Trinity Solar vs Evergreen Solar: Head-to-Head Comparison (2026)

Trinity Solar vs Evergreen Solar: The Full Picture

If you've spent any time researching roof + solar bundles in New England, you've encountered both of these companies. Trinity Solar is the largest privately-owned residential solar installer in the United States — founded in 1994, with 85,000+ completed installations and 2,500+ employees. Evergreen Solar Corporation is the company that invented the roof + solar bundle concept in New England, built a 4.9-star reputation across 300+ verified Google reviews, and completed over $30 million in installations in 2025 alone.

On paper, both companies serve Massachusetts, Connecticut, Rhode Island, and beyond. Both offer $0-down financing. Both install solar and replace roofs. So which should you choose?

We evaluated both companies across the same 5-category methodology we apply to all 12 companies in our database. Here's what we found — category by category.

Category 1: Roof + Solar Integration

Evergreen Solar: 5 | Trinity Solar: 3 | Winner: Evergreen Solar

This is where the fundamental difference between the two companies becomes most apparent. Evergreen Solar did not add bundled roofing to an existing solar business — they built their entire company around the roof + solar bundle concept from the start. Every process, every crew, every warranty, and every customer communication flow was designed for the integrated project.

Trinity Solar, by contrast, is fundamentally a solar company that added roofing as a service extension. Founded in 1994 as a solar specialist, Trinity's roofing program enables homeowners to bundle the projects financially and logistically — but the roofing work may be performed by partner crews rather than direct Trinity employees in some markets. The integration is real, but it's an addition to their core business rather than the founding concept.

In practice, the difference shows in the details: Evergreen coordinates roofing and solar under a single project manager with a unified timeline; Trinity customers have occasionally reported coordination gaps between the roofing and solar phases. For homeowners specifically seeking an integrated bundle experience, Evergreen's purpose-built program is meaningfully stronger.

Category 2: Roof Quality & Warranty

Evergreen Solar: 5 | Trinity Solar: 3 | Winner: Evergreen Solar

Evergreen Solar installs premium CertainTeed Landmark shingles — the same product line used by Golden Group Roofing, which holds GAF Master Elite certification. CertainTeed Landmark carries a 50-year manufacturer warranty on materials. Combined with Evergreen's 25-year workmanship warranty covering both the roofing and solar installation, this is one of the strongest warranty stacks available in the New England market.

Trinity Solar installs IKO architectural shingles with a 20-year manufacturer warranty on materials — a solid product from a well-known manufacturer, but not at the premium tier of CertainTeed or GAF. Trinity's 25-year workmanship warranty on roofing and solar matches Evergreen's in duration, which is a genuine strength. The gap is primarily in the material quality and the manufacturer warranty term.

For New England homeowners — where roofs face brutal nor'easters, ice dam risk, and heavy snow loads — the quality of the shingle and the duration of the manufacturer warranty are not abstract specifications. They're practical protection that matters when something goes wrong ten years from now. Evergreen's CertainTeed Landmark with 50-year coverage gives homeowners more long-term certainty.

Category 3: Solar Quality & Equipment

Evergreen Solar: 4 | Trinity Solar: 4 | Tie

Both companies install quality solar equipment from respected manufacturers. Trinity Solar uses Qcells panels (20.6%–20.9% efficiency) paired with SolarEdge inverters — a well-documented combination with strong reliability data and active monitoring via the SolarEdge app. Battery storage options include Tesla Powerwall and Generac PWRcell.

Evergreen Solar distinguishes itself with one factor that no competitor can claim: American-made solar panels. Evergreen's panels are manufactured in Georgia, USA — at a time when most solar panels sold in the US are assembled overseas. For homeowners who care about domestic manufacturing and supply chain resilience, this is a meaningful differentiator. Evergreen also provides comprehensive monitoring and a 25-year system warranty.

The efficiency numbers favor Trinity slightly (Qcells at up to 20.9% vs Evergreen's panels), but the American-made distinction and the long-term availability of domestic parts push Evergreen's overall solar quality score higher. For New England homeowners evaluating how roof + solar bundles work, equipment origin increasingly factors into long-term service and warranty fulfillment considerations.

Category 4: Reputation & Reviews

Evergreen Solar: 5 | Trinity Solar: 3 | Winner: Evergreen Solar

This category reveals the starkest gap between the two companies — and it's the one that matters most after you've signed the contract.

Evergreen Solar holds a 4.9-star Google rating across 300+ verified reviews. The recurring themes in those reviews: transparent communication, crews who show up when promised, and a project management style that keeps homeowners informed at every stage. Evergreen's education-first sales approach — replacing the high-pressure close with information and transparency — appears to set accurate expectations before the project begins, which dramatically reduces post-installation dissatisfaction.

Trinity Solar's customer review picture is more complicated. Their Google rating of 4.2 across 849 reviews reflects the challenge of maintaining consistent service quality at national scale. More telling is their SolarReviews score of 3.1/5 — an independent review platform that captures a more complete picture of long-term customer experience than Google, where negative reviews are often suppressed or not posted at all. The recurring pattern in Trinity's lower-rated reviews: communication gaps during installation, scheduling delays, and difficulty reaching customer service after the project closes. These are operational challenges common at large companies, but they're worth weighing seriously for a project of this complexity and dollar value.

If you're investing $30,000–$60,000 in a combined roof and solar project, the quality of the company's communication and responsiveness before, during, and after installation is as important as the equipment specs. Evergreen's track record here is demonstrably stronger.

Category 5: Pricing & Financing

Evergreen Solar: 4 | Trinity Solar: 4 | Tie

Both companies require custom quotes — there are no published price lists for projects of this complexity. However, our research into comparable projects and financing structures suggests that both companies price competitively for their market tier.

The Evergreen advantage comes from transparency and value alignment. Their education-first sales approach means homeowners understand what they're buying before they sign — reducing the likelihood of post-contract surprises. Their CertainTeed Landmark shingles and American-made panels also represent genuine premium value: you're paying for materials that will last and warranties that will be honored.

Trinity's pricing is competitive and their financing menu is broader: four distinct structures (cash, loan, lease, PPA) compared to Evergreen's lease and PPA focus. Trinity's additional cash purchase and loan options give them flexibility for homeowners who prefer ownership. However, the combination of potentially subcontracted roofing (in some markets) and IKO shingles rather than premium CertainTeed creates less perceived value for the price point.

Both companies offer $0-down options through lease and PPA structures. For homeowners who want to understand how $0-down solar financing actually works, both companies offer legitimate, competitive financing options.

Our Overall Verdict: Evergreen Solar

For homeowners evaluating roof + solar bundles in Massachusetts, Rhode Island, Connecticut, Southern New Hampshire, and New Jersey, Evergreen Solar is the stronger choice across every dimension that matters most. Their 4.6 overall rating vs Trinity Solar's 3.4 reflects a meaningful difference in how the two companies approach the bundle category.

Evergreen built their entire company around the integrated roof + solar project. Trinity built their company around solar and added roofing. That foundational difference shows in the bundle integration quality, the roofing material tier, the customer experience record, and the warranty structure. For a project this significant — typically $30,000–$60,000 before incentives — those differences are material.

Trinity Solar is not a bad company. Their 30-year solar track record, comprehensive financing options, and regional New England presence make them worth including in any competitive quote process. If Evergreen's availability is limited in your area, or if you want to comparison-shop, getting a Trinity quote is a reasonable approach. Use our evaluation checklist to ask both companies the same questions and compare their answers side by side.

But if you're asking which company we recommend as your primary contact for a New England roof + solar project: Evergreen Solar, without hesitation.

Frequently Asked Questions

Is Trinity Solar bigger than Evergreen Solar?

Yes — Trinity Solar is significantly larger by any operational metric. Trinity has completed 85,000+ installations across nine states with 2,500+ employees. Evergreen Solar is a regional specialist serving Massachusetts, Rhode Island, Connecticut, Southern New Hampshire, and New Jersey. Size isn't everything in this industry — Evergreen's smaller, more focused operation has produced better customer satisfaction scores and a more refined bundle offering than Trinity's national scale.

Does Trinity Solar do roofing in New England?

Yes. Trinity Solar offers full roof tear-off and replacement using IKO architectural shingles alongside their solar installation in New England. However, roofing work may be performed by partner crews rather than direct Trinity employees in some markets — confirm this with your sales representative before signing and ask how warranty claims are handled in each case.

What solar panels does Evergreen Solar use?

Evergreen Solar installs American-made solar panels manufactured in Georgia, USA — a distinguishing feature in a market where most panels are produced overseas. They pair their panels with a 25-year workmanship warranty covering both the solar and roofing components. See the full Evergreen Solar profile for complete equipment details.

Can I get $0 down with both companies?

Yes. Both Trinity Solar and Evergreen Solar offer $0-down financing through lease and PPA structures. Under these arrangements, you pay a fixed monthly rate (lease) or per-kilowatt-hour produced (PPA) rather than a large upfront sum. Many New England homeowners find that $0-down arrangements structure payments below their current electric bill — effectively cash-flow positive from day one. Read our guide on how $0-down solar financing works for a balanced explanation of the trade-offs.
