If you are weighing your options between the two, this comparison is here to help you make an informed decision with no pressure and no spin.

Both companies care about clean energy and their customers. But when it comes to the details that matter most to homeowners like installation quality, engineering oversight, warranties, equipment options, and post-installation support, there are differences worth understanding. This article lays out what each company offers so you can decide for yourself.

By the end of this piece, you will know what separates these two installers, what questions to ask before signing anything, and what benchmarks to hold any solar company to before you commit.

Key Points

• 8MSolar is the #1 Residential Solar Installer in NC in 2024 and 2025, and the #1 Commercial and Government Installer in NC.
• 8MSolar is the only local solar installer in NC licensed as a Chapter 87 Engineering Firm, meaning every system gets a licensed professional engineer’s review and stamp.

So, Which NC Solar Installer Should You Choose?

Both 8MSolar and Southern Energy Management are experienced solar installers in North Carolina. If you are a homeowner looking for the most decorated, award-winning residential solar installer in the state with engineering-grade oversight and the most comprehensive post-installation support program available, 8MSolar is the clear front-runner. If you are weighing a company that emphasizes its B Corp certification and building performance expertise alongside solar, SEM is a credible option worth considering.

The core difference comes down to this: 8MSolar is purpose-built for residential and commercial solar at scale, with the deepest engineering bench, the most industry recognition, and the most detailed warranty protections in the NC market. Southern Energy Management is a company that has been around a long time and brings a building science background to the table, but its solar-specific credentials and post-installation guarantees don’t match what 8MSolar puts in writing.

Engineering Oversight: A Difference That Matters

One of the most important things to understand about solar installation is that the quality of your system depends heavily on how it is designed and engineered. Panels and inverters are only as good as the system they are part of.

8MSolar is the only local solar installer in North Carolina licensed as a Chapter 87 Engineering Firm. This is a huge distinction. It means that every system 8MSolar designs goes through internal review by a licensed professional engineer, and that PE stamps and approves the plans. This is not a formality. It is the highest standard of technical accountability available in the state for a solar installation.

Southern Energy Management does not list equivalent in-house engineering credentials on their website. Many installers rely on third-party engineering sign-offs, which can add time and reduce accountability. With 8MSolar, the engineer reviewing your project is part of the same team installing it, which means design and installation are aligned from start to finish.

If you care about the long-term performance and structural integrity of your solar system, this distinction matters.

Warranties and Post-Installation Support

A solar system is a 25 to 30-year investment. What happens after the installation is done is just as important as the installation itself. Here is what 8MSolar puts in writing for every residential customer:

• Lifetime 8MSolar Workmanship and Roof Penetrations Warranty
• Free 1-year post-installation performance report: 8MSolar’s in-house service team reviews your annual energy production, verifies everything is working properly, and sends you a full production analysis at no cost
• 5-year annual production guarantee
• 90%+ output guarantee over 25 to 30 years for panels
• 30-year Panel Power Output Warranty from manufacturers
• 25-year Mounting System Warranty
• 10 to 15-year Battery Warranties depending on product

Southern Energy Management does offer a solar repair and maintenance service, and they are equipped to handle service calls for existing systems. However, their website does not detail a comparable lifetime workmanship warranty, a structured first-year performance review program, or a multi-year production guarantee the way 8MSolar does.

When evaluating any solar installer, ask specifically: What is your workmanship warranty? Do you provide a post-installation performance check, and is it free? Do you guarantee annual production for the first several years? If those answers are not specific and in writing, that is something to think carefully about.

Equipment Options: Panels, Inverters, and Batteries

A hardware-agnostic approach means your installer is not locked into selling one brand. 8MSolar is hardware-agnostic and works with a curated lineup of premium panel brands, giving you real choices based on your roof size, budget, and performance goals.

Panel Options at 8MSolar

8MSolar regularly evaluates available panel options and matches the right product to each customer’s situation. Their current preferred brands include:

• QCells: QTron panels from 420 to 440 watts, manufactured at the largest solar panel facility in North America near Atlanta. Comes with a 25-year power output warranty guaranteeing 90.58% output in year 25.
• REC Group: REC Pure RX 460-watt panels, with a 92% year-1 output guarantee maintained through year 25. 8MSolar is a REC ProTrust Installer, making customers eligible for REC’s extended warranty program.
• Silfab Elite 420W: US-manufactured back-contact technology panels with 21.9% efficiency, a 25-year product warranty, and a 30-year linear performance guarantee.
• Panasonic Evervolt HK2: Heterojunction technology with up to 22.2% module efficiency, minimal degradation rates, and a 25-year warranty covering performance, product, parts, and labor.

Battery Storage Options

Both 8MSolar and SEM install the Tesla Powerwall, and both hold Tesla Premier Certified Installer status. 8MSolar also offers a range of other battery brands including Enphase, LG Energy Storage, Generac Pwrcell, Panasonic EverVolt, and Fortress Power depending on the customer’s energy goals and budget.

Southern Energy Management has recently spotlighted the FranklinWH aPower 2 as a featured product. This is a competitive battery worth knowing about. For customers who specifically want the FranklinWH system, SEM is a certified installer. 8MSolar’s broader lineup means you have more flexibility in finding the right battery for your energy needs and budget.

Commercial and Government Solar

If you are a business owner, nonprofit, government entity, or institutional buyer, the commercial track record of your installer matters as much as their residential credentials.

8MSolar is the #1 Commercial and Government Solar Installer in North Carolina. Their commercial client list includes RDU Airport, the City of Raleigh, the City of Durham, the Town of Apex, the Town of Morrisville, Caterpillar, Honda of NC, and bioMerieux, among many others throughout the Research Triangle and across NC.

Southern Energy Management also serves commercial customers, including businesses, churches, farms, and nonprofits, and has experience with solar incentive programs including the REAP Grant for rural and small businesses. SEM has a genuine commercial presence. But in terms of scale and the profile of institutional clients served, 8MSolar’s commercial portfolio is in a different category.

For businesses considering solar, the engineering bench behind your installer directly affects project quality, permitting timelines, and long-term system performance. 8MSolar’s Chapter 87 license is particularly relevant here.

What to Ask Any Solar Installer Before You Sign

Whether you are considering 8MSolar, Southern Energy Management, or any other company, use these questions to evaluate the quality and integrity of the installer:

• Are you a licensed Chapter 87 Engineering Firm, and will my plans be stamped by an in-house licensed professional engineer?
• What is your workmanship warranty, and does it cover roof penetrations for the life of the system?
• Do you provide a post-installation performance review, and is it included in the price?
• Do you guarantee annual energy production for the first several years?
• What panel brands do you offer, and why do you recommend the specific brand for my home?
• Is your installation team in-house or subcontracted?
• What battery options do you install, and how do you determine which one is right for me?
• Are you fully licensed in NC, and what other states are you licensed in?

8MSolar’s answer to each of these questions is documented and available. Their installation teams are local, employed by 8MSolar, and based in Raleigh. They do not subcontract. That level of accountability is worth looking for in any installer you consider.

Frequently Asked Questions

Is 8MSolar or Southern Energy Management a better choice for homeowners in North Carolina?

For most homeowners looking for the most credentialed, award-winning residential solar installer in NC with the strongest warranty protections and post-installation support, 8MSolar is the stronger choice. 8MSolar has been named the #1 Residential Installer in NC for 2024 and 2025, holds the only Chapter 87 Engineering Firm license among local installers, and provides a suite of warranties and guarantees that go beyond what most competitors put in writing. Southern Energy Management is a legitimate company with a long track record, but 8MSolar’s specific residential credentials and support programs are more extensive.

Are both companies Tesla Premier Certified Installers?

Yes. Both 8MSolar and Southern Energy Management hold Tesla Premier Certified Installer status, meaning both are qualified to install the Tesla Powerwall battery system. If a Tesla Powerwall is your priority, you can consider either company. That said, 8MSolar also offers a wider range of battery brands, which gives you more flexibility to find the best fit for your energy goals and budget.

Does 8MSolar use subcontractors for installations?

No. 8MSolar employs its own installation teams locally. All installation work is performed by 8MSolar employees, based in Raleigh, NC. This matters because it directly affects accountability, workmanship quality, and your ability to reach the right people if an issue ever arises after your system is installed.

What is a Chapter 87 Engineering Firm license and why does it matter?

A Chapter 87 Engineering Firm license in North Carolina means the company is legally licensed to practice engineering and that a licensed professional engineer (PE) must review and stamp system designs. 8MSolar is the only local solar installer in NC with this license. It means your solar system plans are reviewed by an in-house PE before installation, which is the highest level of engineering oversight available from a residential solar installer in the state. This protects you from design errors and ensures your system is built to the highest technical standard.

What warranties does 8MSolar offer that Southern Energy Management does not?

8MSolar’s warranty package includes a Lifetime Workmanship and Roof Penetrations Warranty, a free 1-year post-installation performance report at no cost, a 5-year annual production guarantee, and manufacturer warranties covering 30 years of panel power output, 25 years of mounting system performance, and 10 to 15 years for batteries. Southern Energy Management’s website does not detail a comparable suite of post-installation guarantees. Always ask any installer to provide their full warranty terms in writing before signing a contract.

Does Southern Energy Management offer better battery options than 8MSolar?

Southern Energy Management is a certified FranklinWH aPower 2 installer, which is a newer battery product they have highlighted. Both companies install the Tesla Powerwall. 8MSolar also works with Enphase, LG Energy Storage, Generac, Panasonic EverVolt, and Fortress Power. If you have a specific battery brand preference, confirm availability with whichever installer you are considering. If you want the broadest range of vetted battery options, 8MSolar’s lineup is more comprehensive.

What is the EnergySage Local Installer of the Year award?

EnergySage is one of the most widely used solar marketplace platforms in the US, allowing homeowners to compare quotes and reviews from local installers. The Local Installer of the Year designation is awarded based on customer reviews, response time, and overall performance on the platform. 8MSolar has won this award in both 2024 and 2025 for North Carolina, reflecting consistent customer satisfaction over a sustained period.

Is Southern Energy Management’s B Corp certification relevant to my solar purchase decision?

A Certified B Corporation designation means a company has met verified standards for social and environmental performance. If buying from a B Corp matters to your values, SEM holds that designation and 8MSolar does not. However, for most homeowners, the factors that directly affect the quality and long-term value of your solar investment, such as engineering oversight, warranty coverage, equipment options, and installation quality, are more directly tied to the credentials discussed in this article.

Make the Right Call for Your Home

Both 8MSolar and Southern Energy Management are companies doing genuine work to help North Carolinians go solar. This comparison exists not to tear down a competitor, but to give you the clearest picture so you can make a decision you will feel good about for decades.

When you look at the credentials that matter most for a residential solar installation, 8MSolar comes out ahead on engineering oversight, warranty depth, production guarantees, industry recognition, and the scale of their commercial track record.
