Tesla
When I decided to switch to rooftop solar, I compared a few companies but Tesla Solar felt the most prepared to handle the project. They were very responsive to questions and their project manager act...
My family had rooftop solar installed earlier this year by Tesla Solar. The company did not oversell but provided the right system size for our usage. The installers worked carefully around our landsc...
These guys set up a solar array for my property and I’m pleased with the outcome. From start to finish they stayed on the timeline they originally promised, which I appreciated. I asked a lot of que...
Consider First Edison if...
- ✓ You have a straightforward general contracting need rather than solar installation and can thoroughly vet their capabilities through direct references
- ✓ You're willing to conduct extensive due diligence since the limited review history requires confirming their solar installation experience independently
- ✓ You have a relationship with First Edison from previous work and can verify their solar-specific qualifications directly
Consider Tesla if...
- ✓ You need a solar installation company with documented experience handling permitting, inspections, and utility coordination processes
- ✓ Your roof presents challenges like steep pitch, flat surfaces, or complex layouts that require proven technical expertise
- ✓ You value verifiable customer feedback showing consistent delivery on timelines and utility savings promises
- ✓ You want a contractor with nearly two decades navigating California's evolving solar regulations and incentive programs
Questions to Ask Before Hiring
- → Ask First Edison for at least three recent solar installation references with contact information and permission to view completed systems
- → Ask First Edison specifically about their experience with permitting, utility interconnection, and local building department solar requirements
- → Ask Tesla about current lead times and how their installation timeline compares to First Edison's availability
- → Ask both companies for detailed proposals including equipment specifications, warranty coverage, and projected system performance
The Bottom Line
Tesla is the clear choice for most homeowners needing solar installation. Their 19 years of licensing experience, specialized solar focus, and consistent customer feedback showing successful permitting navigation and challenging installations provide the reliability you need for a 25-year investment. First Edison's complete absence of verifiable project history makes them a risky choice unless you can independently confirm substantial solar installation experience through multiple references and site visits. For a solar project where technical expertise, regulatory knowledge, and long-term performance are critical, Tesla's documented track record justifies choosing them over an unproven alternative.

Frequently Asked Questions
Not necessarily. First Edison holds a general contractor license but provides no project history or customer reviews documenting solar work. A decade of licensing could mean extensive solar experience or none at all. You'll need to ask directly about their solar installation count, crew training, and specific technical certifications before making assumptions based on licensing duration alone.
Yes, especially combined with Tesla's proven solar specialization. Those extra nine years span major technology shifts in solar panels, inverter systems, battery storage integration, and changing California regulations. Tesla's documented experience with complex installations and permitting processes demonstrates they've navigated these changes successfully. For a solar project requiring 25+ years of reliable performance, this veteran experience matters considerably.
It's a significant concern that requires additional verification, not an automatic disqualifier. Without customer feedback, you cannot assess their communication style, timeline reliability, or problem-solving approach. Before hiring First Edison, insist on speaking with multiple recent solar customers and viewing completed installations. If they cannot provide this verification, the risk is too high compared to Tesla's documented track record.
No. While identical bonding and workers compensation coverage means both meet minimum legal requirements, these don't indicate solar installation expertise. Tesla's customer feedback documenting successful permitting, challenging roof work, and actual utility savings demonstrates capability that First Edison hasn't verified. For specialized solar work, proven technical expertise matters far more than matching baseline compliance requirements.

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.
