Company overview
Founded in 1994 and still family-owned, Trinity Solar started as a heating and cooling company before becoming a dedicated solar installer. That longevity matters: many solar companies that sell systems subcontract the actual installation, but Trinity uses its own employees for most installs across its core Northeast territory. For homeowners, an in-house crew usually means clearer accountability if something goes wrong years later.
Trinity Solar cost & financing
Trinity does not publish fixed prices, because the cost of a solar system depends on your roof, energy use, and local incentives. In practice, residential systems in Trinity’s markets typically fall within the national range of roughly $2.50–$3.50 per watt before incentives, so a 7–8 kW system often lands in the five figures before the federal tax credit. Your actual quote can vary widely.
The more important factor is how you pay. Trinity offers four paths: buying with cash, financing with a solar loan, a lease, or a power purchase agreement (PPA). Cash and loans let you own the system and claim incentives; leases and PPAs lower upfront cost but reduce long-term savings and can complicate a future home sale. Ask Trinity to show side-by-side 25-year numbers for each option before deciding.
Equipment & warranties
Trinity installs mainstream, tier-one equipment, pairing high-efficiency panels with microinverter or string-inverter systems depending on the home. Coverage generally includes manufacturer equipment warranties (typically 25 years on panels) plus Trinity’s own workmanship warranty. Because warranty terms are where installers differ most, confirm in writing the length of the workmanship guarantee and whether a production guarantee is included.
Pros and cons
Pros
- Decades of experience and a large, established footprint in the Northeast.
- In-house installation crews rather than subcontractors in core markets.
- Full range of financing options, including ownership paths.

Cons

- Lease/PPA contracts can limit long-term savings if not carefully compared.
What customers say
Across independent platforms such as the Better Business Bureau, Google, and Trustpilot, Trinity Solar’s feedback is mixed but leans positive on installation quality. Recurring praise centers on professional install crews and systems that perform as expected. Recurring complaints tend to focus on the sales process, scheduling delays, and communication after the sale — issues that are common across the high-volume solar industry rather than unique to Trinity. As always, weight recent reviews from your own state most heavily.
Trinity Solar complaints and lawsuit questions
Many shoppers search for “Trinity Solar lawsuit” or “Trinity Solar complaints,” so it is worth addressing directly. Like most large solar companies, Trinity has accumulated formal complaints on the BBB and consumer forums, typically involving contract disputes, sales claims, or post-install service. We are not aware of a class-action outcome that defines the company, and complaint volume should always be read relative to the company’s very large installation count. The practical takeaway is the same regardless: read your contract carefully, confirm every savings claim in writing, and keep documentation of what your salesperson promised.

Against national lease-focused brands, Trinity stands out for its in-house installation and ownership options. If you are cross-shopping, it is worth comparing quotes from other large installers in our best solar companies guide to benchmark price per watt and warranty terms. The best installer is often the one that is transparent and local to your state.
