Frequently Asked Questions
Yes, particularly for non-straightforward projects. Save A Lot Solar's 14 years means they've handled solar installations through multiple technology transitions, incentive program changes, and thousands more roof configurations. This shows up in their customer feedback about successfully navigating strict permitting and installing on century-old homes—experience that matters when complications arise. Sunvault's 6 years is adequate for standard installations but provides less depth for problem-solving unexpected issues.
The specific mention of workmanship quality requiring follow-up evaluation is a legitimate concern for a permanent installation like solar. Unlike cosmetic issues, solar workmanship affects system performance, roof integrity, and warranty validity for 25+ years. If you choose Sunvault based on pricing, build in extra scrutiny during installation milestones and consider having an independent inspector review the work before final sign-off.
Save A Lot Solar has specific customer feedback mentioning battery backup systems and Enphase battery installations, plus experience with system expansions. Their detailed approach to system sizing suggests they'll properly integrate storage with your existing or planned solar capacity. Sunvault's review data doesn't mention battery projects specifically, so you'd need to ask directly about their experience with the battery system you're considering.
Customer feedback for Save A Lot Solar specifically notes their quotes came in below competitors while using quality equipment, suggesting their pricing is competitive despite greater experience. The consistent feedback about adhering to quoted prices means you're less likely to face change orders or additional costs. Get detailed quotes from both, but evaluate the total value including execution consistency, not just the initial number.

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.
