Trinity Solar: What to Check Before You Sign
Trinity Solar is one of the larger installers operating in the Northeast, and it comes up often in New York. We have no proprietary data on them, so here is how to assess them properly instead.
Trinity Solar is a large family-owned installer operating across the Northeast including New York. To evaluate them, verify NYSERDA participating contractor status and NABCEP certification, establish whether you are being offered a purchase or a lease, and read third party reviews on Google, the BBB and EnergySage.
What is publicly known
Trinity Solar is a long-established, family-owned solar installer operating across several Northeastern states including New York. It is among the larger residential installers in the region by volume.
Beyond that, we are not going to characterise their service quality, because we have no basis to. What we can do is tell you what to check.
Verify these four things
NABCEP directory
Check whether the individuals doing your installation hold the industry standard credential. NABCEP certifies people, not companies, which is worth knowing when a company advertises it.
NYSERDA participating contractor list
In New York this is not optional. The NY-Sun rebate is only available through an approved contractor, and the state tax credit is calculated after that rebate.
Your state licensing board
Verify electrical licensing, and ask for current certificates of general liability and workers compensation insurance before work starts.
Third party review platforms
Google, the Better Business Bureau and EnergySage carry real customer reviews. Read the negative ones and look at how the company responded.
Establish the structure first
Before comparing any numbers, establish whether you are being offered a cash purchase, a loan, a lease or a power purchase agreement. Large installers typically offer several, and the quotes are not directly comparable.
This matters more than it used to. Since the federal residential credit ended for systems installed after 31 December 2025, a lease or PPA is the only route by which a homeowner reaches a federal incentive, because the owner claims it and reflects it in your rate.
Questions worth asking
- Is this a purchase, a loan, a lease or a power purchase agreement? The answer changes everything else.
- If financed, what is the dealer fee, and what is the cash price of the identical system?
- If leased or a PPA, what is the annual escalator and what does the payment look like in year 20?
- Who actually performs the installation, the company or a subcontractor?
- What does the workmanship warranty cover, for how long, and who honours it?
- What production is guaranteed, and what happens if the system underperforms?
- Is a service upgrade included or excluded from this price?
- How does the agreement transfer if I sell the house?
Questions people ask about this
We are not in a position to rate them and we would not trust a rating from any site earning referral fees, ours included. Check their NYSERDA participating contractor status, NABCEP certification, and read recent third party reviews on Google, the BBB and EnergySage, paying attention to how they respond to complaints.
They operate across several Northeastern states including New York. Coverage of specific counties is worth confirming directly, as installer service areas change.
Always, from any company. Two or three quotes shows you the range. Compare net cost per watt rather than headline totals, and check what each includes, particularly whether an electrical service upgrade is in or out.
The annual escalator and what the payment looks like in year 20, the transfer terms if you sell, who is responsible for maintenance and inverter replacement, and whether there is a buyout option and how its price is determined.
How to check any solar contractor
This is a new site with no customer reviews, so we are not going to show you any. What we can do is tell you exactly what to verify about whoever contacts you, and where to look it up. That applies to the installer we refer you to and to every other quote you get.
NABCEP certification
The North American Board of Certified Energy Practitioners is the industry standard credential for solar installers. It certifies the individual professional who holds it, not the company, so a firm advertising it may have one certified person and twenty who are not.
How to check. Ask which named individual holds it, then search that name in the directory.
Search the NABCEP directoryNYSERDA participation
Registration in the state's NY-Sun programme. This one is not a nice to have: the New York State incentive is only available through an approved contractor, so using an unregistered installer forfeits it. Some also hold the Quality Solar Installer designation, which requires at least 12 NY-Sun projects in the past year and an average of 4 out of 5 on NYSERDA's own field inspections.
How to check. Search the company name in NYSERDA's list before you sign anything.
Check NYSERDA's contractor listLicensing and insurance
Appropriate electrical licensing for the work, plus general liability and workers compensation cover. A contractor without workers compensation can leave you personally exposed if someone is injured on your roof.
How to check. Ask for certificates of insurance naming you, and check the licence with your town or county before work starts. Do not accept a policy number alone.
Local experience
Interconnection is where most New York solar timelines slip, and it is handled very differently by Con Edison, National Grid, NYSEG, RG&E and PSEG Long Island. Permitting varies again by town.
How to check. Ask how many systems they have energised on your specific utility in the past year, and for two addresses in your county you can drive past.
NY Solar Finder is operated by RBR Growth Consulting. We are not a solar installer, we hold no industry certification, and we do not guarantee the credentials of the company that contacts you. We name these standards, and link to the bodies that issue them, so that you can check that company yourself before you sign anything.
