What Customers Say
Quattro Solar
Customers consistently emphasize owner David Quattro's personal integrity, direct involvement, and sustained attention to both work quality and client relationships.

Consider Quattro Solar if...
- ✓ You prioritize direct access to the owner and consistent point-of-contact throughout your project and during the 25-year lifespan of your system
- ✓ Your property presents potential complications (older roof, complex electrical, shading issues) where personal oversight and adaptive problem-solving matter more than standardized processes
- ✓ You value a contractor who will likely remember your installation when you call years later for service or system expansion
- ✓ You're willing to potentially sacrifice some process efficiency for personalized attention and relationship continuity
Consider Solarcraft if...
- ✓ You want maximum industry experience and a contractor who has successfully navigated nearly four decades of solar technology changes and regulatory shifts
- ✓ Your project is straightforward (newer roof, standard electrical, good sun exposure) where professional installation crews and efficient processes deliver excellent results
- ✓ You prioritize competitive pricing and appreciate the employee-owned business model over owner-operated structure
- ✓ You're comfortable being proactive about scheduling service needs and following up on warranty issues if equipment problems arise
Questions to Ask Before Hiring
- → Ask Solarcraft specifically how warranty service requests are prioritized and what their typical response time is for equipment failures—request references from customers who needed post-installation service, not just installation references
- → Ask Quattro Solar about their installation crew size and project timeline expectations, since smaller operations may have longer scheduling lead times
- → Ask both companies who will be your point of contact if issues arise 2-3 years after installation and whether that person is typically available or requires multiple follow-ups
- → Ask about their experience with your specific equipment brands and whether they stock common replacement parts locally or need to order them
The Bottom Line
Solarcraft offers substantially more industry experience and efficient installation processes at competitive pricing, making them the stronger choice for straightforward residential solar projects where you're comfortable being proactive about service needs. However, their customer-reported post-installation service challenges are a legitimate concern for a 25-year investment. Quattro Solar provides notably more personal attention from ownership and sustained relationship continuity, making them better suited for complex installations or homeowners who prioritize responsive long-term support over maximum industry longevity. Ask Solarcraft specifically about their warranty service response times and request post-installation references. Ask Quattro Solar about project timelines and crew capacity. For most straightforward installations, Solarcraft's 39-year track record and professional execution outweigh service concerns, but factor that maintenance accessibility into your decision.

Frequently Asked Questions
Yes, it matters practically. Solarcraft has been operating longer than most solar warranties last, meaning they have institutional knowledge of older systems and have survived multiple industry shakeouts that eliminated competitors. Quattro Solar's 15 years is still substantial and means they've handled thousands of installations through significant technology changes. The bigger practical difference appears to be post-installation responsiveness rather than raw years of experience.
Larger, more established companies often develop separate installation and service departments, which can create communication gaps. Solarcraft's strength in efficient installation processes may come at the expense of sustained customer relationships. This is a common tradeoff with successful companies that scale up—excellent execution during the project phase, but less personalized attention when you need something months later. Ask them directly about this pattern and how they're addressing it.
Owner involvement typically decreases as companies grow, but Quattro Solar's 15-year history at their current operational scale suggests David Quattro has chosen to maintain a size where personal involvement remains feasible. Ask him directly about recent growth plans and how many projects he's personally overseeing. Customer reviews consistently mention his accessibility, which indicates this isn't just a sales tactic but an operational reality.
Both matter for solar, which requires 25+ year performance. Solarcraft clearly excels at installation execution with professional crews and thorough education. Quattro Solar's customer feedback emphasizes relationship continuity and owner integrity. If your system is straightforward and you're comfortable being proactive about service needs, Solarcraft's installation expertise is valuable. If you anticipate needing ongoing attention or have a complex property, Quattro Solar's sustained involvement may prove more valuable over decades.

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.
