If you live in a region that experiences snow during the winter months, you’ve probably wondered how to keep your solar panels clear and functioning at full capacity. Snow buildup on solar panels can block sunlight and drastically reduce their efficiency. While it’s tempting to clear the snow as quickly as possible, doing so incorrectly could damage the panels or your roof.

In this guide, we’ll show you how to remove snow from solar panels safely, ensuring that your system continues to work efficiently while avoiding costly damage. We’ll also cover why it’s important to clear your solar panels and when you should leave the snow alone.

Why Removing Snow from Solar Panels Matters


Before jumping into the methods, it’s worth understanding why snow removal is necessary in the first place. While snow accumulation on solar panels might not seem like a big deal, it can have a significant impact on your solar energy production.

1. Decreased Solar Efficiency


Solar panels rely on sunlight to generate electricity, and when snow covers the panels, it blocks sunlight from reaching them. Even a light layer of snow can reduce the energy production of your panels. If the snow stays on for too long, it could lead to a noticeable drop in your electricity generation.

2. Potential Long-Term Damage


If snow is left on your panels for extended periods, it could potentially cause damage. Ice buildup can lead to cracks in the panels, while the weight of accumulated snow might put stress on the panels and roof. In some cases, the panels could even be dislodged, causing a costly repair.

3. Preventing Ice Dams


Snow can melt and refreeze, creating ice dams on the edges of your panels. Ice dams can be difficult to remove and, if left unchecked, can lead to leaks and water damage to your roof. Removing snow regularly helps prevent this problem.



When Should You Remove Snow from Your Solar Panels?


Not all snow needs to be removed immediately. Here are some things to consider before you start scraping off the snow:

1. Temperature and Weather Conditions


If temperatures are too low, the snow may be frozen solid, making it more difficult to remove. Additionally, it’s best to clear the snow after a fresh snowfall rather than letting it sit for days, as older snow may have turned to ice, which is harder to remove.

2. When Panels Are Covered


If your solar panels are more than 80% covered by snow, it’s a good idea to clear them off. A small dusting or a thin layer usually doesn’t significantly affect the panel's performance. You can wait for the sun to do its job and melt the snow if the layer is light.

3. Don’t Overdo It


If your panels are clean or only partially covered, there’s no need to remove the snow. Sometimes the snow will slide off the panels naturally, especially on tilt-mounted systems where the angle helps snow slide off more easily.



How to Safely Remove Snow from Solar Panels


Now that you know why snow removal is important, let’s discuss the best and safest methods for removing snow from your solar panels. Improper techniques can lead to scratches, cracks, or other damage to the panels, so it’s essential to be cautious.

1. Let Nature Do the Work


The easiest and safest method to remove snow from your panels is simply waiting for it to melt off naturally. Snow and ice will usually melt away during the day when the sun comes out, especially if the panels are tilted at a good angle. If the panels are installed at an angle of 30 to 45 degrees, snow can slide off on its own, especially if the temperature rises a little above freezing.

2. Use a Soft Brush


If waiting for the snow to melt isn’t an option, using a soft brush is the safest method for removing snow from your panels. Here’s how to do it properly:

  • Choose the Right Brush: Use a long-handled, soft-bristled brush (think of the type used for car washing) to gently sweep away the snow. Avoid using metal tools or brushes, as they can scratch the surface of the panels and damage the protective coating.

  • Work from the Top Down: Start at the top of the panels and work your way down. This method helps you avoid pushing snow and ice into the panel frame or roof area.

  • Gentle Strokes: Apply light pressure to avoid damaging the solar panel. Heavy force can crack the glass or dislodge the panels.


3. Use a Roof Rake with a Soft Blade


If there’s a significant amount of snow, a roof rake with a soft plastic blade can be an effective way to remove snow from solar panels. This tool is typically used to clear snow from your roof, but it can be adapted for solar panels as well.

  • Set Up the Roof Rake Properly: Make sure the rake is equipped with a non-abrasive, soft blade to avoid scratching the panels.

  • Stand Safely: Use the rake from the ground, standing on a stable surface to ensure you don’t fall or cause damage to the roof.


4. Avoid Using Hot Water


While it might be tempting to pour hot water on the snow to melt it off, this is not a good idea. Pouring hot water directly onto your solar panels can cause thermal shock, which might crack the glass. Water can also refreeze quickly, causing ice buildup around the panels or on the roof, which could cause more damage.

5. Hire a Professional


If you’re unsure about safely removing snow from your solar panels, it’s always a good idea to call a professional. Solar panel cleaning and maintenance experts have the proper tools and experience to handle snow removal without causing damage.

Precautions to Take When Removing Snow from Solar Panels


While removing snow from your solar panels, there are a few precautions you should keep in mind to protect both your panels and yourself:

1. Stay Safe


Safety is your top priority when working on the roof. If your panels are on a high roof or in a location that’s difficult to access, consider using fall protection gear, like a harness, or hiring a professional to do the job. Slippery surfaces can make working on the roof dangerous.

2. Avoid Pressure on the Panels


It’s essential to avoid putting too much pressure on the solar panels while removing snow. Pressing too hard can damage the glass or mounting system. Always use gentle strokes, and never stand on the panels.

3. Check for Ice Dams


While you’re removing snow, check for ice dams around the edges of your solar panels. Ice dams can form when snow melts and refreezes, leading to water damage. If you notice any ice buildup, it may be worth hiring a professional to remove it safely.

4. Clean After Snow Removal


Once the snow is cleared, take the opportunity to clean your solar panels. Dirt and debris that have accumulated during the winter months can also reduce the efficiency of your panels. Use a gentle cleaning solution and soft cloth or sponge to wipe down the surface, avoiding harsh chemicals or abrasive scrubbers that could damage the glass.



When Should You Not Remove Snow from Solar Panels?


In some cases, removing snow from your solar panels may not be necessary or advisable:

1. Thin Layer of Snow


If the snow layer is thin and doesn’t significantly block sunlight, it’s probably best to leave it alone. Solar panels are designed to function even with some snow on them. The snow may naturally slide off as temperatures rise or when the sun melts it.

2. Risk of Damage


If your roof is particularly steep or the snow is frozen solid, attempting to remove it yourself could cause more harm than good. In these cases, it’s often best to leave the snow on the panels until conditions are more favorable or to call in professionals.



Conclusion


Snow buildup on solar panels is a natural occurrence during the winter months, but it’s essential to address it properly to ensure that your solar system continues to work efficiently. By using safe and gentle methods to remove the snow, you can protect your panels from damage while maintaining optimal energy production.

Remember to always prioritize safety when working on your roof. If you're unsure or uncomfortable handling the removal process yourself, don’t hesitate to reach out to professionals who can get the job done safely and effectively.
