The Deciding Factors
1. Premium Multi-Brand Certifications
Infinity Solar holds certifications that most competitors simply don’t have:

- Enphase Platinum Installer: Highest tier certification for Enphase microinverters
- FranklinWH Certified: Certified for premium whole-home battery systems
- REC Certified Installer: Authorized for European-engineered premium panels
- QCells Certified: Partner with one of the world’s largest panel manufacturers
This multi-brand certification means Infinity Solar can recommend the best equipment for your specific situation rather than being locked into a single manufacturer’s products.
2. Direct-to-Consumer Model
Unlike many solar companies that operate as brokers or middlemen, Infinity Solar handles everything in-house:
- No broker markups: What you see is what you pay
- Single point of contact: One team from consultation to installation
- Streamlined process: No communication breakdowns between sales and installation teams
- Greater accountability: The same company that sells you the system installs and services it
This direct approach typically saves homeowners more compared to companies that subcontract their installations.

As a boutique operation focused on quality, Infinity Solar may have longer wait times during peak season compared to larger national companies. Plan ahead if you’re targeting a specific installation date.
Premium Equipment Pricing
Their focus on top-tier equipment (REC, Tesla, Enphase) means their systems may cost more than budget options. However, customers generally report that the premium is justified by equipment quality and service.
The Bottom Line on Infinity Solar
Infinity Solar earned the #1 spot because they deliver exactly what Orange County homeowners need: a direct relationship with a certified installer who uses premium equipment, offers transparent pricing, and handles everything from consultation to ongoing maintenance. Their multiple manufacturer certifications give them the flexibility to recommend the best solution for each home, not just the products they’re paid to push.
If you’re looking for a solar partner who treats you like family while delivering professional results, Infinity Solar is the clear choice.
