Most GreenLeaf customers go solar for $0 down using financing or a solar lease. Between federal incentives that can cover anywhere from 25% to 35% of a system's cost and New York State's solar tax credit of up to $5,000 plus NYSERDA rebates, going solar has never been more affordable. Every system we design is guaranteed to cost less than what you currently pay PSEG for electricity, and your exact price depends on your usage, which is why we start with a free custom quote.

With our solar program, there's no upfront cost and no waiting years to break even. You simply pay a low, predictable monthly rate for the power your panels produce, guaranteed to be less than what PSEG charges you today, and savings start with your very first bill. Monitoring and maintenance are included, so there's nothing to manage. Prefer to own your system outright? We offer that too, and we'll walk you through both options with real numbers from your actual electric bill.

Solar dramatically reduces it, and for many homes effectively replaces it. You'll still receive a small monthly service charge from PSEG to stay connected to the grid, but the electricity itself comes from your roof. With net metering, extra power your panels produce on sunny days earns credits that offset what you draw at night and in winter.

Yes. Studies consistently show homes with owned solar sell for more, and on Long Island, where electric rates are among the highest in the country, buyers understand exactly what a low electric bill is worth. Solar also tends to help homes sell faster.

If you own your system, it transfers with the home like any other upgrade and typically adds value. If you're on our solar program, the agreement transfers to the new homeowner, and buyers rarely object to inheriting a lower electric bill. Either way, we handle the paperwork with you.

Most residential installations take just 1 to 2 days on your roof. The full process from signed agreement to powering on, including engineering, permitting, and PSEG Long Island approval, typically runs 4 to 6 weeks. GreenLeaf handles every step of the paperwork for you.

No, never. Design, permitting, and installation are all handled by GreenLeaf employees working out of our East Setauket headquarters. The crew on your roof works for us, and the people who quote your system are the same people who stand behind it.

No, when installed correctly, solar actually protects the roof beneath it. Our crews use engineered mounting systems with sealed penetrations, and our 30-year warranty covers the roof work, not just the panels. If your roof needs repair or replacement first, we handle roofing too, so one company is accountable for all of it.

We offer panel removal and reinstallation as a service. Our own crews take the panels down, your roof gets done, and we put everything back and recommission the system. Because we installed it, there's no finger-pointing between contractors.

Only briefly. Most of the work happens on your roof and at your electrical panel. We'll need access to your electrical panel at the start and your OK at the end, but you don't need to take days off work.

Every GreenLeaf installation includes a 30-year warranty covering your panels, workmanship, and roof penetrations. And because we've been installing on Long Island since 2012, it's a warranty backed by a local company you can actually call, not a national installer that may not be around in year ten.

We install nationally trusted, industry-leading brands, including REC, Q CELLS, Silfab, and SEG Solar panels, Enphase microinverters, Tesla Powerwall batteries, and SnapNrack mounting. In fact, we're certified to install virtually every major brand on the market, so we're never locked into pushing one manufacturer. We recommend the equipment that fits your roof, your budget, and your goals, and we'll tell you honestly why.

Yes. Panels run on light, not heat, and actually operate more efficiently in cold weather. Production is lower on cloudy days and shorter winter days, which is why we design your system around your full year of usage. Net metering credits from sunny months carry you through gray ones. Snow typically slides off the panels within a day or two.

No, solar works without one, but a battery like the Tesla Powerwall keeps your essentials running during outages and stores your excess power. With Long Island's storm seasons, batteries have become our most requested add-on. We'll show you the numbers both ways.

Almost none. Panels have no moving parts, and Long Island rain does most of the cleaning. Your system includes monitoring, so both you and our team can see production in real time, and if anything ever underperforms, we know before you do.
