Do solar panels work with snow on them

As solar energy becomes a staple of the American residential landscape, adoption is spreading rapidly from the sun‑drenched Southwest to the snowy expanses of the Northeast, Midwest, and Rocky Mountains. For a homeowner in Boston, Chicago, or Denver, the prospect of installing solar panels often brings a chilling question to mind: “What happens when it snows?” This comprehensive report serves as a definitive guide for US homeowners, dismantling the myths surrounding winter solar performance and providing actionable, science‑backed strategies for managing solar assets in cold climates.
Drawing on extensive data from the National Renewable Energy Laboratory (NREL), Sandia National Laboratories, and industry experts, this report establishes a counter‑intuitive truth: winter can be a highly productive season for solar energy. While snow accumulation poses a temporary physical barrier to sunlight, the physics of photovoltaic (PV) cells actually favor colder temperatures, allowing for peak efficiency during clear winter days. 1 Furthermore, the reflective properties of snow—known as the albedo effect—can significantly boost energy capture, particularly for modern systems designed to harvest reflected light. 3
This document navigates the technical realities of snow loss, which typically accounts for only 1% to 12% of annual production even in snowy regions. 5 It details the financial safety net provided by Net Energy Metering (NEM), which allows homeowners to “bank” summer sunshine to pay winter bills. 7 Crucially, it analyzes the economics and safety of snow removal, largely advising against manual intervention due to warranty risks and negligible financial returns, while providing safe protocols for those who choose to clear their arrays. 9 By understanding the interplay of thermodynamics, weather patterns, and system design, homeowners can confidently embrace solar power as a year‑round energy solution.

Section 1: The Science of Solar in the Cold

To understand how solar panels perform in winter, we must first look under the hood at the physics of how they generate electricity. There is a persistent myth that solar panels need heat to work, likely because we associate the sun with warmth. In reality, solar panels are electronic devices, and like your computer or smartphone, they function more efficiently in cool environments than in hot ones.

1.1 The Cold Weather Efficiency Boost

Solar photovoltaic (PV) panels work by converting photons (light particles) into electrons (electricity). This process occurs within semiconductor materials, typically silicon. Thermodynamics tells us that as temperatures rise, the efficiency of this conversion drops. Heat causes the atoms in the silicon to vibrate more rapidly, which creates resistance (impedance) to the flow of electrons. Conversely, when the temperature drops, this atomic vibration slows down, allowing electrons to move more freely. 1
This phenomenon creates a “cold weather voltage boost.” For every degree Celsius that the temperature drops below the standard test condition of 25°C (77°F), a solar panel’s voltage output typically increases by approximately 0.25% to 0.5%. 11
This creates a “cold weather voltage boost.” For every degree Celsius that the temperature drops below the standard test condition of 25°C (77°F), a solar panel’s voltage output typically increases by approximately 0.25% to 0.5%. 11
Consequently, a sunny day in January can actually produce a higher instantaneous power output (in watts) than a sunny day in July, simply because the electronics are running cooler and more efficiently. 2
This efficiency gain helps to counterbalance the fact that winter days are shorter and the sun is lower in the sky. While the duration of sunlight is less, the quality of the conversion process is higher.

1.2 The Myth of Solar Freezing

Homeowners often ask if solar panels can “freeze” or stop working in extreme cold. The answer is a definitive no. Solar cells are solid‑state devices with no moving parts or liquid components that could freeze. 13
In fact, most residential solar panels are rated to perform reliably in temperatures as low as –40°F (–40°C). 14
The materials used in panel construction—tempered glass, aluminum frames, and polymer backsheets—are subjected to rigorous “freeze‑thaw” cycle testing during manufacturing to ensure they can withstand the rapid expansion and contraction caused by fluctuating winter temperatures. While extreme cold is tough on batteries (which can lose capacity), the solar panels themselves thrive in the chill. 2

1.3 Light vs. Heat: Clarifying the Energy Source

It is vital to distinguish between irradiance (light energy) and temperature (heat energy). Solar panels run on irradiance.

Summer: High irradiance, high temperature. (High input, but lower conversion efficiency).
Winter: Lower irradiance (due to sun angle), low temperature. (Lower input, but higher conversion efficiency).

Even on cloudy winter days, UV rays penetrate the cloud cover. While production will be lower than on a clear day—typically 10% to 25% of rated capacity—the panels are still harvesting energy. 12 The system does not “shut off” unless the panels are completely buried under a thick, opaque blanket of snow.

Table 1.1: Solar Performance Factors by Season

Factor	Summer Impact	Winter Impact	Net Result
Daylight Hours	Long (14+ hours)	Short (9‑10 hours)	Summer has generation time advantage.
Sun Angle	Direct/Overhead	Low/Oblique	Summer has intensity advantage.
Panel Temperature	High (>140°F)	Low (<40°F)	Winter has efficiency advantage.
Snow Reflection	Low (Grass/Asphalt)	High (Albedo)	Winter has reflection advantage.
Obstruction	Leaves/Dust	Snow/Ice	Summer generally cleaner, though winter snow cleans panels.

Section 2: Snow Accumulation and Natural Shedding

When winter storms roll in, snow accumulation on solar panels is inevitable. However, the interaction between snow and solar panels is dynamic. Panels are not passive surfaces like a roof shingle; they are active, heat‑generating, glass‑faced devices that facilitate their own cleaning.

2.1 The “Greenhouse” Warming Effect

Even when covered by a layer of snow, solar panels are often still working to clear themselves. Light can penetrate through a thin layer of snow (forward scattering). Dark silicon cells absorb this filtered light and generate small amounts of heat. Because the panel is covered by a layer of snow, this heat is trapped, creating a localized “greenhouse effect” on the surface of the glass. 1
This warming effect creates a thin film of water between the glass and the snowpack. Water is a lubricant. Since most solar panels are installed at a tilt (typically between 30° and 45°), gravity takes over. The entire sheet of snow, lubricated by the meltwater underneath, will often slide off in one large mass. This is why homeowners often report seeing their solar panels clear days before the snow melts off the rest of their asphalt roof. 15

2.2 Variations in Snow Types

The impact of snow on solar production depends heavily on the type of snow:

Dry, Powdery Snow: This snow has low density and does not stick easily to the smooth glass surface. Wind can often scour a solar array clear of dry powder within hours of a storm, restoring full production. 15
Wet, Heavy Snow: Snow with high moisture content is denser and “stickier.” It is more likely to adhere to the panel and frame. However, its weight also helps it slide off once melting begins.
Ice and Crusting: The most difficult scenario is when wet snow falls, partially melts, and then temperatures plummet, freezing the snow into a crust. This can “cement” the snow to the panel frame, preventing the sliding mechanism. In these cases, the snow may remain until temperatures rise again. 13

2.3 Partial Shading and System Architecture

What happens if only the bottom half of the panels are covered in snow? In older solar systems (string inverters), this could knock out the production of the entire array, much like a single burnt‑out bulb on a string of Christmas lights.
However, modern residential systems typically use Microinverters or Power Optimizers.

Microinverters: These sit behind each individual panel. If the top row of panels clears of snow while the bottom row remains covered, the top row will immediately begin producing full power. The shaded panels do not drag down the clear ones. 18
Bypass Diodes: Most solar panels have internal bypass diodes that allow electricity to flow around shaded cells. If snow covers only the bottom third of a panel, the diodes can bypass that section, allowing the top two‑thirds to continue generating power. 19

This technology means that you don’t need a perfectly clear roof to generate electricity. As the snow slides and reveals the glass, energy production ramps up incrementally. 17

2.4 Structural Load: Can Panels Handle the Weight?

A common fear is that the weight of accumulated snow will crush the panels or the roof. This is extremely unlikely for code‑compliant installations.

Pressure Ratings: Standard residential solar panels are rated to withstand static snow loads of at least 5,400 Pascals (Pa). This translates to roughly 112 pounds per square foot (psf). 10
Real‑World Context:
- Light, fluffy snow weighs about 3‑5 lbs per cubic foot. You would need over 20 feet of snow on your panels to exceed the weight limit.
- Heavy, wet snow weighs about 20 lbs per cubic foot. You would still need over 5 feet of heavy snow standing directly on the panel to risk damage. 10
Mounting Strength: Solar racking systems are bolted into the roof’s rafters. Structural engineers calculate these loads based on local building codes, which account for historical maximum snowfalls. In heavy snow areas, installers may use more frequent attachment points or reinforced rails to ensure safety. 2

Section 3: Quantifying the Impact: How Much Energy is Really Lost?

Homeowners often overestimate the annual impact of snow. While it is true that a snow‑covered panel produces zero energy, the timing of these outages matters. Snow days typically coincide with the shortest days of the year when potential production is already at its lowest. Losing three days of production in December is much less impactful than losing three days in June.

3.1 NREL and Sandia Research Findings

Major studies by the National Renewable Energy Laboratory (NREL) and Sandia National Laboratories have quantified snow losses across the United States. The data is reassuring.

Annual Losses: For the vast majority of households in snowy climates, annual energy losses due to snow range from 1% to 12%. For most locations, the loss is in the single digits. 5
Monthly Spikes: While the annual loss is low, monthly statistics can look scary. In a particularly snowy January, a system might produce 50% to 100% less energy than predicted for that specific month. However, because January represents a small slice of the annual solar pie, this deficit is minor in the grand scheme of the year. 5

3.2 Regional Loss Profiles

Geography plays a huge role in snow loss. We can look at three distinct “snow archetypes” in the US to understand the variability.

Case Study 1: The Windy Plains (Denver, CO)

Snow Type: Often dry and powdery.
Weather Pattern: Denver experiences heavy snowfalls followed by brilliant, high‑intensity sunshine.
Solar Outcome: The high altitude (stronger UV radiation) and frequent sunny days mean snow melts or sublimates (turns directly to vapor) very quickly. Even after a foot of snow, panels are often clear within a day.
Typical Loss: Very low, often 1% to 5% annually. 22

Case Study 2: The Deep Freeze (Minneapolis, MN / Chicago, IL)

Snow Type: Variable, often wet and freezing hard.
Weather Pattern: Long stretches of sub‑freezing temperatures can prevent the “melt and slide” mechanism. Snow may sit on panels for weeks if temperatures stay near 0°F.
Solar Outcome: Losses here are higher because the snow sticks around. However, the extremely cold temperatures mean that when the panels do clear, they operate at peak efficiency.
Typical Loss: Moderate, ranging from 5% to 12% annually. 13

Case Study 3: The Wet Winter (Boston, MA / Northeast)

Snow Type: Heavy, wet snow and ice storms.
Weather Pattern: Frequent “Nor’easters” bring snow, but temperatures often fluctuate around freezing, aiding melting.
Solar Outcome: The main challenge is the lower tilt of many older roofs and the presence of trees. However, rain often follows snow, washing the panels clean.
Typical Loss: Moderate, typically 4% to 10% annually. 25

3.3 The “Cleaning” Benefit of Snow

There is a silver lining to snow accumulation: it cleans the panels. During dry months (summer and fall), dust, pollen, bird droppings, and soot can build up on panel surfaces, gradually reducing output by 1‑5% (soiling loss).
When a heavy snowpack slides off a panel, it acts like a squeegee. The snow bonds to the dirt particles and drags them off the glass. Homeowners often find that their panels are cleaner and more efficient in the spring than they were in the fall, thanks to this natural cleaning cycle. 15

---

Section 4: The Albedo Effect: How Snow Boosts Solar Power

One of the most fascinating aspects of winter solar production is the Albedo Effect. In simple terms, albedo is a measure of how reflective a surface is.

Low Albedo: Asphalt, grass, and soil absorb most sunlight. They have low reflectivity (0.1 – 0.25).
High Albedo: Fresh snow is one of the most reflective surfaces on Earth, reflecting 80% to 90% of the sunlight that hits it. 19

4.1 The “Light Bath”

When your yard and roof are covered in white snow, your solar panels are essentially sitting in a room full of mirrors. Sunlight doesn’t just hit them from above; it bounces off the snow on the ground, the neighbor’s roof, and the trees, hitting your panels from all angles.
This diffuse and reflected light can significantly boost production on clear winter days. It helps to compensate for the lower sun angle. A panel that might be struggling to find direct sun can still generate power from the immense amount of ambient light reflected by the snowpack. 1

4.2 Bifacial Panels: The Game Changer

Standard solar panels are “monofacial”—they have an opaque backsheet and only catch light from the front. A newer technology, known as bifacial solar panels, is becoming increasingly common in residential ground mounts and pergolas.

Double‑Sided Generation: Bifacial panels have glass on both sides. They catch direct sun on the front and reflected light on the back.
Winter Supercharge: In snowy conditions, bifacial panels are incredibly effective. The snow on the ground reflects light upward, hitting the back of the panel. Studies show that bifacial panels over snow can produce 15% to 30% more energy than standard panels. 14

For homeowners considering a ground‑mounted system in a snowy region, choosing bifacial panels is a smart move to maximize this winter advantage. Even vertical fences made of bifacial solar panels are being tested in snowy climates with excellent results, as they never get covered by snow and harvest the reflection perfectly. 3

Section 5: The Economics of Winter Solar: Why Zero Production Days Don’t Matter

If you are a homeowner looking at your monitoring app and seeing “0 kWh” production on a snowy Tuesday, it’s easy to panic. Is my investment failing? Am I losing money?
The financial model of residential solar is not built on daily production; it is built on annual averages. The key mechanism that makes this work is Net Energy Metering (NEM).

5.1 Net Metering Explained: The Grid as a Battery

For most grid‑tied solar homes, the electric grid acts like a giant, free battery.

Summer (The “Earning” Season): During long summer days, your system produces far more electricity than your home consumes. You don’t lose this extra power; it flows out to the grid, and your utility company credits your account. You are “banking” kilowatt‑hours. 7
Winter (The “Spending” Season): In December and January, when days are short and snow covers your panels, your production drops. You will likely consume more energy than you produce. However, instead of buying electricity from the utility, you “withdraw” the credits you banked in July. 32

This seasonal shifting means that a snow day doesn’t actually cost you money out of pocket today; it just uses up a small fraction of the surplus you generated months ago. As long as your solar installer sized your system correctly—factoring in that 5‑10% annual snow loss—your annual bill should still balance out to near zero. 7

5.2 The “True‑Up” Bill

Utility companies typically reconcile these credits once a year in a “True‑Up” bill.

If you produced more than you used over the entire year, you owe nothing (and might even get a small check for the surplus).
If you used more than you produced, you pay the difference.
Because the system is reconciled annually, the day‑to‑day volatility of winter weather is smoothed out. The snow on your panels today was essentially “paid for” by the sunshine in August. 34

5.3 Off‑Grid Considerations

For off‑grid homeowners (who are not connected to the utility grid), the story is different. They rely on batteries and cannot “bank” power with the utility. For these users, snow is a critical issue.

Action Required: Off‑grid users must often oversize their solar arrays significantly to account for winter losses or rely on backup generators.
Maintenance: Off‑grid owners are the one group for whom manual snow removal is economically essential, as a snow‑covered array means the lights go out once the batteries drain. 10

Table 5.1: Economics of Snow Removal for Grid‑Tied Homes

Scenario	Energy Saved (kWh)	Monetary Value (@ $0.15/kWh)	Cost of Professional Removal	Verdict
Light Dusting (1 Day)	10 kWh	$1.50	$150+	Don’t Do It
Heavy Storm (1 Week)	70 kWh	$10.50	$150+	Don’t Do It
Severe Month (4 Weeks)	300 kWh	$45.00	$300+ (Multiple visits)	Don’t Do It

As the table shows, paying for snow removal almost never makes financial sense for a grid‑tied home. You are spending hundreds of dollars to save forty dollars worth of electricity. 36

Section 6: To Clear or Not to Clear? The Great Debate

The most common question solar owners ask in winter is: “Should I rake the snow off my panels?”
The industry consensus is a resounding NO for most situations.

6.1 The Risks of Manual Removal

While it is tempting to clear your panels to squeeze out a few extra kilowatt‑hours, the risks generally outweigh the rewards.

Warranty Voiding: Solar panels are durable, but their anti‑reflective glass coatings are sensitive to scratching. Using a standard roof rake, a shovel, or even a broom with stiff bristles can scratch the glass. Many manufacturers explicitly state that damage caused by improper maintenance or manual snow removal voids the warranty. 9
Roof Damage: Scrabbling around on a roof with tools can damage shingles, dislodge wiring clips, or harm the racking system.
Personal Safety: Climbing a ladder to access a snowy, icy roof is incredibly dangerous. Falls from roofs are a leading cause of home injury. Even working from the ground with a long pole carries risks of slipping or dropping heavy snow onto yourself. 9

6.2 The “Do Nothing” Approach

The most effective strategy for 99% of homeowners is patience.

Trust the Design: Your system was likely designed with snow loss modeled in. It is performing as expected even when covered.
Let the Sun Work: As soon as the sun comes out, the panels will start to warm up. The snow will slide off on its own, usually within a few days.
Accept the Dip: Accept that January production will be low. It is a known feature of the system, not a bug. 17

6.3 When Removal MIGHT Be Necessary

There are rare exceptions where intervention might be warranted:

Low Pitch Roofs: If your roof is very flat (0‑10° tilt), snow may not slide off naturally and could accumulate for weeks.
Ice Dams: If snow accumulation on the panels is causing ice dams that threaten to cause leaks in your roof, removal is necessary for the sake of the home’s integrity, not just power production.
Off‑Grid Systems: As mentioned, if your battery is dying and you have no backup generator, you need those panels clear. 38

---

Section 7: Safe Snow Removal Protocols

If you fall into one of the exceptions above and must clear your panels, you must do so safely and correctly to preserve your warranty and your health.

7.1 The Golden Rules of Snow Removal

Stay on the Ground: Use a telescoping extension pole. Never get on the roof.
Use the Right Tool: NEVER use a metal shovel, a plastic snow shovel, or a standard garden rake. You must use a specialized snow rake with a soft foam head. These are often sold for clearing snow off luxury cars or specifically for solar panels (e.g., “Snow Brum”). 37
Don’t Clean Perfectly: Do not try to scrape the glass down to the bare surface. Your goal is to remove the bulk of the snow weight (the top 80%). Leave a thin layer of snow (an inch or so) on the panel. This ensures your tool never actually touches the glass. The sun will easily melt the remaining thin layer. 18
No Hot Water: Never spray hot water on cold solar panels. The thermal shock can shatter the tempered glass instantly. 9
No Rock Salt: Never use rock salt or calcium chloride de‑icers. They will corrode the aluminum frames and damage the roof mounting hardware. 9

7.2 Automated Solutions?

Some homeowners ask about heated panels. While technology exists (heating elements built into the panel), it is currently not standard for residential markets due to high cost and energy consumption. The energy required to melt the snow often exceeds the energy gained by clearing it. However, applying hydrophobic coatings (like a specialized wax for solar panels) can help snow slide off more easily, though these coatings need re‑application and have mixed results. 5

---

Section 8: Designing for the Cold: Optimizing Your System

If you haven’t installed solar yet, you can make design choices that minimize snow impact from day one.

8.1 Tilt Angle Optimization

The angle of your panels is the single biggest factor in how well they shed snow.

Steeper is Better: A panel tilted at 45° sheds snow much faster than one at 20°. In very snowy climates, installers often recommend a tilt angle equal to the latitude + 15 degrees. For example, in Minneapolis (Latitude 45°), a 60° tilt would be ideal for winter shedding and catching the low winter sun. 20
The Compromise: However, a steep 60° tilt might hurt your summer production when the sun is high overhead. Installers use sophisticated software to find the “sweet spot” angle that maximizes annual dollar value, balancing heavy summer production against winter snow shedding. 41

8.2 Placement and Orientation

Avoid Valley Shade: In winter, shadows from trees and neighbor’s houses get much longer because the sun is low. A tree that doesn’t shade your roof in June might block it completely in December. Advanced shading analysis is crucial.
Panel Layout: Placing panels in “landscape” orientation (long side horizontal) rather than “portrait” can sometimes help with shedding, as the snow has a shorter distance to slide to clear the panel (depending on the rail configuration). 20

8.3 Managing the Avalanche: Snow Guards

While we want snow to slide off panels, we don’t want 500 pounds of wet snow crashing down onto your front porch, your car, or your head. The glass surface of a solar panel is like a bobsled track; snow slides off it fast and hard.

The Solution: Solar Snow Guards. These are clamps or rails attached to the panel frame (like those from Alpine SnowGuards).
Function: They act like a friction strip, holding the snow on the panel so it melts slowly and drips off as water, or falls in small chunks, rather than avalanching all at once.
Trade‑off: Snow guards act against production. By holding snow on the panel, they keep the system covered longer. However, in areas with foot traffic below the roof, they are a necessary safety feature. 42

---

Section 9: Future Trends and Climate Outlook

As climate change alters weather patterns, the relationship between solar and snow is evolving.

More Extreme Precipitation: Climate models predict that while some areas will warm, others may experience more intense “dump” snow events due to increased moisture in the atmosphere. 44
Technological Advances: Researchers are developing clear, passive “snow‑phobic” coatings that can be applied to glass to make it slippery at a molecular level, preventing snow adhesion without requiring energy. 5
Bifacial Dominance: As bifacial panels become cheaper, they are likely to become standard for ground mounts and flat commercial roofs, turning the snowy landscape into a production asset rather than a liability. 19

Conclusion

For the US homeowner, the verdict is clear: Solar panels and winter weather can coexist beautifully.
While snow is a visual barrier, it is a temporary one. The combination of cold‑weather efficiency boosts, the albedo effect, and the financial banking of Net Metering ensures that solar remains a smart economic investment even in the snowiest corners of the country.
By resisting the urge to intervene, trusting the passive shedding mechanics of the panels, and prioritizing safety over a few kilowatt‑hours, homeowners can enjoy the benefits of clean energy year‑round. So, when the next blizzard buries your array, pour a hot cocoa, sit back, and know that your system is just taking a brief winter nap before waking up to harvest the brilliant winter sun.
