How to Remove Snow From Solar Panels

To remove snow from solar panels, stand on the ground and pull the snow down with a soft foam snow rake. Use light passes. Never use metal tools, hot water, or a ladder. If the snow is light and the sun is out, wait. Most panels shed snow on their own.

Snow does cost solar owners some power, but less than most people fear. The U.S. National Renewable Energy Laboratory (NREL) found that snow cuts yearly solar output by 0% to 16% across the lower 48 states. The worst spots were in Minnesota and Michigan. A 2023 review in Energy Advances reports that a southern Ontario study measured yearly snow losses of about 3% for low-tilt panels, and even less for well-tilted ones.

So a few snowy days will not ruin your year. A cracked panel will. That is why the way you clear snow matters more than how fast you clear it.

Should You Clear Snow Off Solar Panels at All?

Often, no. Solar panels have smooth glass and a slope. Dark glass soaks up even weak winter sun, so it warms up and the snow slides off. Many solar installers say panels shed snow faster than the roof around them.

Cold weather also helps your system. Panels make power more easily when it is cold. Short winter days cause most of the winter drop, not the cold.

When You Should Wait

Let the snow melt on its own when:

• The snow is light and fluffy
• The forecast shows sun in the next day or two
• Your panels sit on a steep roof
• You cannot reach the panels from the ground
• The wind is strong or the ground is icy

When You Should Clear the Snow

Clear the snow when:

• Heavy, wet snow covers most of the array and will not slide
• The weather stays below freezing for many days
• Your panels sit at a low angle
• Trees or a chimney shade the roof and slow the melt
• Your solar app shows near-zero power and no warm weather is coming

Do the work only if you can stay on the ground. If you need a ladder or a roof walk, skip it. The few extra kilowatt-hours are not worth a fall.

How to Remove Snow From Solar Panels Step by Step

Follow these steps in order. Each one keeps you safe and keeps your panels scratch-free.

Step 1: Check Your Warranty First

Some warranties limit how you can clean or touch the panels. Read yours, or call your installer. A short call can save you a costly claim later.

Step 2: Pick a Soft Tool

Use a snow rake made for solar panels. Look for a foam or rubber head and a long, light pole. Stay away from hard edges.

Pole length matters:

• One-story homes often need a pole of about 15 to 20 feet
• Two-story homes often need about 20 to 30 feet

If you have to lean or stretch to reach, stop. Your footing matters more than the snow.

Step 3: Stand to the Side

Snow can slide off in one big sheet. Never stand right below the array. Stand to the side, keep your feet wide, and wear boots with good grip. Keep kids and pets away.

Step 4: Pull the Snow Down in Light Passes

Hold the rake head flat. Pull the snow down in small strokes. Start at the bottom edge and work up. This keeps new snow from piling up at the lower edge as it slides.

You do not need bare glass. A thin layer is fine. Light still reaches the cells through a thin layer of snow, and the sun will melt the rest.

Step 5: Stop at the Ice

Ice often forms along the bottom edge of the panels after a thaw and a freeze. Do not chip it. Do not pry it. Do not pour hot water on it. Hot water on cold glass can cause thermal shock, and that can crack the panel. Wait for a warmer, sunny window instead.

Step 6: Check Your Panels

When you finish, look at the array from the ground. Check for cracks, loose wires, or panels that moved. Then check your solar app. Power should climb back up once the snow clears. If it stays low for days, call your solar installer.

Ground-Mounted Panels: A Quick Note

Ground-mounted panels are easier to reach, but the same rules apply. Use a soft broom or a foam head. Sweep with gentle strokes. Do not lean on the glass. Watch for wires and metal edges, and keep the ground in front of the panels clear so snow does not pile back up.

Tools and Tricks to Avoid

Some quick fixes cause real damage. Skip these:

• Metal shovels and scrapers: They scratch the glass and the coating
• Stiff brushes: Trapped grit can scratch the surface
• Hot water: It can crack cold glass
• Rock salt and de-icers: They can leave a residue and harm the roof and the system
• Pressure washers: The force can break seals and damage wires
• A standard roof rake: Hard edges and bolts can catch on the frame

A leaf blower can help with light, powdery snow. Keep the nozzle away from the glass and use a soft, plastic tip.

Safety Tips for Ottawa and Toronto Winters

Winters in Eastern Ontario and the Greater Toronto Area bring heavy snow, hard freezes, and sudden thaws. That mix creates ice and sliding snow.

In Ottawa, homes in Kanata, Barrhaven, Orleans, and Nepean often see deep snow that stays for weeks. From Parliament Hill to the Rideau Canal, the city can feel like one big snow globe by January. Cold stretches can last, so snow may stay on a low-angle array longer.

In Toronto, homes in Scarborough, Etobicoke, and North York often see snow followed by freezing rain. The CN Tower may stand tall above the city, but your panels face the same icy lip at the bottom edge. Quick thaws followed by hard freezes make that ice worse.

Keep these local habits:

• Check the forecast before you go outside
• Skip the job during freezing rain or high wind
• Keep a clear drop zone below the panels
• Wear traction boots and work in daylight
• Call a pro if the roof is steep or icy

How to Keep Snow From Piling Up Next Time

You cannot stop every storm, but you can cut your workload. Try these ideas:

• Tilt: Steeper panels shed snow faster. Ask your installer about the best angle
• Sun: Trim trees that shade the roof so the sun reaches the glass
• Airflow: Panels with space under them can shed snow sooner
• Snow guards: These break big slides into small ones. They protect people and gutters below, but they can hold some snow on the roof
• Clear ground: On ground mounts, keep the area in front of the panels free of snow so slides do not pile back up

Do Not Forget the Ground Below Your Panels

When snow slides off your array, it lands somewhere. That spot can become a heavy pile near your driveway, walkway, or front door. The pile can block your path and turn into ice.

Clear that landing zone before and after a storm. Move patio furniture and grills out of the way. Keep paths open so you can reach your panels from the ground when you need to.

If you live in the capital, a reliable snow removal service Ottawa homeowners can call can handle this for you. If you live in the GTA, a local snow removal service in Toronto for homes and driveways can keep the same areas clear all season.

Signs You Should Call a Professional

Some jobs are too risky for DIY. Call a pro when:

• You cannot reach the panels from the ground
• The roof is steep, icy, or high
• Snow slides off in large sheets over a walkway
• Ice builds up again and again at the bottom edge
• You see a cracked panel, loose wiring, or a sudden power drop that does not recover

For roof arrays, your solar installer is the first call. They know your system and your warranty. For the snow and ice around your home, a local snow crew can step in fast.

FAQ

Can I use a regular roof rake on solar panels? 

It is risky, because hard edges and bolts can scratch the glass, so use a soft foam rake made for panels.

Will snow damage my solar panels? 

Not usually, because most panels handle heavy snow, and damage mostly comes from scraping or hitting the glass.

How long does snow take to melt off solar panels? 

On a sunny day, snow often slides off in a day or two, even in cold weather.

Can I pour warm water on the panels to melt snow? 

No, because sudden heat on cold glass can crack it.

Who should I call if I cannot reach my panels safely? 

Call your solar installer for roof arrays, and call a local snow crew to clear the ground, driveway, and walkways below.
