrise Electrical Contracting. In the middle of winter with a 5 week old baby - we found ourselves without power once again in the Santa cruz Mountains. We had already purchased a solar system but hadn't set it up. My husband called Sunrise Electrical Contracting and connected with Branden who came on an emergency call on short notice. He was able to set up our solar system in a few hours and took a lot of time to explain things to my husband who asks a lot of questions and give him advice on the system. Branden was professional and friendly, as well as extremely knowledgeable and friendly while he met at our home. He got us out of a bind and now we can keep our house warm. The rate was great and out of the companies we called, they were the most responsive. We definitely trust this company with our electrical needs moving forward and recommend them to anyone who needs work.”
Pulled from what we actually hear on quotes and on-site. If yours isn't here, ask us — we'll answer in plain English.
We'd rather you get the right outcome than the Sunrise outcome. Some of this points away from us on purpose.
Look for a CSLB-licensed C-10 contractor who is a certified installer for the system you're considering. 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.

FranklinWH batteriesA 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.
