To choose a good solar installer in New York, vet on facts, not the sales pitch. Confirm the company is a NY-Sun participating contractor, because NYSERDA pays its incentives only through approved contractors, check for a NABCEP-certified installer on staff and the right local home-improvement license, insist on a written workmanship warranty, and compare at least 3 detailed quotes before you sign.
By MySolarFY Editorial · Reviewed August 2026 · how we research and source these guides.
Picking the company matters as much as picking the panels. New York has one of the more generous incentive stacks in the country, but a lot of that value moves through the installer you hire, and the rules here are local and specific. This guide walks through how to evaluate, vet, and choose a solar installer in New York: the credentials that actually mean something, the New York specific requirements, the questions to ask, and the red flags that should end the conversation. It is a selection guide, not a ranking. We do not crown a winner or push one company over another, because the right installer depends on your roof, your budget, and who serves your address.
Why choosing the right installer matters more in New York
New York homeowners pay well above the national average for electricity, about 28.55 cents per kWh as of March 2026 (U.S. Energy Information Administration), so a well built system offsets an expensive bill for 25 years or more. But two things make installer choice especially high stakes in New York. First, the state’s up-front NY-Sun rebate is only paid through contractors NYSERDA has approved, so the wrong company can cost you a real incentive. Second, New York has no single statewide solar license, so the checks that protect you happen at the local level and vary by county and city. A homeowner who knows what to verify has a large advantage here.
How to vet a solar installer in New York: the checklist that matters
Every criterion below is something you can verify before you sign. Work through them with each company you talk to, and treat any that a salesperson dodges as a warning sign.
1. NY-Sun participating contractor status (New York specific)
This is the New York vetting point that generic checklists miss. NYSERDA’s own rule is direct: incentives are available only for new solar systems installed by participating contractors and builders (NYSERDA, How to Become a Participating Contractor). If a company is not an approved NY-Sun participating contractor, you cannot access the state’s up-front per-watt rebate through them. Ask the installer to confirm their NY-Sun participating status in writing, and ask whether they hold NYSERDA’s optional Quality Solar Installer (QSI) designation, which the state awards to contractors that exceed its annual quality-assurance criteria.
2. A NABCEP-certified installer on staff
NABCEP (the North American Board of Certified Energy Practitioners) issues the PV Installation Professional credential, the most recognized certification in residential solar across North America (NABCEP). It signals that the person designing or leading your install has passed a rigorous exam and met documented training and experience requirements. New York does not require it, so it is a differentiator: ask whether a NABCEP-certified professional will be involved in your system’s design and installation, not just listed on the website.
3. The right local license (New York has no statewide solar license)
New York State does not issue a statewide solar or contractor license. Instead, licensing is set locally by the authority having jurisdiction, so the requirement depends on where you live. New York City licenses home improvement contractors through the Department of Consumer and Worker Protection (NYC DCWP), and counties such as Nassau, Suffolk, Westchester, Rockland, and Putnam run their own home improvement contractor licensing (Nassau County, for example). Ask the installer for the specific local license that covers your address, then confirm it is current with that county or city office. Also confirm the electrical work will be pulled and inspected under the proper permit.
4. A written workmanship warranty
Panels and inverters carry their own manufacturer warranties, but those do not cover a bad install. A separate workmanship (labor) warranty covers the installer’s own work, including roof penetrations and leaks. Ask how many years it runs, get it in writing, and read what it excludes. A long, clearly written workmanship warranty is one of the better signals that a company expects to be around to honor it.
5. In-house crews vs subcontracted labor
Some companies install with their own employees, others subcontract the roof work to third-party crews. Neither is automatically wrong, but you should know which you are getting, because it affects accountability if something goes wrong later. Ask directly: will your own employees install my system, or a subcontractor, and who honors the workmanship warranty if it is subcontracted? Get the answer in writing on the contract.
New York installer vetting at a glance
Here is the short version of what to verify, why it protects you, and how to check it yourself.
| What to verify | Why it matters | How to check |
|---|---|---|
| NY-Sun participating contractor status | NYSERDA pays the up-front rebate only through approved contractors | Ask for it in writing; confirm with NYSERDA NY-Sun |
| NABCEP-certified installer on staff | The recognized proof of trained, tested PV expertise | Verify the credential at NABCEP |
| Local home improvement / electrical license | New York licenses at the county or city level, not statewide | Check your county or city office (for example NYC DCWP) |
| Written workmanship warranty | Covers the install itself, including roof leaks, beyond the equipment | Get the term and exclusions in writing before signing |
| In-house vs subcontracted crews | Determines who is accountable for the work and the warranty | Ask directly and confirm on the contract |
| Insurance and references | Protects you during and after the install | Ask for proof of insurance and recent local references |
A New York number to check quotes against. NY-Sun incentives recently ran about $0.15 to $0.20 per watt in the Con Edison and Upstate regions (NYSERDA, 2026). MySolarFY’s estimate (August 2026): at $0.20 per watt, a typical 8 kW system earns roughly $1,600 off the price before you compare quotes. The per-watt rate declines as regional blocks fill and Long Island residential blocks are closed, so confirm your region’s current figure with your installer.
| System size | NY-Sun offset at ~$0.20/W (est.) |
|---|---|
| 6 kW | about $1,200 |
| 8 kW | about $1,600 |
| 10 kW | about $2,000 |
MySolarFY estimate, August 2026. The NY-Sun rebate is an up-front price reduction, separate from the bill savings you get from offsetting power at about 28.55 cents per kWh. Actual per-watt rates decline as blocks fill and vary by region, so treat these as a sanity-check on a quote, not a guarantee.
Questions to ask a New York solar installer before you sign
MySolarFY’s review of New York installer vetting (August 2026) settled on 9 questions that separate a solid local contractor from a sales operation, and we advise walking away from any written workmanship warranty under 10 years. Bring this list to every consultation.
- Are you a NY-Sun participating contractor, and can you confirm it in writing?
- Do you hold NYSERDA’s Quality Solar Installer (QSI) designation?
- Will a NABCEP-certified professional design and oversee my installation?
- Which local home improvement or electrical license covers my address, and is it current?
- Will your own employees install my system, or a subcontractor?
- How many years is your written workmanship warranty, and what does it exclude?
- Can you show proof of insurance and recent references near me?
- What are the real, itemized numbers on this quote, in dollars, with no rebate assumed until confirmed?
- If this is a lease or PPA, what is the total cost over the full term, not just the monthly payment?

Red flags: when to walk away from a New York solar company
Vetting is as much about spotting bad actors as confirming good ones. These are the patterns that should end a conversation:
- High-pressure “sign today” sales. A real installer will let you compare quotes and read the contract. A “this price is only good tonight” close is a pressure tactic, not a deal.
- Free-solar promises. Any pitch that promises free solar panels is a red flag, because solar panels are not free and a lease or PPA is a financing arrangement, not a giveaway. Read the total cost over the full term before you sign.
- Unrealistic savings promises. Be skeptical of guaranteed savings figures, “eliminate your bill forever,” or numbers that do not show their math. Your actual savings depend on your roof, your usage, and your rate, and no honest company can promise an exact number up front.
- Vague credentials. If a company will not confirm its NY-Sun participating status, its license for your area, or who actually installs the system, treat that as your answer.
A quick way to read any consultation:
| Green flags (good signs) | Red flags (walk away) |
|---|---|
| Confirms NY-Sun participating status in writing | Dodges NY-Sun status or local licensing questions |
| A NABCEP-certified pro on the actual project | High-pressure, sign-tonight deadline |
| Written workmanship warranty of 10 years or more | A giveaway pitch or guaranteed savings promise |
| Itemized quote, no rebate assumed until confirmed | Quote built on the federal credit that ended after 2025 |
What about the federal tax credit?
Do not let a salesperson build your quote around the old 30% federal credit. The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, so a homeowner installing in 2026 cannot claim that 30% federal credit (IRS, Residential Clean Energy Credit). If a New York installer’s savings math still assumes it, that is a reason to slow down. New York’s own incentives, including the NY-Sun rebate and the state’s separate equipment credit, are what carry the value now. See our New York NY-Sun incentive guide for 2026 for what actually applies. MySolarFY does not give tax advice; confirm your own situation with a tax professional.

Frequently asked questions
How do I know if a solar installer is legitimate in New York?
Verify a short list of facts rather than trusting the sales pitch. Confirm the company is a NY-Sun participating contractor, since NYSERDA pays its incentives only through approved contractors (NYSERDA). Check that a NABCEP-certified professional is involved, confirm the local home improvement or electrical license for your address, and get a written workmanship warranty and proof of insurance. Then compare at least three itemized quotes. A legitimate installer will answer all of these in writing without pressure.
Do I have to use a NY-Sun participating contractor?
If you want the state’s up-front NY-Sun rebate, yes. NYSERDA states that its incentives are available only for new solar systems installed by participating contractors and builders (NYSERDA). You can technically hire a non-participating company, but you would give up that rebate, which is real money in most regions. Always ask a New York installer to confirm their participating status in writing before you sign.
Is NABCEP certification required to install solar in New York?
No, New York does not require NABCEP certification, which is exactly why it is a useful differentiator. The NABCEP PV Installation Professional credential is the most recognized certification in North American residential solar (NABCEP). Ask whether a NABCEP-certified professional will actually design and oversee your installation, not just appear on the company’s marketing.
Does New York require a state solar contractor license?
New York State does not issue a single statewide solar or contractor license. Licensing is handled locally, so the requirement depends on your county or city. New York City licenses home improvement contractors through its Department of Consumer and Worker Protection (NYC DCWP), and counties like Nassau run their own licensing (Nassau County). Ask the installer for the license that covers your address and confirm it is current with that local office.
Has the 30% federal solar tax credit ended for 2026?
Yes. The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, so a homeowner who installs solar in 2026 cannot claim that 30% federal credit (IRS). Be wary of any New York installer whose savings math still assumes it. New York’s NY-Sun rebate and state incentives are what carry the value now. MySolarFY does not provide tax advice; confirm your situation with a tax professional.
Is a “pay nothing upfront” solar offer the same as free?
No. A pitch that promises free solar panels is a red flag, because solar panels are not free. A lease or PPA is a financing arrangement where a third party owns the system and you pay for the power or the equipment over time. Some homeowners qualify for zero-up-front financing where available, but that is not the same as a giveaway. Always read the total cost over the full term before you sign.
MySolarFY is a free service that matches homeowners with licensed local solar installers. We are not a solar installer, a financing company, or a tax advisor, and this guide describes how to evaluate installers on objective criteria. We do not crown a single winner, because the right installer for you depends on your home. A lease or PPA may carry an annual escalator and can cost more than paying cash over the full term, and because the 30% federal credit ended after December 31, 2025, no financing arrangement can pass that credit through to you. Figures are dated and sourced; confirm incentives and licensing for your address, and your own tax situation with a professional, before you sign.
