Green Power Energy earns the top spot because everything we checked holds up, and its customers agree. Across 940 reviews on BBB, EnergySage, and SolarReviews it averages 4.9 stars, with just 10 BBB complaints in three years. Both of its state licenses are active, a NABCEP-certified installation professional works out of its Annandale headquarters, and it holds Platinum standing in Enphase's installer network.

The trade-offs are scale and paperwork: its footprint in the state's install records is the smallest on this page, and its 25-year workmanship warranty is the company's own published term. Get it in writing with your quote.

SunnyMac has held its New Jersey contractor registration since June 2010 and sits near the top of the state's own install data, with 7,193 program installs weighted toward Camden, Burlington, and Gloucester counties. Its warranty is the plainest commitment on this page: 25 years on both equipment and workmanship, in exactly those words, with a modest 27 BBB complaints in three years.

Two things to settle before signing: no electrical permit appears under the company's own name in the state registry, so ask which licensed contractor pulls your permit. The company is also headquartered in Wilmington, Delaware, so confirm which office handles your service calls.

No company has installed more residential solar in New Jersey's program records than Trinity: more than 12,000 projects under the current incentive program and over 24,000 under the legacy program, reaching back to 2003, across all 21 counties. Both state licenses are active, and its BBB accreditation dates to 2001.

Scale shows in the service record: 227 BBB complaints in three years and a 3.4 review average across major platforms. Its warranty language also varies by page and product; the floor across its own materials is five years, so get your specific term in writing before you sign.

EMT is the youngest company on this page and the fastest-moving for its size: nearly 4,900 installs in the state's program records, 1,398 of them in the past year. It advertises eight South Jersey counties, but state records show completed projects in all 21 (including hundreds in Bergen and Middlesex), so North Jersey homeowners can ask too. Its contractor registration and electrical permit are both active, and it holds Enphase Platinum standing.

Weigh the reviews with care: its strongest number, a 4.9 Google average, comes from listings we could not confirm directly, while its BBB average is 4.74 across 106 reviews. No NABCEP-certified staff, a B+ BBB rating, and warranty claims that range from five to fifteen years round out the picture. Five years is the number we count.

Momentum Solar has real strengths: a contractor registration held since January 2010, an active electrical permit, a NABCEP-certified professional, Platinum standing with Enphase, and more than 7,000 installs in the state's program records across all 21 counties.

Customer feedback is why it ranks fifth. Its BBB profile shows 590 complaints in three years and a 2.05 review average, with 2.71 on SolarReviews. The A+ letter grade measures complaint handling, not satisfaction. The company also publishes no workmanship-warranty term; independent reviews report 10 years, so get yours in writing before signing.

Questions to Ask a New Jersey Solar Installer

Ask every company the same six questions and compare the answers side by side. Vague answers are themselves an answer.

  1. 1

    Are Your Installers Employees or Subcontractors?

    In-house crews mean one company owns the workmanship warranty. If work is subcontracted, ask who you call when a roof leak appears in year three.

  2. 2

    What Exactly Does the Workmanship Warranty Cover?

    Get the length in writing and confirm whether labor, roof penetrations, and inverter replacement are included. Panel warranties come from the manufacturer, not the installer.

  3. 3

    What Is the Total Cost per Watt, All-In?

    Divide the full contract price (permits, equipment, and labor included) by system size in watts. It's the only number that makes competing quotes comparable.

  4. 4

    What Production Estimate Are You Guaranteeing?

    Ask for annual kWh output and whether the company pays you if the system underproduces. An estimate with no guarantee is a sales figure.

  5. 5

    How Will My PSE&G, JCP&L, or Atlantic City Electric Interconnection Work?

    Your utility's application timeline and net-metering process drive both savings and switch-on date. An installer who can't explain them hasn't done many local jobs.

  6. 6

    What Happens to My Warranty if You Go Out of Business?

    Manufacturer warranties survive an installer's closure; workmanship warranties usually don't. Ask whether a third-party insurer backs it.

How to Read a New Jersey Solar Quote

Every quote opens with system size in kilowatts and an annual production estimate in kWh. Check the estimate against your last 12 utility bills. An oversized system inflates the price faster than the savings.

Next comes the equipment list: panel brand and wattage, inverter type, racking, and any battery. Manufacturer warranties are printed here; the installer's own workmanship warranty should appear as a separate line with a number of years on it. If it doesn't, ask why.

The gross system cost is the pre-incentive total. Divide it by system size in watts to get cost per watt, the one number that makes competing quotes comparable. Permitting, interconnection, and inspection fees should be itemized, not buried in a "soft costs" line.

On financed quotes, find the APR, term, and any dealer fee baked into the price, and ask for the cash price and financed price side by side.

Finally, the quote should commit to registering your system with New Jersey's SuSI program. That registration earns your SREC-II payments for 15 years, and the installer should file it, not you.

Red Flags When Choosing a Solar Installer

Most solar complaints trace back to the sales process, not the panels. Walk away if you see any of these.

"This Price Is Only Good Today"

Legitimate installers hold quotes for 30 days. Same-day pressure exists to stop competing bids.

A Quote With No Cost-per-Watt Breakdown

A monthly payment alone can't be compared to anything. Ask for gross cost, size in watts, and itemized fees.

Promises of "Free Solar" or a Zero Electric Bill

No system eliminates your bill: utilities charge fixed connection fees. "Free solar" usually means a lease or PPA where someone else owns the panels.

No Active NJ Contractor Registration

Installers need an active NJ Home Improvement Contractor registration, and solar electrical work requires a licensed electrical contractor. Look both up in the state's license lookup before signing.

Large Deposits Before Permits Are Filed

Payment before design and permitting begin puts your money at risk. Reputable installers bill at milestones.

New Jersey law · Your right to cancel

You can cancel any New Jersey home improvement contract, for any reason, before midnight of the third business day after you receive your copy, with a full refund within 30 days. That's state law under the Contractors' Registration Act (N.J.S.A. 56:8-151), which also requires contracts over $500 to be in writing. A sale signed in your home is separately covered by the FTC's federal Cooling-Off Rule (16 CFR 429.1), its own three-business-day cancellation right. If a dispute involves your utility or interconnection, the NJ Board of Public Utilities' Division of Customer Assistance takes complaints at (800) 624-0241 or via its online complaint form.

How We Rank Solar Companies

Rankings are never paid for. Every installer is scored across five published, weighted criteria, each computed on primary-source records.

1

Customer Satisfaction — 30%

Volume-weighted review average across BBB, EnergySage, and SolarReviews, reduced where a company draws heavy BBB complaints relative to its install volume.

2

NJ Program Activity — 20%

Installed-project volume in New Jersey's own solar program records.

3

Credentials — 20%

Only credentials we can verify count: an active contractor registration, an active electrical permit, NABCEP-certified staff, and manufacturer standing confirmed in the manufacturer's own directory. Self-awarded badges score zero.

4

Warranty Strength — 20%

Published workmanship-warranty length. When a company's own materials disagree, we score the shortest published figure and say so in the review.

5

Experience — 10%

Years since the company's earliest verified activity in New Jersey: its first appearance in the state's solar program records or its contractor registration, whichever came first.

To be ranked, a company must have an active NJ contractor registration, meaningful volume in the state's solar program records, and an established review presence across major platforms. Some of the state's highest-volume installers aren't ranked because we could not independently confirm their records to the same standard, and we don't rank what we can't confirm.

Frequently Asked Questions

Is solar worth it in New Jersey?
For most owner-occupied homes with decent sun, yes. New Jersey residential electricity averaged 23.27¢ per kWh in May 2026, about 26% above the U.S. average, and the state pays a fixed $77 per SREC-II for 15 years on top of bill savings. Your exact payback depends on your roof, usage, and quote, so compare at least three bids.
What solar incentives are available in New Jersey?
Three main ones. The SuSI program's ADI pays residential systems $77 per SREC-II (one per megawatt-hour generated) for 15 years, the rate for registrations on or after July 27, 2026. Solar equipment is exempt from state sales tax, and the added home value from a certified system is exempt from property tax. The federal residential credit ended for cash and loan purchases after 2025; a lease or PPA provider may still monetize a federal credit and reflect it in your rate.
Who installs the most solar in New Jersey?
In the state's own program records, Trinity Solar leads with more than 12,000 installs under the current incentive program and over 24,000 under the legacy program that preceded it. SunnyMac Solar and Momentum Solar have each completed more than 7,000 current-program installs. Volume is only one factor in our rankings. See the methodology above.
How do I check a New Jersey solar company's license?
Search the company's name in New Jersey's state license lookup under "Home Improvement Contractors" and confirm the registration shows as Active. Solar installations also involve electrical work, so ask for the company's electrical contractor permit number and check it the same way under "Electrical Contractors." For disputes involving your utility or interconnection, NJBPU's Division of Customer Assistance takes complaints at (800) 624-0241.
How did EcoGen America choose these companies?
We check each installer against primary sources: the state contractor registry, NABCEP's directory, BBB records, manufacturer installer networks, and New Jersey's own program install data. Companies cannot pay for placement, and anything we cannot confirm at the source doesn't count toward a score. Full methodology above.
