Five Orange County companies that install Tesla Powerwall home batteries, compared on Tesla credentials, backup design, battery pricing, warranty terms and customer feedback.
A Tesla Powerwall stores 13.5 kWh of power for evenings and outages, and the newest model, Powerwall 3, has a solar inverter built in. Under Southern California Edison’s net billing rules, power saved in a battery for evening use is usually worth more than power exported at midday, which is why so many Orange County solar quotes now include one. Tesla trains and certifies outside companies to install Powerwall, and the installer’s design choices decide which circuits stay on when the grid goes down.
This guide compares five Orange County companies that install Powerwal. Infinity Solar ranks first for its Tesla installer status, its own electrical crews and published battery prices with clear backup estimates.

Service Area: Orange County and neighboring Southern California counties Phone: (714) 880-8089 Rating: 4.7 on Google Pricing: Most battery systems $11,000 to $15,000 per battery before incentives Website: infinitysolar.net |
Why they lead the list: A Powerwall install is mostly electrical work: tying the battery into the main panel, choosing backed-up circuits and often upgrading the panel itself. Infinity Solar has held a C-10 electrical contractor license since 2003, sends its own crews rather than subcontractors, and lists Tesla Powerwall installer status on its battery page. It also tells homeowners up front what to expect: about 1 to 3 days of essential-load backup from one unit, or 6 to 12 hours for a whole home.
What They Do Well
- Battery comparisons: Prices Powerwall next to Enphase and FranklinWH batteries, which carry longer 15-year warranties, so buyers can weigh capacity against coverage.
- Retrofits and new systems: Adds Powerwall to existing solar or designs solar and storage together.
- Short install: Battery installation usually takes 1 to 3 days, per its site.
Ideal Customers: Homeowners who need a main panel upgrade before adding storage, families who want backup for medical equipment or a home office, and solar owners adding a battery to an older system. Zero-down financing and a prepaid power purchase agreement are available.
Standout Features
- Stated backup estimates: Published run times for essential and whole-home backup.
- Several storage brands: Also certified for FranklinWH and installs Enphase batteries.
- One point of contact: The salesperson, designer and installer all work for Infinity, so questions after the install go to the same company.
Bottom line: Call Infinity first if your Powerwall project also involves panel or wiring work.
What Reviewers Say: Google reviewers often say Infinity’s quote beat other bids they collected, praise patient explanations from the sales team, and describe projects finished on the promised schedule.
Good fit for: Powerwall with panel upgrades.

Service Area: Southern California Phone: (949) 427-8817 Rating: 4.8 on Google Pricing: Powerwall 3 installed $9,995 to $15,995 Website: ocsolar.com |
What They Do Well

- Scalable systems: Installs up to 4 Powerwall 3 units together, with whole-home or essentials-only backup.

Bottom line: A strong choice for multi-battery and Tesla Solar Roof projects.
What Reviewers Say: Google reviewers most often mention that the company handled permits and utility paperwork, kept them updated, and ran conduit neatly or out of sight.
Good fit for: Multi-battery and Solar Roof jobs.

Good fit for: Battery with a new roof.
How These Companies Were Ranked
Primary factors
- Powerwall installs: Tesla Powerwall offered on the company’s own website.
- Customer feedback: Public positive reviews and ratings
- Local base: An Orange County office and at least two years in business.
Secondary factors
- Tesla credentials: Certified or Premier installer status listed on the company’s site.
- Electrical work: In-house crews and electrical licensing for panel upgrades.
- Price and coverage: Published battery pricing and warranty terms.
- Buyer fit: Each installer had to suit a different kind of battery project.
Final Word
A Powerwall is only as useful as the way it is wired and set up. Infinity Solar ranks first because its own licensed electricians handle the install, and it publishes battery prices and realistic backup estimates before the first visit.
Before signing, ask each installer whether the quote covers whole-home or partial backup, whether your main panel needs an upgrade, which warranty applies to the battery and the labor, and whether you qualify for any remaining state battery rebate.
