Choosing a Solar Company Is One of the Biggest Decisions You'll Make
Going solar is a major investment in your home, your finances, and your future. And while the technology has gotten remarkably reliable, the company that installs your system matters more than most people realize.
The right installer gives you a system that performs beautifully for decades. The wrong one can leave you with headaches, hidden costs, and a system that underdelivers.
California has hundreds of solar companies — from massive national chains to small local operators. So how do you sort through the noise and find the right partner? Here's our honest guide.
1. Check Licensing and Credentials
This is non-negotiable. In California, solar installation requires a C-10 Electrical Contractor license or a C-46 Solar Contractor license from the Contractors State License Board (CSLB).
What to Verify
Active CSLB license: Look up the company at cslb.ca.gov — check that their license is current and in good standing
No complaints or disciplinary actions: The CSLB database shows any filed complaints
Workers' compensation and liability insurance: Protects you if anything goes wrong during installation
NABCEP certification: Not required, but the North American Board of Certified Energy Practitioners certification signals serious commitment to quality
If a company can't show you their license number or dodges the question, walk away.
2. Understand Who's Actually Doing the Work
This is one of the most overlooked factors — and one of the most important.
Many solar companies, especially the big national brands, don't install the panels themselves. They sell the system, then hand the installation off to subcontractors who may or may not meet the same quality standards.
Questions to Ask
Do you use your own installation crews or subcontractors?
How are your installers trained and supervised?
Who do I contact if there's an issue with the installation?
There's nothing inherently wrong with using subcontractors — many reputable companies do. What matters is accountability. You want a company that stands behind the installation whether they did it in-house or through a trusted partner.
At Everysun, we use our own trained installation crews. Every system is installed by people we know and trust, and we personally oversee every project from design to final inspection.
3. Evaluate Equipment Quality
Not all solar panels are created equal, and the equipment a company uses tells you a lot about their priorities.
Panels
Efficiency: Look for panels rated 20%+ efficiency. Higher efficiency means more power from less roof space.
Warranty: Top manufacturers offer 25-year product and performance warranties.
Appearance: If aesthetics matter to you (they should — these will be on your roof for 25+ years), look for sleek all-black panels rather than the old-style blue-and-silver grid pattern.
Country of origin: US-made panels often come with better supply chain reliability and quality control.
Inverters
Microinverters vs. string inverters: Microinverters (one per panel) offer panel-level optimization and monitoring. String inverters are simpler but a single failure affects the whole system.
Warranty length: 12–25 years depending on brand and type.
Battery Storage
If you're adding a battery system, ask about capacity, round-trip efficiency, warranty, and how well it integrates with the solar panels and your home's electrical system.
4. Look at Reviews and Reputation
In the age of the internet, there's no excuse for not researching a company's track record.
Where to Look
Google Reviews: Look at both the overall rating and individual reviews. Pay attention to how the company responds to negative feedback.
Yelp: Common in California for contractor reviews
BBB (Better Business Bureau): Check for complaints and how they were resolved
Estimated production: How many kWh per year will the system produce?
The cheapest quote isn't always the best deal. A system installed with better equipment, stronger warranties, and more attentive service may save you more money over its lifetime — even if it costs a bit more upfront.
7. Ask About the Full Process
A great solar company is organized, communicative, and transparent about every step. Before signing, ask:
How long will it take from contract to panels producing power?
Who handles permitting and utility interconnection?
Will I have a single point of contact throughout the project?
What happens after installation — who do I call for support?
If the company can clearly walk you through their process and timeline, that's a good sign. If they're vague or evasive, that tells you something too.
8. Think Long-Term: Will This Company Be Around?
Your solar system will be on your roof for 25+ years. You want a company that will be around to honor warranties, answer questions, and provide service.
Signs of a Company That's Built to Last
Multiple years of operation with consistent reviews
Local presence (not just a national call center)
Invested in the community — local offices, local crews
Transparent about their business model and financials
Growing through referrals and reputation, not just aggressive marketing
Why Everysun Is Different
We started Everysun with a simple belief: California homeowners deserve better than what the solar industry has been giving them. Too many broken promises, too many high-pressure sales pitches, too many companies that disappear after installation.
Here's what makes us different:
Own installation crews: Every system is installed by our trained team — no anonymous subcontractors
Premium equipment: We use high-efficiency, US-made all-black solar panels and top-tier inverters
Scandinavian quality standards: Our founders built solar companies in Northern Europe, where quality isn't optional — it's the foundation
Transparent pricing: We show you exactly what you're paying for and what you'll save. No games, no hidden fees.
20-year installation warranty: We don't just install and leave. We stand behind our work for decades.
Local and accessible: We're based in Southern California and we're here to stay. When you call, a real person answers.
