Consider Citadel Roofing And Solar if...
- ✓ You want documented reassurance through customer reviews that highlight prompt service, effective troubleshooting, and clear communication throughout the project
- ✓ Your project involves both roofing and solar work, or you need battery backup systems like Powerwall integrated with your installation
- ✓ You need a contractor with workers compensation insurance to eliminate potential liability if someone gets injured during your project
- ✓ Your existing solar system has ongoing issues and you want a company with proven diagnostic expertise across multiple equipment brands
Consider Robert's Solar if...
- ✓ You're located in Dixon and value working with a local contractor in your immediate community
- ✓ You have a straightforward solar panel installation without roofing complications or battery integration
- ✓ You're comfortable verifying current insurance status directly and confirming your homeowner's policy provides adequate coverage for contractor injuries
- ✓ You can obtain and check recent references since public review history is limited
Questions to Ask Before Hiring
- → Ask Robert's Solar directly about their current workers compensation status and request documentation, then verify with your homeowner's insurance whether you're covered if a contractor without workers comp is injured on your property
- → Request from Robert's Solar at least three recent references from projects completed in the past year, and actually call them to ask about communication, timeline adherence, and problem resolution
- → Ask both companies how they handle warranty claims if equipment fails, especially if you're considering brands or inverters you're unfamiliar with
- → If your project involves both roofing and solar, ask for specific examples of similar integrated projects they've completed recently
The Bottom Line
Citadel Roofing And Solar is the safer choice for most homeowners this week. Their workers compensation coverage protects you from liability, their documented customer reviews confirm responsive service and technical competence, and their broader service offerings handle roofing integration and battery systems if needed. Robert's Solar may be viable if you're in Dixon, obtain strong recent references, and can verify adequate insurance protection, but you'll be taking on additional verification work and potential liability risk. Unless you have compelling reasons for the extra diligence, choose Citadel for straightforward protection and proven performance.

Frequently Asked Questions
It matters significantly because solar installation involves working on your roof, which carries inherent fall risks. If a worker without workers comp coverage is injured on your property, they may sue you directly or file a claim against your homeowner's insurance. Workers comp protects you from this liability by covering the worker's medical expenses and lost wages through the contractor's policy instead of yours.
Not necessarily—it simply means you have less verifiable information about recent customer experiences. Some established contractors don't actively collect online reviews. However, it does mean you'll need to do more due diligence yourself by requesting and checking recent references, rather than relying on documented feedback patterns like you can with Citadel.
If you're in Dixon and value immediate local proximity, Robert's Solar offers that. Their 32 years of licensing demonstrates long-term business survival and likely competence with solar technology. However, you'll need to address the workers comp gap either by confirming they've added coverage or ensuring your own insurance adequately protects you, and you should definitely check references given the limited review history.
The two-year difference in licensing (34 vs 32 years) is negligible—both are clearly veteran contractors who've worked through multiple solar technology generations. The meaningful differences lie elsewhere: insurance coverage, documented customer feedback, and service breadth rather than the minor gap in years licensed.

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.
