Long Island's Home Solar Experts. Since 2005.
From Cold Spring Harbor and Huntington to Southampton and East Hampton, GreenLogic has installed residential solar panels on thousands of Long Island homes across Suffolk and Nassau counties. We know the local utilities, the local permits, and the local conditions so your installation runs smoothly from day one.
Long Island electric rates consistently rank among the highest in the United States. PSEG LI customers pay roughly twice the national average, and that gap widens every year. Solar doesn't eliminate your connection to the grid. It just dramatically reduces what you owe each month. With 200+ sunny days per year across Suffolk and Nassau counties, Long Island is one of the most productive solar environments in the Northeast. With PSEG LI's net metering program, any power you generate beyond your immediate needs earns you bill credits for later.
We're Not a National Company. We're Your Neighbors.
GreenLogic was founded on Long Island in 2005, and we've never expanded beyond it. Our team lives here, in Suffolk and Nassau counties. We understand how municipalities work, how utilities think, and what kinds of systems hold up through 40 years of coastal weather on the Sound and the Atlantic.
Local Offices.
Local Crew.
We have offices in Southampton, Manorville, and Roslyn Heights. Our own certified crew performs every installation with no subcontracting ever.
Direct Utility Relationships.
We maintain direct relationships with every Long Island municipality and PSEG LI, built over two decades of residential solar installations across Suffolk and Nassau counties.
Support for Life. Not Just Warranty.
We use proprietary performance tracking tools developed in-house and provide post-installation support for the full life of your system, not just the warranty period.
Know Your Incentives. Get the Full Picture.
GreenLogic energy consultants help you understand and claim every incentive available to you as a Suffolk or Nassau County homeowner. The New York State Solar Tax Credit covers up to $5,000. PSEG LI Net Metering credits your account for excess generation. Your solar added value is fully exempt from property tax. No generic estimates. We calculate your specific situation.
What Homeowners Ask Us Most
The questions Suffolk and Nassau County homeowners ask before making the switch to residential solar panels.
What exactly is changing with the federal solar tax credit?
The 30% Residential Clean Energy Credit will expire after December 31, 2025. To qualify, your system must be fully installed and approved for operation (PTO) by that date. There will be no step-down or extension — the credit will drop from 30% to 0% overnight.
What solar incentives are still available to Long Island homeowners in 2026?
The federal residential solar tax credit is no longer available for new homeowner-owned installations. However, Long Island homeowners still have meaningful incentives. The New York State Solar Tax Credit covers up to $5,000. PSEG LI Net Metering credits your account for any excess power your system sends to the grid. Your solar added value is fully exempt from property tax assessment under New York State law. Zero-down and low-rate solar loan financing is also available, meaning many Suffolk and Nassau County homeowners can start saving from month one with no upfront cost.
How much can a Long Island homeowner realistically save with solar?
It depends on your energy use, roof size, and current PSEG LI rate plan. Most GreenLogic residential solar customers see their monthly electric bill drop significantly from day one. Over the life of a system, 25 to 40 years, the cumulative savings routinely exceed the cost of installation by a wide margin. We model your specific numbers during the free consultation, so you're working with real projections, not industry averages.
How does PSEG LI net metering work for residential solar customers?
Net metering credits your PSEG LI account for excess electricity your residential solar panels generate and send back to the grid. Those credits roll over month to month and offset your bill during periods when your usage exceeds your production, like winter evenings or overcast stretches. GreenLogic designs every Long Island home solar system to maximize net metering value based on your specific location, roof orientation, and usage profile.
How long does a residential solar installation take on Long Island?
The physical installation typically takes one to two days. The full process from signed contract to Permission to Operate from PSEG LI runs 8 to 12 weeks on average, with most of that time driven by municipal permitting across Suffolk and Nassau counties. GreenLogic manages every step, including permit filing, utility interconnection paperwork, and inspection scheduling, so you don't have to track any of it yourself.
Will solar panels hold up through Long Island's storms and coastal weather?
Yes. Every GreenLogic residential solar system uses hurricane-rated racking and anchors engineered for Long Island's coastal conditions, whether you're in Southampton, Huntington, or anywhere in between. Roof penetrations are flashed, waterproofed, and covered under our warranty. In over two decades installing residential solar panels across Suffolk and Nassau counties, our systems have held up through every storm season the Island has thrown at them.
