8M Solar Reviews (2026): Real Customer Feedback, Complaints & Red Flags

Thinking about going solar in North Carolina? You have likely seen the name 8MSolar. This guide breaks down 8M Solar reviews from Google, the BBB, SolarReviews, EnergySage, and smaller sites. You will see what buyers love, what goes wrong, and how to check a quote before you sign.

We do not sell solar. We do not take payment from installers. Our goal is simple: help you make a calm, informed choice.

What Do 8M Solar Say at a Glance?

Most feedback is very positive. A small number of buyers report serious problems.

Quick answer:

• Ratings are high on most big sites, often 4.6 to 5.0 stars.
• The BBB gives the firm an A+ rating. It has been accredited since November 2017.
• The BBB shows just 1 complaint in the last 3 years (at the time of writing).
• Praise centers on fair prices, clean installs, and help with permits and utility paperwork.
• Negative stories focus on system sizing, delays, deposits, and warranty labor fees.
• 8MSolar is a regional installer. It mainly serves North Carolina and Virginia.

The short version: 8M reviews point to a strong local installer. Still, the bad reports are worth reading. They show where any solar deal can break down.

8M Solar Company Reviews: How Does It Rate Across Platforms?

Ratings vary by site. Each platform collects reviews in its own way. That is why one site can show 5.0 while another shows a much lower score.

Platform	Rating Snapshot
Google	About 4.9 stars from roughly 580+ reviews (shown on the company site)
SolarReviews	About 4.6 stars from 115 reviews
BBB	A+ rating; 5.0 average from 7 customer reviews
EnergySage	Mostly 5-star reviews; listed since 2015
Nextdoor	Many neighbor recommendations
BestCompany	2 reviews, both negative (1 and 2 stars)

Ratings change often. Figures were checked in October 2026. Confirm them on each site before you decide.

Why Do Ratings Differ So Much by Site?

A few things shape these numbers:

• Review volume. Google has hundreds of reviews. BestCompany has two. Small samples swing hard.
• Who asks for reviews. Firms often invite happy buyers to post on Google.
• Where upset buyers go. People with problems tend to look for complaint sites.
• Moderation rules. Each site filters and verifies posts in a different way.

So when you read 8M Solar company reviews, look at the full spread. Do not trust one score alone.

What Do 8M Solar Customer Reviews Praise Most?

Positive posts are detailed and consistent. The same themes show up on site after site.

Competitive Pricing

Many buyers collected three or more quotes. A large share say 8MSolar came in lowest. One EnergySage reviewer chose not to buy solar at all. Even so, they said the pricing was fair and the team did not oversell savings.

Clean, Fast Installs

Reviewers often say the crew finished in one day. They describe tidy wiring and careful cleanup. One BBB reviewer said the county inspector praised the job as one of the best he had seen.

Help With Paperwork

Solar comes with a lot of forms. Buyers like that 8MSolar handles:

• County permits and inspections
• Duke Energy interconnection
• HOA approvals
• Rebate filings, such as Duke’s PowerPair program

Honest Sales Approach

Several 8M Solar customer reviews mention low pressure. Buyers say the sales team answered many questions. They also say the staff explained limits, like shade or roof direction, in plain terms.

Battery and EV Charger Integration

Many recent installs pair panels with a Tesla Powerwall 3. Some owners later added an EV charger. They report that the system works smoothly in one app.

What Are the Most Common 8M Solar Complaints?

Negative reviews are rare, but they are serious. Here are the main themes we found.

Undersized Systems and Missed Savings

One buyer said the system was sized at about half of what the home needed. They had been told to expect a net-zero bill. Instead, they still paid a large utility bill.

Why it matters: Sizing depends on your past usage, roof space, and shade. Ask for the production estimate in writing. Then check it with a free tool like NREL’s PVWatts.

Installation Delays and Equipment Shortages

Another buyer signed in late 2024. They said a Powerwall was out of stock. The firm asked them to accept a partial install and pay early. The buyer refused, and the install slipped to 2025.

That delay cost the buyer a tax-year deadline they had asked for from the start. Timing still matters today. Utility rebates, like PowerPair, have limited space.

Deposit and Cancellation Disputes

The same buyer paid a $3,000 deposit. They felt the deposit was used as leverage to keep them in the deal. They said a neighbor with no deposit faced no such fee.

Subcontracted Crews and Electrician Concerns

One reviewer said the crew was not employees, as promised. They also said no licensed electrician came to the site. Note that a buying guide from 2025 says 8MSolar uses an in-house team. Ask who will do your install and get it in the contract.

Warranty Labor Charges

One owner’s inverter failed after about 3 years. The part was covered. But they were charged labor to install it. They admitted the contract allowed this. Still, they felt it was unfair.

Communication After the Sale

A few buyers said follow-up slowed once they paid. One said the firm threatened to walk away when they raised concerns. These are one-sided reports, so weigh them with care.

Most 8M Solar complaints come from a handful of posts. That is a small share of hundreds of reviews. Yet each one points to a contract term worth checking.

8M Solar Reviews and Complaints: What Patterns Stand Out?

When you line up the good and bad posts, a few clear patterns appear.

Theme	Good Reviews	Bad Reviews
Price	Often lowest quote	Hidden labor fees later
Install	Clean, one-day jobs	Partial installs offered
Timing	Smooth permits	Missed deadlines
Sizing	Output matches estimate	System too small
Service	Responsive team	Slow follow-up after payment

Key Takeaways From the Data

• Most buyers are happy. Praise outnumbers complaints by a wide margin.
• Problems cluster after signing. Delays, deposits, and labor fees are the main pain points.
• Battery supply drives delays. Powerwall stock affected some 2024 jobs.
• Contract details matter. Many disputes trace back to fine print the buyer did not expect.

In short, Its reviews and complaints tell a fair story. The company does many things well. But your contract is what protects you when something goes wrong.

How Much Does 8M Solar Cost, and How Can You Pay?

8MSolar does not post prices online. Review sites say its quotes tend to come in below the North Carolina average. Your price will depend on system size, equipment, roof type, and battery choice.

What Payment Options Are Available?

Option	What to Know
Cash	Lowest total cost; you own the system
Solar loan	Third-party lender; you own the system
Lease or PPA	A 2025 guide said these are not offered; confirm

If you plan to finance, read the loan terms line by line. Watch for dealer fees built into the price. If you are already behind on a solar loan, our guide on solar project debt workout options explains what help exists.

Sample Cost Calculation (Illustration Only)

This example uses assumed prices. It is not a quote.

Item	Amount
7 kW solar system (assumed $2.80/watt)	$19,600
13.5 kWh battery (assumed)	$12,000
Total before incentives	$31,600
PowerPair solar part (7 kW × $360)	−$2,520
PowerPair battery part (13.5 kWh × $400)	−$5,400
Estimated net cost	$23,680

Your real numbers will differ. Get at least three written quotes and compare the cost per watt.

What Warranties Does 8M Solar Offer?

Strong warranty coverage is one of the most praised features in reviews.

Coverage	Typical Term
Workmanship	Lifetime (8MSolar warranty)
Roof penetrations	Lifetime (8MSolar warranty)
Solar panels	25 to 30 years (maker warranty)
Inverters/microinverters	12.5 to 25 years (maker warranty)
Racking and mounts	25 years

What Is Not Covered?

• Labor on some part swaps. One owner paid labor for a covered inverter.
• Power output. A 2025 review noted no production guarantee.
• Damage from other trades. A roofer or storm may void parts of the coverage.

Ask for the full warranty document before you sign. “Lifetime” can have limits, such as only while you own the home.

If panels or crews damage your roof, you may have options. Learn more in our guide to solar panel property damage claims.

What Changed for Solar Buyers in 2026?

The rules changed a lot this year. Some older reviews mention savings that no longer apply.

The 30% Federal Tax Credit Has Ended

The Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025. A 2025 federal law ended it early. If you buy and own a system in 2026, you get no federal credit.

Red flag: Any sales pitch that promises a 30% federal credit for a 2026 install is wrong. Check the IRS Residential Clean Energy Credit page to confirm.

Duke Energy PowerPair Is Now the Biggest Incentive

PowerPair pays a one-time rebate for new solar plus battery systems.

• 0.36perwatt-ACofsolar,upto10kW(3,600 max)
• 400perkWhofbattery,upto13.5kWh(5,400 max)
• Total of up to $9,000

Space is limited and first come, first served. Duke Energy Progress capacity has filled. Some installers report the program ends in December 2026. Confirm status with Duke Energy before you count on it.

North Carolina Property Tax Exemption

North Carolina does not tax the value solar adds to your home. There is no state solar income tax credit.

For general guidance on home energy choices, visit the U.S. Department of Energy.

How Long Does an 8MSolar Install Take?

Reviewers say the install day itself is short. Many crews finish in one day. The full project takes longer because of permits and utility steps.

Stage	Who Handles It
Site visit and design	Installer
Contract and deposit	You and the installer
Permits and HOA approval	Installer, with county and HOA
Utility interconnection	Installer and your utility
Install day	Installer crew
County inspection	County inspector
Permission to operate	Your utility

What Can Slow a Project Down?

• County inspection backlogs. One EnergySage reviewer said the only delay came from the county, not the installer.
• Battery stock. Powerwall supply caused some 2024 delays.
• HOA review. Some HOAs take weeks to approve plans.
• Utility queues. Interconnection can take time in busy months.

Tip: Ask for a written timeline with each stage. Ask what happens if a rebate or deadline is at risk.

Is Solar Still Worth It in North Carolina Without the Tax Credit?

For many homes, yes. But the math is tighter than it was in 2025. The 30% federal credit is gone, so payback takes longer.

What Still Helps the Numbers?

• PowerPair rebate of up to $9,000 for solar plus a battery
• No added property tax on the value solar adds
• Rising utility rates that make each solar kWh worth more over time
• Battery programs from Duke Energy that pay monthly bill credits

When Solar May Not Pay Off

• Your roof gets heavy shade most of the day.
• Your power use is low.
• Your utility has low rates, like some electric co-ops.
• You plan to move in a few years.

One EnergySage reviewer chose not to buy for these reasons. They praised the quote but said their home was a poor fit. That kind of honest feedback appears often in reviews, and it is worth noting.

Before you decide, compare your yearly bill with the quoted system cost. Then work out how many years it takes to break even.

Are 8M Reviews Trustworthy?

Mostly yes, but read them with a critical eye. Here is why.

Signs the Reviews Are Real

• Many posts include names, dates, and project details.
• Reviews appear on sites the firm does not control, like the BBB and SolarReviews.
• Some reviews are mixed. Fake reviews are rarely mixed.

Reasons to Stay Careful

• The company’s own pages show only hand-picked testimonials.
• Some review sites let firms request reviews from happy buyers.
• A few complaint sites have very small samples.

Tip: Sort reviews by “newest” and “lowest.” Recent negative posts tell you the most about how the firm treats buyers today.

Using Reviews and Complaints to Vet Your Quote

Use what buyers learned the hard way. Before you sign, work through this checklist.

Pre-Signing Checklist

• Get the production estimate in writing (yearly kWh).
• Compare it with your last 12 months of usage.
• Ask who will do the install: employees or subcontractors.
• Ask if a licensed electrician will be on site.
• Get the deposit amount and refund rules in writing.
• Ask what happens if equipment is out of stock.
• Ask if warranty work includes labor.
• Get a target install date in the contract.
• Confirm which rebates you qualify for, and who files them.
• Check the contractor license with the NC state board.

Questions to Ask Your Sales Rep

1. How did you size my system?
2. What shade or roof issues did you find?
3. What bill savings do you expect, and how sure are you?
4. What happens if my install misses a rebate deadline?
5. Can I cancel, and what will it cost?

You can run your own output check with free tools from the National Renewable Energy Laboratory. Matching these numbers to the quote is one of the best ways to use 8M Solar reviews and complaints wisely.

How Do You Escalate 8M Solar Complaints?

If something goes wrong, act fast and keep records. Most issues can be fixed with clear steps.

Step-by-Step Escalation

1. Write it down. Save emails, texts, photos, and your contract.
2. Contact the company in writing. Ask for a reply by a set date.
3. File with the BBB. 8MSolar is accredited, so it has agreed to respond.
4. Contact the NC Attorney General. Its consumer protection office takes complaints.
5. Talk to a lawyer. This makes sense for large losses or contract disputes.

When to Get Legal Help

• You want out of the deal. See how to get out of a solar contract and what it may cost.
• You suspect false promises. A solar fraud attorney can review misleading sales claims.
• Your roof or home was damaged. Keep photos and repair quotes.
• Someone was hurt during the install. Learn about solar installation injury lawsuits.
• You have a lease in another state. Our guide to solar lease buyouts in California explains how exit terms often work.
• Many buyers share the same issue. Group cases may apply. Track updates in our solar panel class action lawsuit 2026 guide.

We have found no class action against 8MSolar as of October 2026. Most 8M Solar complaints we saw were single-buyer disputes.

Final Verdict on 8M Solar Company Reviews

8M Solar Reviews looks like one of the better-rated local installers in North Carolina. Ratings are strong. The BBB record is clean. Buyers often praise its prices, crews, and paperwork help.

The weak spots are real but narrow. They include delays tied to battery stock, deposit terms, and labor on warranty repairs. Each of these can be handled with a clear contract.

Bottom line: 8M Solar company reviews support adding 8MSolar to your short list. Get at least three quotes. Read every term. And with no federal credit in 2026, make sure the savings still work for your home.
