Consider Suntegrity Solar if...
- ✓ Your home was built before 2000 or has complex roof architecture where hidden structural issues, outdated electrical systems, or unusual configurations may require experienced problem-solving during installation
- ✓ You're rebuilding after a fire or coordinating solar installation with other major construction work, where Suntegrity's documented experience working with architects and contractors becomes directly relevant
- ✓ You're expanding an existing older solar system or working with legacy equipment, where their 49-year history means they've likely encountered similar systems and know how to integrate new technology with older installations
- ✓ You value the institutional knowledge that comes from nearly five decades in business, including relationships with local building departments and utility companies built over generations
Consider Michael & Sun Solar if...
- ✓ Your home is newer (built after 2000) with straightforward roof access and standard electrical configuration, where a 14-year track record provides sufficient experience for smooth execution
- ✓ You prioritize working with a somewhat smaller, established operation where 14 years still represents substantial stability and customer satisfaction without the possible premium of a veteran contractor
- ✓ Your project is a standard rooftop installation with battery backup using current technology like Enphase systems, which falls squarely within Michael & Sun Solar's demonstrated expertise
- ✓ You appreciate that their 14-year timeframe means they've worked exclusively in the modern solar era with current technologies and haven't had to transition through older, obsolete systems
Questions to Ask Before Hiring
- → For Suntegrity Solar: Given your 49 years of experience, can you share examples of unusual problems you've encountered on projects similar to mine and how that experience would benefit my installation?
- → For Michael & Sun Solar: What's the most complex installation your team has completed, and how does my project compare in terms of difficulty?
- → Ask both companies how they handle unexpected issues discovered during installation, such as roof repairs needed or electrical panel upgrades, and whether those costs are clearly defined upfront or handled as change orders
The Bottom Line
Both companies are legitimate, well-insured contractors who deliver quality solar installations with strong customer communication. Choose Suntegrity Solar if your project involves any complexity: homes built before 2000, fire rebuilds, difficult roof configurations, system expansions, or situations where you want the deepest possible experience handling complications. Their 49 years provides substantially more institutional knowledge for problem-solving. Choose Michael & Sun Solar if your project is straightforward—newer home, standard rooftop installation, uncomplicated electrical—where their 14 years is entirely sufficient and you may benefit from working with a somewhat smaller established operation. Get quotes from both regardless, but weight Suntegrity's experience more heavily as project complexity increases.

Frequently Asked Questions
For a standard installation on a newer home with uncomplicated roof access and modern electrical, probably not. Both companies demonstrate professionalism and quality work in customer feedback. The experience advantage matters most when complications arise—older homes, fire rebuilds, difficult roof configurations, or integration with existing systems. If your project is straightforward, Michael & Sun Solar's 14 years is more than adequate.
You should request quotes from both to compare directly. Customer feedback suggests both price competitively, but that doesn't mean identically. Suntegrity's longer tenure might command slightly higher pricing for complex projects where their experience adds clear value, while straightforward installations may be priced similarly. The key is comparing not just the bottom line but what's included in each proposal and how each company plans to handle potential complications.
Suntegrity Solar specifically mentions experience with fire rebuild installations and coordinating with architects on residential projects, which directly addresses your situation. Fire rebuilds involve timing coordination with other trades, working with insurance requirements, and often dealing with upgraded building codes. Their 49-year history means they've likely handled dozens of these complex scenarios. While Michael & Sun Solar may also be capable, Suntegrity has documented experience with exactly this type of project.
High owner involvement typically means the business owner stays closely connected to projects rather than delegating everything to crews. This often translates to better quality control, more consistent communication, and someone with decision-making authority directly accessible when questions arise. For solar installations that require permits, utility coordination, and system design decisions, having owner-level attention helps ensure nothing falls through the cracks at critical stages.

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.
