Financing: lease and PPA vs ownership

Momentum Solar's website lists four ways to pay: cash, a solar loan, a solar lease or a PPA. It explains that with a loan you own the panels, with a lease you make fixed monthly payments without owning them, and with a PPA you pay a set rate per kWh with no upfront cost. Momentum also says the solar agreement can transfer to a new owner if you sell your home.

Trinity's solar payment options page lists three paths: buying the system outright, a solar loan, or a lease or PPA in which a third party owns the system. Trinity says the lease, loan and PPA programs come from partner companies, not from Trinity directly, and that options vary by state. EcoWatch's comparison lists only cash and loans for Trinity, so ask which programs are offered at your address.

If you want no upfront cost and someone else to own and maintain the system, ask both companies for a lease or PPA quote and find out who the owner of the system would be. If you want to own the system, both companies offer that path. Our guide to solar lease vs buy walks through the trade-offs.

A note on tax credits: some installer pages still mention a 30% federal credit. The IRS says the residential clean energy credit is not available for property placed in service after December 31, 2025, so a system installed now should not be priced as if you will receive it.

Momentum Solar vs Trinity Solar warranties

Trinity Solar

Trinity's warranty page, for upfront solar purchases, lists:

• Solar panels: 25 years
• Inverters: up to 12 years
• Labor: 10 years
• Roof penetrations: 5 years

Trinity notes that coverage can vary by equipment, payment arrangement, signed agreement and installation date, and that the documents in your proposal control. EnergySage's profile describes a minimum 5-year warranty against defects in materials and workmanship, so ask Trinity which terms apply to your contract.

Momentum Solar

EcoWatch reports that Momentum provides the manufacturer's warranty, usually 10 to 25 years, plus its own 25-year equipment and workmanship warranty, and that coverage is the same regardless of payment method. Momentum's own website pages we reviewed did not state warranty terms, so get them in writing.

Which company fits your situation?

Neither company is the right answer for every home. These scenarios can help you narrow it down:

• You want $0 down and no maintenance duties. Momentum lists leases and PPAs. Trinity lists them through partner companies, so ask which partner would own the system.
• You want to own the system and see detailed warranty terms upfront. Trinity publishes its purchase warranty terms by component. Ask Momentum for its warranty document so you can compare line by line.
• You live outside the Northeast. Trinity's listed states are in the Mid-Atlantic, New England and Ohio. Momentum lists states such as Florida, Nevada and Texas.
• You also need a new roof. Trinity lists roofing as a service; ask Momentum whether it can handle roof work. Doing both at once can avoid paying later to remove and reinstall panels.

Questions to ask Momentum Solar and Trinity Solar before signing

The Federal Trade Commission suggests confirming that the written contract matches what the salesperson promised. Ask both companies:

1. What is the total cash price, and what is the price with financing, including any lender or dealer fees?
2. Which exact panel, inverter and battery models will you install?
3. How long is your workmanship warranty, and does it cover roof leaks at the mounting points?
4. Is there any production guarantee? If not, how will you respond if output falls short?
5. Who services the system if your company stops operating in my area?
6. For a lease or PPA: does the payment rise each year, and what are the buyout and transfer terms?

Then compare the answers in writing. A clear, specific written reply is a good sign; vague answers are a reason to slow down.
