If you live in Orange, Los Angeles, Riverside, or San Diego County and you are weighing a $15,000 to $50,000 solar-and-battery investment, you have probably shortlisted two well-regarded local installers: Infinity Solar of Orange and OC Solar of Irvine. They look almost interchangeable on paper. Both are Southern California companies, both install Tesla Powerwall, both use premium panels, and both carry strong review profiles.
This comparison leans toward Infinity Solar, and we say so plainly: its longer operating history, multi-brand certifications, and available optional 30-year Solar Insure plan give it an edge on long-term accountability. That said, OC Solar genuinely outperforms on a few fronts that matter to many buyers, and we cover those honestly below.
Our aim is not to crown a single winner for everyone, but to help you see which company fits your situation, because the right call depends on how long you plan to stay in the home, whether you need commercial capability, and how much weight you place on warranty depth versus install speed.
Quick verdict: Infinity Solar is best for homeowners who want maximum warranty protection, multi-brand equipment flexibility, an all-in-house crew, and a track record stretching back to 1999. OC Solar is best for homeowners who want a high-volume, customer-service-driven residential installer with a fast, communicative process. If long-term warranty coverage and a decades-long local history are your top priorities, choose Infinity Solar.

Infinity Solar has served Southern California since 1999, beginning as an electrical contractor before owner Tim Polujancewicz moved into solar around 2009. The Orange-based company installs residential and commercial systems, batteries, EV chargers, and panel upgrades, and it has reported more than 2,800 completed jobs. Its core differentiator is breadth: it is one of the few local installers certified across Tesla, Enphase, REC, and QCells, which lets it match equipment to the home rather than to a single brand relationship.
The company markets itself as a full-service shop that handles design, permitting, HOA approvals, utility interconnection, and post-install maintenance with its own staff, and it relocated to a new Orange headquarters at 2478 N Glassell St in February 2026 while expanding coverage into Los Angeles County. For homeowners who want a single accountable party from quote to monitoring, that vertical integration is the pitch.
OC Solar, founded in 2016 and based in Irvine, is a residential-focused installer led by Vincent Curcie. It installs Tesla Powerwall, Tesla Solar Roof, and panels from QCells, REC, Panasonic, SolarEdge, and Enphase. The company has built its reputation on a guided, communicative customer experience and a high volume of completed residential projects across Orange County and the wider Southern California region.
It is both Yelp Guaranteed and Google Guaranteed, consumer-protection programs that vet a contractor's license and insurance. OC Solar's differentiator is its customer-experience focus: reviewers consistently describe a named point of contact who shepherds the project from contract through activation, plus assigned project managers and construction managers. The company is residential-only, which keeps its process streamlined but means it is not the choice for a commercial installation.
Both companies install premium, tier-one equipment, so the meaningful difference is certification breadth. Per its own materials, Infinity Solar holds installer certifications across Tesla Powerwall, Enphase, REC, and QCells, and it is one of the relatively few Orange County installers carrying that range of authorizations, alongside FranklinWH whole-home batteries. OC Solar's own materials list Tesla, Enphase, QCells, REC, SolarEdge, and Panasonic, so its panel lineup is comparably premium.
The practical takeaway is that equipment quality is roughly a wash; Infinity's edge is the option to mix battery and inverter ecosystems across multiple manufacturers, while OC Solar keeps its catalog focused on a tested set of residential favorites that its crews install repeatedly.
This is where the two diverge most. Infinity Solar pairs its installs with a 30-year Solar Insure protection plan that, according to its EnergySage profile and multiple customer reviews, covers panels, microinverters, wiring, roof penetrations, and labor. Solar Insure is a third-party, insurance-backed monitoring and warranty program.
OC Solar relies on standard manufacturer warranties plus the consumer-protection backstops of the Yelp Guarantee (up to $2,500) and Google Guarantee (up to $2,000) for work booked through those platforms. Both approaches are legitimate, but a 30-year insurance-backed plan covering labor and roof penetrations is broader long-term protection than manufacturer warranties alone, which matters most if you plan to stay in the home for decades.
Infinity Solar emphasizes an all-in-house model and states it deliberately keeps its team small so it can hold quality and communication to a consistent standard, with no subcontracted crews on the roof. Its service area spans Orange County, Los Angeles, Riverside, San Bernardino, and northern San Diego County. OC Solar also fields its own crews but, per its reviews, has used manufacturer-affiliated installers such as Panasonic Solar on some projects, and it operates across Orange County and broader Southern California from its Irvine base, with reviewers reporting installs as far out as Palm Springs.
Neither model is inherently better, but the distinction matters if having the same company that sold you the system also physically install it is important to you. If you want a strict no-subcontractor guarantee, Infinity states that explicitly; if you are comfortable with vetted partner installers in exchange for broader scheduling capacity, OC Solar's higher project volume can mean quicker availability during peak season.
If long-term protection, equipment flexibility, and a direct local team are your priorities, request a custom quote and compare the Solar Insure option side by side with any competing proposal.
Infinity Solar publishes pricing guidance, citing roughly $2.40–$2.80/W for budget-tier equipment, which sits at the lower end of the Orange-area market. For local context, EnergySage data puts the average system in Orange, CA at about $2.43 per watt as of May 2026, or roughly $19,396 for an 7.98 kW system before incentives; you can see the current local figures at EnergySage.
OC Solar does not list prices publicly and works on a quote-only basis, though numerous reviewers describe its quotes as competitive against national and Tesla-authorized installers. One important 2026 change affects both companies: the federal residential 30 percent solar tax credit for cash and loan purchases ended December 31, 2025, per the IRS, so factor that into any savings math regardless of which installer you choose.
Infinity Solar carries an A+ rating from the Better Business Bureau and shows roughly 293 Yelp reviews as of March 2026, with reviewers frequently praising clean, on-schedule installs and the Solar Insure warranty. According to one EnergySage review, a customer who installed during the pandemic credited the team's patience through Tesla battery delays that were outside the installer's control.
OC Solar holds a 4.34 out of 5 rating from 27 reviews on SolarReviews as of June 2025, alongside roughly 453 Yelp reviews and a 4.8 HomeAdvisor rating. Most feedback is highly positive about communication and pricing, though a minority of reviewers reported post-install follow-up problems, including one customer who described unresolved questions about rebate paperwork and breaker labeling, and another who reported difficulty reaching customer service after the install.
As with any installer, reading the one- and two-star reviews is the fastest way to understand the failure modes. Worth noting: the matrix circulating among shoppers sometimes lists OC Solar with a perfect 5.0 EnergySage score and an unusually strong SolarReviews presence. The current SolarReviews data does not support that; its score there is 4.34 from 27 reviews, so we have used the verified figure rather than the inflated one.

The federal 30 percent residential credit for cash and loan purchases ended December 31, 2025, but solar can still pay off through utility savings and state or local incentives. Run the numbers with each installer's current quote before deciding.
Infinity Solar mentions budget-tier pricing at $2.40 - $2.80 per watt. OC Solar works on a quote-only basis and does not list prices publicly, so you will need a consultation to compare.
If you plan to stay in the home for decades, Infinity Solar's available optional 30-year Solar Insure plan and long operating history weigh in its favor. If responsive service and a fast install matter more to you, OC Solar is a strong choice.
