Momentum Solar review: if it’s been calling you, you’re not alone.

Momentum also uses the name Pro Custom Solar. It paid $20 million to $30 million to settle class actions over unwanted sales calls. A federal court gave final approval on August 18, 2025.

A class action is one lawsuit filed for a large group of people. These were filed by people who got sales calls they did not want. The cases were in federal court in New Jersey, where Momentum is based. Momentum denied doing wrong, which is common in a settlement. The court-appointed settlement office posts the official details online.

We count this against Momentum because it is about how the company sells solar. Our formula takes 10 points for a class-action settlement over sales in the last five years. It did not touch Momentum’s contract score. The case was about phone calls, not prices or contract terms.

Federal do-not-call rules apply to every telemarketer, including Momentum. Your rights depend on three things: the registry, your history with the company and whether you asked it to stop.

Two rules do most of the work. First, once your number has been on the National Do Not Call Registry for 31 days, most sales calls should stop. Second, once you tell a company not to call you, it has to stop. That is true even if you are already a customer. The FTC’s rules for telemarketers spell out both.

Momentum earned full marks for its own crews, its time in business and its BBB grade. The settlement, its warranty papers and no posted prices cost it the most.

Momentum missed 37 points. Price cost it 11. Contract terms cost it 12, mostly because its best warranty terms appear only in an out-of-state lease. The call settlement cost 10 more. The last 4 points went to a missing NABCEP credential, a top installer certification.

One formula for every company, public records only. Momentum doesn’t pay us, and ads never move a score.

Its state pages say so. But the only paper we found with the full terms is a lease filed in New York. It promises 25 years of workmanship and 95% of expected power.

That matters because your contract decides what you get, not a web page. A workmanship warranty covers the install work. A production guarantee is a promise about how much power you will make. The New York lease shows the promises Momentum made there. Terms can change from state to state. So our formula gives half credit until we can read them in a current contract from another state.

We also found no written roof-leak warranty. Leaks are the biggest worry with any roof install. Ask for one in writing, with the number of years.

Momentum says it does not hand installs to subcontractors. That earned it all 12 points for who installs.

A 2023 company post says, “We don’t use subcontractors for solar installations.” Nothing newer on its site says otherwise.

It is also in Enphase’s installer program at the Platinum level, the top tier for that equipment maker. That is worth 2 points in our formula. What it lacks is a NABCEP-certified installer on staff. That cost it 4.

Momentum answered all 30 of the newest complaints on its BBB file. Slow replies came up most. Repair and system problems came next.

We read the 30 newest complaints, from March 14 to September 5, 2026. Here is how often the top three problems came up:

• Slow or no response: calls went to a recording, and emails sat for weeks until the customer pushed harder.
• Warranty or repair service: one owner could not get a free new microinverter put in. The owner was told another installer would void the warranty.
• System not working: one system made no power for months in peak summer, and no repair date was set.

Complaints only lower a score in our formula when the BBB flags a pattern. Momentum’s file has no such flag. Read them anyway. They show what to get in writing.

Momentum posts no prices or loan fees. The only way to judge a quote is to compare it with companies that post theirs.

Momentum ofers cash, loans, leases and power-purchase plans, plus Enphase batteries. Whatever you pick, ask for three things on paper: the total price, the price per watt and every loan fee. Then compare. Our Tesla price estimator shows what your system size costs at each posted price.

If a rep takes a 30% federal tax credit off your price, stop there. That credit ended for buyers on December 31, 2025. Momentum’s current pages get this right. That earned it 4 points for honest tax-credit claims.

Momentum’s main list names seven states. Its Texas license is active.

These are the states it names:

• Connecticut
• Florida
• Massachusetts
• Nevada
• New Jersey
• New York
• Texas

In Texas, the state shows Momentum Solar, LLC under license EC-38847. It is active through February 8, 2027. That puts Momentum in our Texas ranking, tied for 16th of 20. One snag: its website footer lists a different Texas number, 31915. The state’s  search shows that number belongs to one electrician, not to the company. So when you check, search by the company name instead.

Its map shades more states than its list names. We count the seven it names.

Use these with the rep at your table, or on the phone if they called you first.

1. Can I see the warranty in my state’s contract? Make sure the 25 years of workmanship and the power promise are in your own agreement.
2. Is there a roof-leak warranty, and for how long? Get the number of years in writing.
3. What is the full price, per watt, with every loan fee? Compare it with companies that post prices.
4. Will you take me off your call list? If you don’t want more calls, say so. The company has to honor it.

Short, sourced answers about the company, the settlement and the calls.
