Frequently Asked Questions
Yes, it matters for complex situations. Suntegrity's 49 years means they've seen virtually every complication that can arise with roof conditions, utility requirements, and permitting issues. For straightforward installations on newer homes, Westcoast's 15 years provides solid expertise. But if your roof is older, your project involves fire rebuild coordination, or you anticipate utility complications, the deeper institutional knowledge becomes valuable insurance against costly delays.
Westcoast shows clearer strength in maintenance and repair work, with specific customer praise for inverter replacements described as fast, efficient, and affordable. While Suntegrity does system expansions for existing customers, the review data suggests Westcoast has developed particular expertise in servicing existing systems rather than just installing new ones.
Some customers mentioned challenges when seeking smaller projects or specialized work like generator installations, suggesting Westcoast may be selective about project types they accept. If you're planning anything outside standard solar installation or inverter work, ask directly during your consultation whether your project fits their current service model to avoid wasted time.
Both avoid aggressive sales tactics, but Suntegrity customers emphasize thorough consultation with detailed communication maintained throughout the entire installation process, while Westcoast customers highlight educational content like videos and explanations of long-term benefits. Suntegrity's approach appears more project-coordination focused, while Westcoast leans toward technology education.

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.
