Which SunPower is selling today?

According to EnergySage, SunPower Corporation filed for Chapter 11 bankruptcy on August 5, 2024. Complete Solaria bought Blue Raven Solar, the New Homes business and the dealer network in a $45 million deal that closed September 30, 2024. It rebranded as SunPower in April 2025 and changed its legal name to SunPower Inc. in October 2025. In September 2025 it acquired Sunder Energy, which EnergySage says expanded its installation footprint from 22 to 45 states.

SunPower Inc. issues its press releases from Orem, Utah. In its Q1 2026 results it reported record bookings of 4,446 jobs and named acquisitions including Sunder, Ambia and Cobalt.

SunPower Inc. says it did not take on systems installed before September 30, 2024. Owners of those systems should contact their lender (cash or loan) or their financier or SunStrong Management (lease or PPA). Our solar orphans hub explains next steps.

About Trinity Solar

EnergySage lists Trinity Solar's headquarters in Wall, NJ, with other offices in Connecticut, Massachusetts, New York, Maryland and Pennsylvania. The company began in 1994 and describes itself as family owned. EcoWatch says it started as a family-owned HVAC company and has served solar customers since the early 2000s.

Trinity's website has sections for solar, home batteries and EV chargers, and roofing, with separate solar and roofing payment options. EnergySage also lists energy auditing, electrical contracting, solar repair and maintenance, and community solar among its services.

Financing: direct options vs partner programs

SunPower's financing page lists four options:

• Cash for outright ownership.
• Loans with $0-down options through lending partners for qualified buyers.
• Leases where the provider installs, maintains and insures the system.
• PPAs where you pay only for the electricity the system produces.

SunPower notes that depending on your state, one third-party option may be available and the other not, and that savings are not guaranteed. In January 2026 it also announced a battery program using Palmetto's LightReach financing and Enphase IQ Battery 10C units, open to homeowners in the 45 states it serves, with priority access for existing SunPower customers.

Trinity's payment options page lists buying outright, a solar loan, or a lease or PPA where a third party owns the system. It says the loan, lease and PPA programs come from Trinity partners, not Trinity directly, and that they vary by state. EcoWatch's comparison lists only cash and loans for Trinity, so ask which programs apply at your address and who would own the system.

On tax credits, the IRS says the residential clean energy credit is not available for property placed in service after December 31, 2025. A purchase quote today should not subtract it. See solar savings without the federal tax credit.

SunPower vs Trinity Solar warranties

SunPower Inc.

• Two years of service coverage, with SunPower inspecting issues and coordinating eligible repairs at no cost.
• A 10-year workmanship warranty covering installation quality, waterproof roof penetrations and design-related issues.
• Manufacturer warranties on panels and microinverters lasting up to 25 years. After year two, SunPower assists with claims but you pay any manufacturer claim fees.
• A production guarantee: if output falls below 50% of projected output for 3 consecutive months, or below 85% for 18 consecutive months, SunPower adds panels or compensates you, subject to terms.

Trinity Solar

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

Trinity says coverage may vary by equipment, payment arrangement, signed agreement and installation date, and that your proposal documents control. EnergySage's profile mentions a minimum 5-year warranty against defects in materials and workmanship, so ask Trinity which terms apply to you. EcoWatch reports Trinity does not offer a production guarantee.

Where each company installs

Trinity's website lists Connecticut, Delaware, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Rhode Island and Ohio. SunPower's January 29, 2026 announcement said it serves 45 states. If you live in one of Trinity's states, you can likely get quotes from both. Elsewhere, SunPower may be the only one of the two available. Check your ZIP code with each.

Ask both companies whether your installation will be done by their own crew or a subcontractor, since that affects who handles workmanship issues later.

Questions to ask both before signing

1. What is the full cash price, and what is the financed price including all lender or dealer fees? The Consumer Financial Protection Bureau warns these fees are rarely disclosed.
2. Which exact panel, inverter and battery models are included, and where are their warranty documents?
3. Who handles service after the first two years (SunPower) or after installation (Trinity)?
4. Is the price shown without any federal residential tax credit?

Reviews and how to decide

On EnergySage in November 2026, Trinity Solar had a 3.7 rating from 71 reviews. EcoWatch reports an A+ rating with the Better Business Bureau. Because today's SunPower Inc. is a different company from the one many older reviews describe, read recent reviews carefully and check which company the reviewer actually dealt with.

Some practical ways to decide:

• You want a production guarantee. SunPower Inc. lists one; Trinity does not, per EcoWatch.
• You want clear, component-by-component purchase warranties. Trinity publishes them on its site.
• You want $0 down with no ownership. SunPower lists leases and PPAs on its own financing page; Trinity offers them through partners, so ask who the owner would be.
• You also need a roof. Trinity lists roofing as a business line.

The Federal Trade Commission suggests confirming that the contract matches what the salesperson promised, including payment increases, fees and who handles repairs.
