Consider First Edison if...
- ✓ You're seeking a general contractor for non-solar work and the project doesn't require specialized solar knowledge or permitting expertise
- ✓ You have time to thoroughly vet their solar installation experience through detailed reference checks and can verify their crew's solar-specific training
- ✓ You're willing to accept the risk associated with limited review history in exchange for potentially exploring a less specialized option
Consider Tesla if...
- ✓ You want a contractor with documented solar specialization and 19 years navigating California's solar regulations and utility requirements
- ✓ Your property has installation challenges like steep roof pitch, flat roof, shading issues, or complex layouts that require proven problem-solving experience
- ✓ You value customer-validated expertise in permitting, inspection coordination, and system explanations that affect long-term financial returns
- ✓ You need confidence that your contractor understands inverter systems, net metering enrollment, and federal tax credit documentation requirements
Questions to Ask Before Hiring
- → Ask First Edison for at least three recent solar installation references with similar system sizes and roof types, and verify their crew's solar-specific certifications
- → Ask First Edison how they handle permitting with your local building department and utility interconnection procedures, and who manages the tax credit documentation
- → Ask Tesla about their current installation timeline and crew availability, given their established customer base and potential scheduling demands
The Bottom Line
Tesla is the clear choice for solar installation this week. Their 19 years of licensing, documented solar specialization, and customer-validated expertise in permitting, system design, and complex installations provide the confidence you need for a project involving long-term financial returns and regulatory compliance. First Edison may be a capable general contractor, but the complete absence of verifiable solar experience, project documentation, and customer feedback makes them a risky choice for specialized solar work. Unless First Edison can provide compelling solar references and demonstrate expertise that matches Tesla's documented capabilities, go with the contractor whose solar credentials you can actually verify.

Frequently Asked Questions
Not necessarily. Their license allows solar work, but they provide no documentation of actual solar projects, customer feedback, or specialized expertise. A contractor can hold a valid license for years without performing certain types of work. Before hiring First Edison for solar, you need to independently verify their solar installation history, crew training, and familiarity with current solar permitting requirements.
Yes, because solar projects involve complexities beyond physical installation—permitting coordination, utility interconnection, inverter selection, and financial documentation that affect your long-term returns. Tesla's customer feedback specifically highlights their permitting competence and system explanations, which matter even on simple roofs. Their 19 years means they've navigated regulation changes and can anticipate inspection issues that newer solar contractors might miss.
This could indicate limited online presence, recent entry into solar work, or low project volume. Without reviews, you cannot verify their actual performance, crew quality, or customer satisfaction. Before hiring, ask First Edison directly about their solar project volume, why reviews aren't available, and request at least three verifiable references from recent solar installations you can contact independently.
Only if you can thoroughly verify their solar credentials through detailed reference checks and they demonstrate clear solar expertise during consultation. If they provide compelling references from recent solar projects similar to yours, explain permitting procedures confidently, and their pricing offers significant value, they might be viable. However, the burden is entirely on you to validate capabilities that Tesla has already demonstrated through documented customer experience.

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.
