Momentum Solar Reviews (2026): Is It Legit, and Does It Serve California?

Momentum Solar is a legitimate, operating company, but it probably is not an option for a California home. Its own homepage, checked on September 23, 2026, lists seven service states and California is not one of them. Its Better Business Bureau file shows an A+ rating alongside 561 complaints in three years, most of them about service and repairs.

This review sets out what the company publishes about itself, what the BBB complaint file and the federal court record show, and what a California homeowner should check if a Momentum representative calls. It does not rate or rank the company.

Is Momentum Solar legit?

Yes, in the sense that matters first: it is a real business with a public track record.

The BBB profile for Momentum Solar in South Plainfield, New Jersey, shows an A+ rating, accreditation since March 24, 2015 and a business start date of November 1, 2009. bbb.org·checked Sep 23, 2026 Federal court captions name the company’s legal entity as Pro Custom Solar LLC, doing business as Momentum Solar, which is the name to look for on a contract. courtlistener.com·checked Sep 23, 2026

“Legit” is a lower bar than “good fit.” The rest of this page covers the two things that decide fit for a California reader: whether the company works here at all, and what its customers most often complain about.

Does Momentum Solar serve California?

Momentum’s homepage names its service states as “CT, FL, MA, NV, NJ, NY, and TX.” California does not appear anywhere on that page. momentumsolar.com·checked Sep 23, 2026 A list on a marketing page is not a legal statement, so the safest reading is simple: confirm your ZIP code with the company in writing before you spend time on a proposal.

The state’s interconnection record shows how that has changed. In the CPUC’s data for PG&E, SCE and SDG&E territory, residential systems listed under the Momentum Solar or Pro Custom Solar name were approved 217 times in 2024, 29 times in 2025 and not at all from January through May 2026, the latest month in the data set. Municipal utilities such as LADWP and SMUD are not in that data. californiadgstats.ca.gov·checked Sep 24, 2026

The court record shows some California connection in the past. Three federal cases naming the company were filed in California courts: Amini v. Pro Custom Solar LLC in the Central District (No. 8:17-cv-02243, filed December 26, 2017, closed January 3, 2018), Gordon v. Momentum Solar, LLC in the Southern District (No. 3:24-cv-00693, filed April 17, 2024) and Velasco v. Momentum Solar, LLC in the Central District (No. 2:25-cv-00016, filed January 2, 2025, closed February 25, 2025). courtlistener.com·checked Sep 23, 2026 courtlistener.com·checked Sep 23, 2026 A case filed in California can follow a call or text received here; it does not show the company installs here today.

Momentum Solar complaints: what the BBB file shows

On September 23, 2026, the BBB listed 561 complaints about Momentum Solar in the last three years and 184 closed in the last 12 months. By type: 254 service or repair issues, 113 sales and advertising issues, 71 product issues, 64 order issues, 26 billing issues, 26 customer service issues and 7 delivery issues. bbb.org·checked Sep 23, 2026

The recent complaints we read share a pattern. Customers describe waiting weeks or months for a technician after a system stopped producing, paying higher utility bills while it was offline, damage they attribute to the installation, and projects left with unfinished inspections or missing labels.

A BBB complaint is one customer’s account plus the company’s response, not a finding, and the count is not adjusted for how many systems the company installs.

Use the themes as questions: how fast is a repair visit scheduled in your area, who pays for roof damage traced to the install, and what happens to your payments while the system is down.

Is Momentum Solar a scam?

We found no primary source that calls it one. What the federal record does show is a run of lawsuits.

A party-name search on CourtListener returned 23 federal dockets; some list the company in roles other than defendant, and not every entry is about solar sales. courtlistener.com·checked Sep 23, 2026 Several are coded under the Telephone Consumer Protection Act, the federal law on marketing calls and texts, including Oguekwe v. Momentum Solar (D.N.J., filed December 18, 2025) and Murphy v. Momentum Solar (S.D. Fla., filed August 22, 2025, closed May 14, 2026). courtlistener.com·checked Sep 23, 2026 courtlistener.com·checked Sep 23, 2026 A related group of Whitten v. Momentum Solar matters appears before the Judicial Panel on Multidistrict Litigation. courtlistener.com·checked Sep 23, 2026 Others are employment and contract cases, and two new dockets were filed in April 2026.

A filed complaint is an allegation, and a closed docket does not say who won. The practical lesson does not depend on the outcome: if a solar company reaches you through a call or text you did not ask for, verify it more carefully, not less.

Is Momentum Solar a pyramid scheme?

No court case or company record we checked describes it as one. The Federal Trade Commission draws the line by where the money comes from: in a pyramid scheme, “your income would be based mostly on how many people you recruit, not how much product you sell,” while a legitimate business pays “based on your sales to retail customers.” consumer.ftc.gov·checked Sep 23, 2026

Momentum’s own careers page describes its sales jobs as base pay plus uncapped commissions and bonuses, meeting homeowners one to three times a day, five days a week, working company leads as well as referrals, with full benefits (medical, dental and 401K) and two weeks of instructor-led training.

It says nothing about pay for recruiting other salespeople. momentumsolar.com·checked Sep 23, 2026 That is the company’s account of the job, not an audit of how any representative is actually paid.

A CourtListener search on September 23, 2026 for “Momentum Solar” or its legal name, Pro Custom Solar, together with “pyramid” returned no case making that claim; the only opinion it found used the word as part of an unrelated case name. courtlistener.com·checked Sep 23, 2026 The dockets that do name the company include the marketing-call cases above and wage-and-hour cases under the Fair Labor Standards Act, such as Munoz v. Pro Custom Solar (E.D.N.Y., filed July 11, 2023, closed September 26, 2024), Tapia v. Pro Custom Solar LLC (E.D.N.Y., filed September 8, 2020) and Greer v. Pro Custom Solar LLC (M.D. Fla., filed May 8, 2020). courtlistener.com·checked Sep 23, 2026 courtlistener.com·checked Sep 23, 2026 courtlistener.com·checked Sep 23, 2026 The BBB file counts 113 sales and advertising complaints among the 561 in three years. bbb.org·checked Sep 23, 2026 None of these is a finding against the company.

They tell you what to ask a representative: who employs them, how the price was set, and whether anything they said is in the contract. Our guide to door-to-door solar sales in California covers your rights when a salesperson comes to the house.

Equipment, warranty and financing

Momentum’s homepage refers to battery storage and financing but names no panel, inverter or battery brand and states no warranty length. momentumsolar.com·checked Sep 23, 2026 That means the proposal has to supply all of it. Ask for the module, inverter and battery make and model, the workmanship warranty in years, and the financing agreement as a separate document from the installation contract.

Tesla Solar vs Momentum Solar in California

For a California home this is not a like-for-like choice.

Momentum’s homepage lists seven service states and California is not one of them, momentumsolar.com·checked Sep 23, 2026 while Tesla lists two California contractor licenses, CSLB 888104 and 1127593, and quotes by address through its online design tool. tesla.com·checked Sep 23, 2026 tesla.com·checked Sep 23, 2026 If you were weighing the two, put Tesla’s written quote beside one from another company that lists California.

Momentum Solar compared with ADT Solar and Trinity Solar

Searches often pair Momentum with two other East Coast names, and neither pairing is a choice a California homeowner can make. ADT announced on January 24, 2024 that it would exit its residential solar business, saying the exit “may include the transfer of components of the business to other parties.” investor.adt.com·checked Sep 24, 2026 In the CPUC’s data, ADT Solar had 1,398 residential systems approved in PG&E and SCE territory, the last 3 in 2025. californiadgstats.ca.gov·checked Sep 24, 2026

If you own an ADT Solar system, ask ADT in writing for your contract, warranty and monitoring records, and who, if anyone, took over your agreement. Panel, inverter and battery warranties come from their manufacturers. What to do when an installer is gone is in when your solar installer goes out of business.

Trinity Solar lists nine eastern states and no California, and no residential system under its name appears in the CPUC data since 2016; its review has the details. For a company that does sell in California, start with the Sunrun review or the California solar company reviews.

CSLB license: expired

The license number reported for Momentum Solar LLC on utility interconnection applications in California DG Stats (CPUC), data through May 31, 2026, is #1026366. On CSLB’s license lookup (checked September 24, 2026), that license belongs to Momentum Solar LLC in Orange, California, and it expired on May 31, 2025; CSLB says the license is not able to contract at this time. An earlier version of this page cited #997872; CSLB shows that number belongs to an unrelated painting company.

If anyone offers you a Momentum contract in California, check the license number on it at CSLB and confirm that the entity name matches the one on your contract. Our contractor-verification walkthrough shows where to look.

Questions to ask before you rely on any quote:

• Do you install in my ZIP code in California today, confirmed in writing?
• What legal entity signs my contract, and which California license number belongs to it?
• If you do not serve my area, which licensed California contractor would do the work?
• What are the panel, inverter and battery models, and the workmanship warranty in years?
