Key Differences

The most significant difference is specialization and documented experience. Five Star Solar has spent 20 years focused exclusively on solar installations, handling battery systems, HOA approvals, system expansions, and complex roof configurations. Their customer feedback demonstrates consistent execution across dozens of residential projects with specific praise for installation speed, system design knowledge, and post-installation support. Rex Moore, despite being a legitimate electrical contractor with 13 years of licensing, shows no evidence of residential solar work—their description emphasizes commercial and industrial design/build projects. Without customer reviews, project documentation, or solar-specific experience listed, it's unclear if they actively pursue residential solar installations or have crews trained in roof work, solar permitting, battery integration, and utility interconnection. The seven additional years Five Star Solar has held their license translates to experience navigating changing solar technology, evolving building codes, and utility net metering programs. For a specialized trade like solar installation that combines electrical work, roofing integrity, structural engineering, and utility coordination, proven specialization matters more than general electrical credentials.

Consider Five Star Solar if...

  • You want a contractor whose entire business model centers on residential solar installations, with documented experience in battery systems, HOA approvals, and system expansions that match your project needs.
  • Fast installation matters to you—customers consistently report one to two-day completion times with professional crews experienced in residential roof work.
  • You value being able to review detailed customer feedback about communication, pricing transparency, and long-term support from actual solar customers.
  • You're installing solar as a 25-year investment and want a specialist who will likely still be supporting solar systems when yours needs service or expansion.

Consider Rex Moore if...

  • You have a commercial or industrial electrical project rather than residential solar installation, as this appears to be Rex Moore's actual business focus.
  • You're comfortable being potentially among the first residential solar customers for a contractor without documented solar experience or customer reviews to evaluate.
  • Your project involves complex commercial electrical design/build work where Rex Moore's 13 years of commercial experience would be directly applicable.

Questions to Ask Before Hiring

  • Ask Rex Moore directly: How many residential solar installations have you completed in the past two years, and can you provide references from residential solar customers specifically?
  • Ask Rex Moore: Who on your team handles solar system design, battery integration, and utility interconnection paperwork—and what solar-specific training do your installation crews have?
  • Ask Five Star Solar: What warranty do you provide on installation workmanship, and how do you handle service calls if issues arise years after installation?
  • Ask both: What happens if my roof needs repairs discovered during installation, and do you coordinate that work or do I need to hire separately?

The Bottom Line

For residential solar installation, Five Star Solar is the clear choice. They've spent two decades specializing in exactly the work you need, with extensive customer feedback confirming fast installations, competitive pricing, and long-term support. Rex Moore may be a legitimate electrical contractor, but without any documented solar installation experience or customer reviews, you'd be taking an unnecessary risk on a contractor whose business appears focused on commercial and industrial work. Solar installation is too specialized and too significant an investment to choose a contractor without proven residential solar experience. Contact Five Star Solar for a quote, and if you want additional comparison, seek out other solar specialists—not general electrical contractors without demonstrated solar capabilities.

Frequently Asked Questions

While both hold electrical contractor licenses that legally permit solar work, licensing doesn't indicate actual experience or specialization. Five Star Solar has 20 years of documented solar-specific work with proven residential project execution, while Rex Moore shows no evidence of residential solar experience. Solar installation requires specialized knowledge beyond general electrical work—including roof structural assessment, solar equipment selection, battery system integration, utility interconnection, and navigating solar-specific permitting and rebate programs.

Customer reviews provide the only window into how a contractor actually performs on residential projects similar to yours. Five Star Solar's feedback reveals patterns about installation speed, communication quality, problem-solving ability, and long-term support that licensing status alone cannot show. Without reviews, you cannot verify that Rex Moore actively serves residential customers or how they handle the unique challenges of working on occupied homes with rooftop installations.

Yes, particularly because those extra seven years represent solar industry experience during significant technological changes—from older inverter technology to modern microinverters and battery storage systems. Five Star Solar has navigated multiple generations of solar equipment, changing utility net metering rules, and evolving building codes. This experience matters when diagnosing issues, recommending system sizes, or expanding systems years later.

There's no evidence to support this assumption. Five Star Solar customers specifically mention competitive pricing as a decision factor, and residential solar pricing depends more on supplier relationships, installation efficiency, and overhead costs than company size. Commercial-focused contractors may actually charge premium rates for smaller residential work that doesn't fit their typical project scale. You'd need to get actual quotes to compare, but without documented residential solar experience, pricing is only one consideration among many.

How We Compare Contractors

License Verification

All license data is sourced from official California CSLB records and verified regularly.

Review Analysis

Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.

Detailed Comparison

We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.

Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.

  • Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
  • Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
  • Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
  • Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.

Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
