Consider Corda Solar if...

- ✓ You're located in Danville and prefer working with a contractor based directly in your community for easier access and local accountability

Questions to Ask Before Hiring
- → If considering Corda Solar for a complex roof, ask for references from projects with similar roofing materials to verify their specialized installation experience
- → If considering Got Watts for solar-only work, ask what percentage of their current projects involve solar to understand how central it remains to their business focus
- → Ask both companies about their typical timeline from contract signing through final inspection and utility permission to operate, since permitting coordination is critical to project completion
The Bottom Line
If you need only solar installation and value specialized expertise with competitive pricing, Corda Solar's nine years of dedicated focus serves that purpose well, particularly for complicated roof configurations. If you want comprehensive electrical capabilities, detailed proposal options, and regular project communication, Got Watts' twelve years as an established electrical contractor provides broader expertise and a more consultative approach. The three-year experience gap and Got Watts' detailed communication style give them an edge for homeowners who value extensive updates and may need related electrical work. Choose Corda Solar if you're confident in your project scope and prioritize solar-specific technical expertise at competitive rates.

Frequently Asked Questions
It depends on your property's electrical infrastructure. If your main panel needs upgrading to accommodate solar or you'll want an EV charger soon, Got Watts handles both without coordinating separate contractors. If your electrical system is already adequate and you're focused purely on solar, Corda Solar's specialized focus may offer more competitive pricing for straightforward installations.
The gap is meaningful but not decisive. Got Watts' twelve years provides more exposure to California's regulatory changes and installation standard evolution, which helps with permitting and utility coordination. Corda Solar's nine years still represents substantial experience, particularly for technically complex installations that customer feedback specifically highlights.
Both companies handle battery storage and system expansions, with customer feedback showing Got Watts specifically has repeat customers returning for additions over time. Their broader electrical expertise may help if expansions require panel upgrades. Corda Solar's exclusive solar focus means system additions remain their core business rather than one service among many.
Customer feedback shows Got Watts emphasizes detailed proposals with multiple design options and transparent pricing discussions without pressure, suggesting a consultative sales process. Corda Solar receives praise for competitive pricing and technical expertise but less specific mention of the proposal process, indicating they may move more directly to installation once you've decided to proceed.

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.
