Picking a solar installer might be the most important decision in your entire solar journey — more than which panels you buy or how big the system is. A well-installed system with average panels will outperform a great system that was slapped on your roof by someone who won’t answer the phone in two years.
In the South, that decision carries extra weight. Between utility-specific net metering rules, hurricane season, and a wave of out-of-state installers who flooded the Southeast market after the Inflation Reduction Act and have since quietly closed up shop, Southern homeowners have more reason than most to be choosy.
Here’s exactly what to look for — and the one question most people never think to ask but should.
Local Experience Matters More Than National Brand Recognition
The solar industry is full of large national companies with polished websites and sales teams that work every market in the country. That’s not necessarily bad — but it does mean their installation crews may be subcontractors who’ve never worked with your specific utility, and their customer service line may route to a call center with no knowledge of Georgia Power’s interconnection backlog or Duke Energy’s current net metering structure.
A regional installer who’s done hundreds of projects in your area knows which utilities move fast and which drag their feet on “permission to operate.” They know the local building departments, the roof styles common to your neighborhood, and the specific shading patterns that affect production in your climate.
When you ask an installer how many systems they’ve completed in your county — not your state, your county — you’ll quickly learn whether they’re genuinely local or just locally licensed.
Credentials to Verify Before You Sign Anything
NABCEP Certification
The North American Board of Certified Energy Practitioners (NABCEP) PV Installation Professional credential is the industry gold standard. It requires documented field experience, passing a rigorous exam, and ongoing continuing education. A reputable installer will have at least one NABCEP-certified professional involved in your system design or installation. Ask to see the certificate number — it takes 30 seconds to verify on the NABCEP website.
State Electrical Contractor License
Solar installation involves live electrical work, which means it falls under electrical contractor licensing laws in every Southern state. In Georgia, that means a licensed electrical contractor must either do the work or directly supervise it. In Florida, there’s a specific solar contractor specialty license. Ask for their license number and look it up with your state’s contractor licensing board. If they can’t produce it, walk away.
General Liability and Workers’ Comp Insurance
If a crew member falls off your roof and the company doesn’t carry workers’ compensation, you could be on the hook. Ask for a certificate of insurance and confirm it’s current. Any legitimate installer will have this ready without hesitation.
What to Ask During Your Quotes
Plan to get at least three quotes. That’s not just about finding the lowest price — it’s about learning the market and seeing how different companies explain the same product. Here are the questions worth asking each one:
How long is your workmanship warranty? Panel manufacturers cover their equipment for 25 years, but that doesn’t cover the labor or the roof penetrations the installer made. A workmanship warranty — typically 5 to 10 years — should be in writing. If they don’t offer one, ask why.
Who actually installs the system? Many larger companies use subcontractors for installation. That’s common and not necessarily a problem, but you should know. The workmanship warranty should explicitly cover whoever does the physical work.
What monitoring system is included, and what happens to it if your company closes? Most modern inverters (Enphase, SolarEdge, SMA) include cloud-based monitoring. Confirm it’s included and ask whether monitoring access depends on the installer’s continued existence — some platforms let you transfer ownership directly to the manufacturer.
What’s your current interconnection timeline with my utility? This varies widely across the South. Some utilities have backlogs measured in months. A good installer gives you a realistic estimate and explains exactly what they handle versus what you need to manage.
The Battery Storage Question You Should Always Ask
Here’s the question that separates a forward-thinking installer from one who’s just selling panels: “Do you install home battery storage, and which systems do you carry?”
This matters for two reasons that are specific to Southern homeowners.
First, net metering is not permanent. Georgia Power’s current structure has already been under review, and utilities across Florida and the Carolinas have reduced export compensation in recent years. Homeowners who pair solar with battery storage are insulated from those changes — they can store their excess production and use it at night rather than depending on favorable export rates that may not last.
Second, grid outages are a real part of life in the South. Tropical storms, ice storms, and the occasional prolonged heat event can take down power for days. A standard grid-tied solar system with no battery storage goes completely dark the moment the grid fails — even when the sun is shining — because of safety requirements that prevent back-feeding a downed grid. A battery changes that entirely.
Systems like the EcoFlow PowerOcean (affiliate link) are designed as AC-coupled additions that can be integrated with existing solar systems, making them compatible regardless of which panels or inverters you already have. An installer who carries and installs storage solutions is thinking about your long-term energy independence, not just today’s sale.

Red Flags That Should Give You Pause
Unsolicited door-to-door sales with same-day pressure. Reputable installers don’t need to doorknock for business. If someone shows up unannounced and pushes you to sign before the day is out, take that as a signal to slow down, get other quotes, and read the fine print carefully.
A quote that’s dramatically below the others. Solar pricing has stabilized significantly. If one installer is coming in 25–30% cheaper than everyone else, it’s worth understanding why — lower-tier panels, cheaper inverters, or a newer company that’s buying market share and may not be around to honor a workmanship warranty in year 7.
Vague answers to direct questions. A licensed, experienced installer can answer every question in this guide without hesitation. If you’re getting runaround answers on license numbers, insurance, or warranty specifics, that tells you something about how they’ll handle a problem after installation.
Bottom Line
The right installer for your Southern home is local, licensed, insured, and transparent — and they’ll have a real answer when you ask about battery storage. Get three quotes, verify the credentials, and ask the battery question. It’ll tell you more about their competence and long-term thinking than anything else you can ask.
