Your Home
Custom-designed residential solar systems built for Long Island rooftops, from North Shore colonials to South Fork cottages. We handle permits, utility interconnection with PSEG LI, and installation from start to finish.
Your Business
Reduce your operating costs with a commercial solar system designed around your energy use, your roof, and your Suffolk County location. Our PSEG LI relationships mean faster approvals and fewer delays.
New Construction
On-time, on-budget solar for builders and architects across Long Island. We work alongside your project team from design through certificate of occupancy, with zero surprises.
We Work Here. We Live Here.
GreenLogic has been designing and installing solar panels on Long Island for over two decades. We're local, rooted in Suffolk and Nassau counties, and we know the utilities, the municipalities, and the coastal conditions that make Long Island installations different from anywhere else.
We don't subcontract your install to a rotating crew. Every system is handled by our people, to our standards, because your system is our next referral.
Solar Incentives On Long Island
Suffolk and Nassau County residents still have access to incentives that meaningfully lower the cost of going solar. The federal residential credit has ended for new systems, but New York's state and utility programs remain strong. Current incentives include the New York State Solar Tax Credit of up to $5,000, PSEG LI Net Metering, a full property tax exemption on added value, and zero-down financing. Our energy consultants run the numbers against your actual roof and usage, so the figure you see reflects your home.
Award-Winning. NYSERDA-Certified.
GreenLogic holds NYSERDA Quality Solar Installer Gold Status, the state's highest mark for installation quality and customer satisfaction, along with multiple Excellence Awards and Trade Ally recognition from PSEG LI. That standing is earned, not bought, and it holds long after the panels are on the roof. It's why thousands of Suffolk and Nassau County homeowners and business owners trusted us with the job.

Long Island Solar FAQ
For most homeowners here, yes. The Island carries some of the highest electric rates in the country, so producing your own power starts paying off fast. Add state credits and utility programs on top, and a well-sized system usually earns back its cost long before the warranty is up. The honest answer comes down to your roof and your usage, which is exactly what a free consultation figures out.
It depends on the size of the array, your roof, and how much energy your household uses. Most residential projects land in a broad range before incentives, and the credits available can bring the net figure down considerably. We lay out the full picture in our guide to solar panel costs on Long Island, and a consultant can give you a real number for your address.
Quality panels are built to generate for decades, and most carry performance warranties of twenty-five years or more. The equipment we install is chosen for exactly that kind of longevity, so the system keeps working well after it has paid for itself. Inverters may need one swap over that span, and we plan for it up front so nothing catches you by surprise.
They can. Buyers across the region increasingly treat an owned array as a selling point, since it means lower energy bills from day one. Research has generally found that homes with a system sell for more than comparable homes without one. The important word is owned, which is why we walk you through how each financing choice affects resale before you decide anything.
We install hardware from top manufacturers, picked for output, durability, and how it looks on a roof. Every project is covered by manufacturer warranties on the panels and components, plus our own workmanship guarantee on the installation itself. After thousands of jobs across the Island, our service team spends more time in the office than out on callbacks, which tells you plenty about the gear we stand behind.

Solar Tax Credit 2026: How a PPA Still Captures the Federal Incentive for Long Island Homeowners
The rule that shaped rooftop solar for two decades quietly changed this year, and homeowners who buy their panels outright in 2026 no longer get the 30 percent federal tax credit. It didn't disappear though, it moved to the commercial side, and here's how a PPA still captures it for Long Island homeowners.
Do Solar Panels Affect Your Home Insurance? A Long Island Homeowner's Guide
Going solar raises a fair question before the first panel goes up: what happens to your home insurance? Here's what's covered when you own the system, what nudges your premium, and how a PPA shifts the panels onto the provider's policy instead of yours.
How PSEG LI Net Metering Works for Long Island Solar Homeowners
When your Long Island solar panels produce more than your home uses, PSEG LI credits your account at the retail rate. Here's how net metering works, what happens to unused credits at year-end, and how Time-of-Day rates change the math.

I had spoke with 3 or 4 different Solar Companies. In the end, I went with GreenLogic and it wasa great decision. I would recommend them to anyone interested in Solar!
GreenLogic installed my solar panels and they look beautiful. Everything is as they said! I am already seeing results in my PSEG Bill and love that I can track it. It has only been 2 months, but delighted with package and tax savings.
They not only were responsive and quick moving, but they found me more saving through state incentives! The workers did a great job and cleaned up after themselves. Overall very happy with them!
