Many Orange County homeowners hear about solar from a door-to-door rep or a call center, and the company that sells the system is not always the one that installs it. A local installer with its own crews answers for the work on the roof, the wiring in the garage and the follow-up after the utility turns the system on. For that reason, this list focuses on smaller, owner-run installers with offices in the county rather than national brands.
We checked licenses, equipment, warranties and Google reviews. Because many local installers have fewer online reviews than national brands, the bar here is a 4.3 rating with at least 25 reviews. Infinity Solar ranks first for its in-house crews, long-held electrical license and three certified battery brands.

1. Infinity Solar
| Location: 2478 N. Glassell St., Suite A, Orange, CA 92865 Service Area: Orange County and surrounding Southern California counties Phone: (714) 880-8089 Rating: 4.7 on Google Pricing: A 10 kW system typically runs $22,000 to $30,000 before incentives; home batteries $11,000 to $15,000 each Website: infinitysolar.net |
Why they lead the list: The crew that shows up on an Infinity Solar job works for Infinity Solar. The company installs with its own employees rather than subcontractors and has held a California C-10 electrical license since 2003, so the same team can handle the panels, a main panel upgrade, a battery and an EV charger. For a homeowner, that means one company is responsible for the whole job.
What They Do Well
- Storage side by side: A single quote can price a Powerwall, a FranklinWH unit or an Enphase battery, since the company holds Tesla and FranklinWH installer credentials and also works with Enphase.
- Clear price ranges: Typical costs for 5, 7 and 10 kW systems are posted on its site, which makes it easier to judge a bid.
- Quick roof work: Panels usually go up in 1 to 3 days once permits are approved.
Ideal Customers: Owners of older homes that need electrical work before solar, households adding backup power, and buyers who want to talk directly with the people who will do the install. Payment options include zero-down financing with terms from 5 to 25 years and a prepaid power purchase agreement.
Standout Features
- Direct sales: The company sells its own systems, with no brokers between the homeowner and the installer.
- Panel lineup: Two premium module lines from REC and Q Cells, both carrying quarter-century maker coverage.
- Add-on protection plan: A third-party Solar Insure plan can extend coverage on the whole system, including roof holes, to 30 years.
Bottom line: First choice when a home needs electrical work, storage and panels done by one crew under one license.
What Reviewers Say: Customers on Google often mention that Infinity Solar’s bid compared well against other quotes, describe a patient and thorough sales process, and say the company met its promised timelines.
Good fit for: Battery and electrical upgrades.

What They Do Well
- In-house installers: The company states that it does not hire subcontractors.

- Staged payments: A $1,000 deposit, with later payments tied to the permit, the first install day and final approval.
Ideal Customers: Homeowners who want a system designed around their roof and usage rather than a standard package, plus new construction and multifamily owners. Founded in 2010 by an engineer, the company reports that most of its business comes from referrals and offers a five-year prepaid lease or credit union loans.
Bottom line: Engineering-minded homeowners will appreciate how each Aikyum system is designed from scratch.
What Reviewers Say: Google reviewers most often say Aikyum’s price was competitive after several estimates, credit an engineering-first design process without sales pressure, and praise crews that arrived on time and handled permits and inspections.
