Knowing how to choose a solar installer is the most important decision in your whole solar project — more important than the brand of panel on your roof. A great installer designs the right system, handles permits and inspections, and stands behind the work for decades. A bad one leaves you with a poorly performing system and no one to call. Here are seven things to check before you sign anything.
1. Licensing and Insurance
Your installer should be a fully licensed and insured contractor in your state. This protects you if something goes wrong during installation and confirms they are qualified to do electrical and roofing work. Ask to see it — a reputable company will share proof without hesitation.
2. Local Track Record and Reviews
Look for a company with real, recent reviews from customers in your area — on Google, the BBB, and platforms like Yelp or EnergySage. A strong local reputation is hard to fake. Be cautious of national lead-generation companies that subcontract the actual work to whoever is cheapest that week.
3. Who Actually Does the Install
Ask directly: does the company use its own trained crews, or does it subcontract? In-house crews mean the people who design your system are the people who install it and answer the phone afterward. That accountability matters when you need service years down the road.
4. Warranties
There are two warranties that matter: the equipment warranty (panels and inverters, usually 25 years) and the workmanship warranty (the installer’s own guarantee on the labor and roof penetrations). Make sure both are clearly spelled out in writing, and that the company is likely to be around to honor them.
5. Clear, Itemized Pricing
A trustworthy quote breaks down exactly what you are paying for: design, equipment, installation, permitting, and activation. Be wary of vague all-in numbers or prices that change every conversation. You should also get a realistic production and savings estimate based on your actual energy use, not a generic figure.
6. Honest Financing Options
A good installer explains your options plainly — cash, a $0-down loan, and how each affects your long-term cost — without pressure. Walk away from anyone who rushes you, uses high-pressure “today only” tactics, or won’t put the numbers in writing. See how we lay this out on our solar cost & financing page.
7. They Handle the Whole Process
The best installers manage everything: system design, permits, utility interconnection, inspection, and final activation. You should not have to chase down paperwork or coordinate with your utility yourself. Ask them to walk you through their process start to finish.
Red Flags to Watch For
As you learn how to choose a solar installer, a few warning signs should make you pause. Be cautious of door-to-door reps using high-pressure, “sign today or lose the deal” tactics — a fair solar offer is still fair next week. Watch out for quotes that won’t put production estimates, equipment brands, or warranty terms in writing. Be skeptical of promises that sound too good to be true, like “free solar” or guaranteed savings with no details behind them. And if a salesperson can’t clearly explain who installs the system, who you call for service, and exactly what you’re financing, treat that as your answer. The right installer earns your trust with straight answers, not urgency — and is happy to give you time to compare.
