Most homeowners worry about picking the wrong solar installer and for good reason. Your solar panels should last 25+ years, which means you need a company that’ll still be around when you need them. Here’s exactly what to look for.
The Real Problem: Not All Solar Companies Are Built the Same
You’ve probably noticed solar companies popping up everywhere. Some are solid, experienced installers. Others? They’re just sales teams who outsource the actual work to whoever bids lowest. The difference matters a lot.
A bad installer means surprise costs, shoddy workmanship, and zero support when something breaks. A good one? They’ll save you money, stand behind their work, and be there for decades.
5 Must-Check Factors Before You Sign Anything
1. How Long Have They Actually Been in Business?
Look for companies with at least 5-10 years of experience in your area. Longevity proves two things: they do quality work (or they’d be out of business), and they’ll likely be around to honor warranties.
Red flag: A company offering a 25-year warranty but only 3 years in business? That warranty might be worthless if they fold.
2. Do They Use Their Own Installation Crews?
Some companies sell you panels, then hire random subcontractors to install them. This creates quality control nightmares and finger-pointing when problems arise.
Ask: “Are your installers full-time employees? Are they NABCEP-certified?” (That’s the gold standard for solar professionals.)
3. What Do Real Customers Say?
Check Google Reviews, Better Business Bureau, and SolarReviews.com. Look for patterns; one bad review isn’t a dealbreaker, but consistent complaints about ghosting customers or rushed installations? Run.
Bonus tip: A 20-year-old company with only 5 reviews is suspicious. Where are all their customers?
4. What Equipment Are They Installing?
Quality panels and inverters matter. Reputable installers use brands like Qcells, Canadian Solar, Enphase, or SolarEdge, not off-brand equipment you’ve never heard of.
Ask: “What brands do you install and why? What warranties come with the equipment?”
Panels should have 25-year performance warranties. Microinverters should come with 25-year coverage; string inverters need at least 10 years.
5. What Happens If Something Goes Wrong?
This is the question most people forget to ask and it’s the most important.
You need clear answers to:
- How long is your workmanship warranty?
- Who handles repairs if the inverter fails?
- What are response times for service calls?
- Are labor costs covered under warranty?
If they dodge these questions, that’s your answer.
What You Should Actually Pay
Good solar costs around $3.00–$3.50 per watt for a cash purchase. Anything under $2.60/watt? They’re probably cutting corners. Over $4.00/watt? You’re overpaying (unless financing is included, which inflates the price).
Example: A typical 6 kW system should cost $18,000–$21,000 before incentives. After the federal tax credit (30%), that drops to $12,600–$14,700.
Beware companies pushing “free solar” or “no money down” without explaining the real terms. There’s no such thing as free solar; you’re either buying, financing, or leasing. Know which.
Comparison: Local vs. National Solar Companies
| Factor | Local Company | National Company |
| Customer Service | Personalized, responsive | Call center support |
| Installation Crew | Often in-house employees | Frequently subcontracted |
| Long-term support | Usually excellent | Depends on local presence |
| Pricing | Competitive, transparent | Can be higher due to overhead |
| Best for | Homeowners buying cash/loan | Homeowners leasing/PPAs |
Bottom line: Local companies typically provide better long-term value and service for homeowners purchasing their systems.
FAQ: Quick Answers to Common Questions
How do I know if a solar company is legit?
Check their license with your state contractor board, verify NABCEP certification, and read recent customer reviews on neutral sites like Google and BBB.
Should I get multiple quotes?
Yes, at least 3. Compare not just price, but equipment quality, warranties, and customer service reputation.
What if the company goes out of business?
Equipment warranties from manufacturers still apply. That’s why choosing quality brands matters. But workmanship warranties become worthless if the installer folds.
Can I negotiate solar pricing?
Sometimes, but be wary of companies that slash prices immediately; they may be cutting corners. Focus on value, not just the lowest bid.
How long does installation take?
2-3 months from signing to flip-on, including permitting and inspections. The actual installation usually takes 1-3 days.
Do I need a new roof first?
If your roof has less than 10 years of life left, replace it before solar. Removing and reinstalling panels later costs $3,000–$5,000.
