Solar panels work all winter in New York, snow and all. Even so, we hear the same worries from homeowners every fall, and they are fair ones when parts of the state see more than 200 inches of snow a year and January days are so short.
Most of those worries trace back to five misconceptions, so let’s walk through what actually happens on your roof between November and March.
60-second summary
The short version, if you’re wondering how solar holds up in a New York winter.
- Cold weather
- Panels run on light, not heat. Cold actually helps them convert sunlight more efficiently, and it’s heat that wears panels out.
- Clearing snow
- You don’t need to. Panels are smooth glass, tilted and dark, so snow slides and melts off faster than it does from the rest of your roof.
- Snow cover
- A light dusting barely matters. A heavy storm pauses production for a short stretch, and it picks right back up once the glass is exposed.
- Winter bills
- Production runs 15% to 40% below summer, but your bill doesn’t have to follow, because summer credits cover the gap.
- System design
- Design decides winter performance more than weather does. A well-engineered system accounts for your roof, local snowfall and your region.
Net metering In spring and summer your system often makes more than you use, and the extra goes to the grid as credits. You draw those credits back down in winter, which is why shorter days and a few snowed-in days don’t have to raise your bill.
Misconception #1: Solar panels need warm weather to work
Panels run on light, not heat, which means that as long as sunlight reaches them on a 25°F morning, they are producing electricity. The temperature outside has very little to do with how much power your system makes, because what really counts is how much direct sunlight lands on the panels each day.
In fact, the cold works in their favor. Lower temperatures improve electrical conductivity, so a panel converts sunlight into power more efficiently on a crisp, clear day than on a sweltering one. If anything, heat is the real enemy, because in places that regularly top 110 degrees, panels live under constant stress and wear out sooner. New York’s moderate climate, by contrast, is easier on your system and helps it last, which is a long-term advantage that homeowners in hotter states don’t get.
Misconception #2: You have to clear the snow off your panels
You don’t, and honestly we would rather you didn’t, because your panels shed snow on their own and do it faster than the rest of your roof. That comes down to three things working in their favor:
- They are glass. The surface of a panel is smooth tempered glass, so snow has far less to grip than it does on rough shingles.
- They are tilted. Most systems sit at an angle, and once the bottom layer loosens, the whole sheet slides off.
- They are dark. Panels absorb heat, so even weak winter sun warms the glass and melts the layer touching it.
So you can leave the roof rake in the garage. Climbing an icy roof is dangerous, and besides, scraping can scratch the glass. The snow is on its way off anyway, and it even does you a small favor on the way down by taking the fall’s dust and debris with it.
Misconception #3: A snowy winter means months of lost production
Snow pauses production for a short while, but it does not end it for the season. A light dusting barely matters at all, since sunlight still passes through a thin layer. A heavy storm is different, because it can cover the panels completely and leave them producing very little for a stretch. As soon as the glass is exposed again, though, production picks right back up. None of this catches a good installer off guard, either, because local snowfall is part of the math when a system is designed for a New York roof.
On top of that, a few snowed-in days cost you less than you might think. With net metering, the credits your system banked over the summer cover the days your panels sit under snow, so your savings are measured over the year rather than over one storm.
Misconception #4: Less winter sun means higher winter bills
It is true that your panels produce less in winter, typically 15% to 40% below summer depending on where you live in New York. What most people don’t know is that your bill does not have to follow.
That’s because net metering closes the gap. In spring and summer your system often makes more than you use, and the extra goes to the grid as credits that you then draw back down in winter. To see how that plays out, take a 10 kW system in Buffalo that might generate around 1,000 kWh in April and 650 kWh in January. Because the summer surplus carries through the cold months, the homeowner is often left with little to no electric bill by year’s end.
A home battery takes this a step further, storing midday power for the evening and keeping the lights on when a storm or ice takes the grid down.
Misconception #5: The weather decides how well your system performs
It is easy to blame the weather, but design is what really decides it. Two neighbors on the same street, under the same sky, can get very different winters out of their panels. The difference is that a well-engineered system accounts for:
- Your roof’s tilt, shading and orientation
- Local sunlight hours and snowfall data
- Regional differences across New York
That last point matters the most, since what works for a home in Buffalo may not perform the same way in Westchester County or on Long Island. This is why, at Empire Solar, we design every system for the full year, so the savings stay steady through every season.
Final Thoughts
So winter changes how your panels perform, but it does not stop them: the cold helps, the snow slides off, and your summer credits cover the shorter days.

Frequently Asked Questions
Do solar panels work in the winter in New York?
Yes. Panels run on sunlight, not heat, so they keep producing on cold days as long as light reaches them. Cold temperatures even help them convert that light more efficiently.
Should I clear snow off my solar panels?
No. Panels are smooth, tilted and dark, so snow slides and melts off on its own. Climbing an icy roof is dangerous, and scraping can scratch the glass.
Do solar panels still produce power when they are covered in snow?
Under a light dusting, yes, because sunlight passes through a thin layer. A heavy storm can pause production for a short stretch, and it resumes as soon as the glass is exposed.
How much less do solar panels produce in winter?
In New York, winter production typically runs 15% to 40% below summer, depending on where you live. A well-designed system already accounts for that drop.
Will my electric bill go up in winter with solar?
With net metering, the extra power your system sends to the grid in spring and summer earns credits. You draw those credits down in winter, when production is lower.
Do I need a battery for winter?
No, your system works without one. A battery adds backup: it stores midday power for the evening and keeps the lights on when a storm takes the grid down.
How does Empire Solar design systems for New York winters?
We design every system for the full year. That means accounting for your roof’s tilt, shading and orientation, local sunlight hours and snowfall, and the differences between regions like Buffalo, Westchester County and the Hudson Valley.
