Who this guide applies to
This guide is for homeowners who bought solar from Momentum Solar, the trade name of Pro Custom Solar LLC. Momentum was founded in New Jersey in 2009, is based in South Plainfield, and has expanded to other states including New York, South Carolina, and Texas.
Momentum is operating and services its own installations. If you financed your system, your loan or lease is with the finance company named in your contract, which bills you directly.
If you signed recently
Act fast. For most sales made at your home, the federal Cooling-Off Rule gives you until midnight of the third business day after the sale to cancel. Many states give you more time or add rules for solar sales. New Jersey, for example, requires a three-day cancellation notice in home improvement contracts. Check your state on our state solar laws page.
Cancel in writing to the address in your contract, and send a copy to the finance company. Keep proof of when you sent it. Our cancellation letter builder can help.
Were you misled about your solar?
Tell us what happened. It takes about two minutes, and you decide what happens next.
See my optionsAfter installation
Once the window has closed and the system is installed, you usually can’t simply cancel. Your options depend on what you signed:
- Solar loan: you own the system. You can usually pay off the loan early. Ask the lender for a payoff letter and use our payoff calculator.
- Lease or PPA: the finance company owns the system. Ask it for a buyout or prepayment quote, or transfer the agreement when you sell.
- Cash: you own the system outright, and your issues are about warranty and workmanship.
For a home sale, see selling a house with a solar loan.
Service and warranty problems
Because Momentum is still operating, send service and warranty requests to the company first, and keep a written record of every request and response. Panel and inverter warranties are with the equipment manufacturers.
If a roof leak or system problem goes unresolved, the contractor licensing agency in your state can take a complaint about the work. In New Jersey, that is the Division of Consumer Affairs.
What we found about Momentum Solar
We did not find any state or federal enforcement action against Momentum Solar as of November 2026. In April 2025, Momentum agreed to pay up to $30 million to settle two private class action lawsuits alleging robocalls that violated the Telephone Consumer Protection Act. That was a private settlement, not a government action, and it was about calls, not contracts.
If you were misled
If you were promised savings you aren’t getting, a tax credit you didn’t qualify for, or a price lower than your loan shows, write down what you were told and gather your paperwork. Complain to Momentum and the finance company in writing first. If that fails, file with your state attorney general, and with the CFPB for loan problems.

Common questions
Is Momentum Solar still in business?
Yes. Momentum Solar is operating and services its own installations.
Can I cancel my Momentum Solar contract?
Within the cancellation window, usually yes, by sending written notice. After installation, you’d usually pay off the loan, buy out or prepay a lease, or transfer the agreement when you sell.
Who do I pay for my Momentum Solar system?
The finance company named in your contract, which bills you directly. Momentum doesn’t hold most customer loans or leases.
Has Momentum Solar been sued?
It settled two private robocall class actions for up to $30 million in 2025. We found no government enforcement action against it.
