Winter’s beauty often comes with challenges, especially for solar panel owners. When snow blankets your solar panels, it can block sunlight, reduce energy production, and even risk long-term damage. That’s why understanding how to remove snow from solar panels is essential for maintaining their efficiency and protecting your investment. Knowing how to remove snow from solar panels safely not only ensures optimal energy output but also prevents costly repairs caused by improper handling. In this article, we’ll explore practical methods to clear snow, prevent damage, and keep your solar system running smoothly, no matter how harsh the winter gets.
Why is Snow on Solar Panels a Concern?
Snow on solar panels may seem like a minor inconvenience, but it can have a significant impact on the performance and longevity of your system. Here’s why snow on solar panels is a concern that every solar panel owner should take seriously.
1.) Reduced Energy Output
Solar panels rely on sunlight to generate electricity. When snow accumulates on the surface of the panels, it creates a barrier that blocks sunlight from reaching the photovoltaic cells. This can cause a substantial drop in energy production, as the panels will be unable to capture the light necessary for converting it into usable energy.
In some cases, snow can reduce solar panel output by up to 90%, depending on how thick the snow cover is. Even a thin layer of snow can cause a noticeable decrease in the system’s performance, especially during the colder months when solar energy production tends to be lower.
2.) Risk of Long-Term Damage
If snow is left on the panels for an extended period, it can lead to more serious issues beyond just reduced energy production. As the snow sits on the panels, it can trap moisture underneath the surface, which could eventually lead to frozen water. This frozen moisture can cause stress on the panels and even damage the internal components, such as the electrical connections and the solar cells themselves.
If ice forms and remains under the snow, it could cause structural damage, including cracks in the glass or damage to the wiring. Over time, this can lead to expensive repairs or the need for complete replacement of the solar panels.
3.) Increased Weight on the Racking System
The weight of accumulated snow on solar panels can also put extra strain on the racking system that holds the panels in place. Solar panel racking is designed to bear a certain load, but heavy snow can exceed the weight limits and cause damage to the frame or mounting structure. This could cause the panels to shift, which in turn may lead to misalignment or dislodging of the panels, affecting their overall functionality and lifespan.
4.) Frozen Moisture Trapping Under the Panels
As snow melts and refreezes, moisture can become trapped between the panels and the roof. This trapped moisture can cause problems, particularly if it freezes again, creating a layer of ice. Ice under the solar panels can restrict airflow and even cause damage to the roof if it leads to leaks or further freezing over time. If left unchecked, this trapped moisture could lead to structural damage to the panels and the roof itself, resulting in costly repairs.
5.) Increased Cleaning Efforts
If snow is left on solar panels for too long, it may become compacted and harder to remove. As it melts and refreezes, the snow could form a thicker layer of ice, which becomes much more difficult to clear. Manual removal of hardened snow and ice can lead to scratches or damage to the panels, especially if the wrong tools are used. Therefore, it’s essential to remove snow promptly to avoid complicated cleaning efforts and potential damage to the panels.
6.) Uneven Heating and Performance
Solar panels work most efficiently when they are evenly exposed to sunlight. When snow accumulates on one part of the panel and not another, it can cause uneven heating. The differing temperatures on the panel can create thermal stress, potentially leading to panel degradation over time. This uneven performance can also reduce the overall energy output and strain the system.
How to Remove Snow from Solar Panels
Now that we’ve established why snow removal is so important, let’s get into the best practices for clearing snow off your solar panels without causing damage.
1.) Use the Right Tools
To safely remove snow from your solar panels, you’ll need to use the right tools to avoid scratching or damaging the surface. Here are the tools you should use:
- Roof rake with a soft foam head: A roof rake is ideal for removing snow from solar panels. Make sure it has a foam head or a soft brush to avoid scratching the panels.
- Broom with soft bristles: A long-handled broom can also be used to gently sweep off light snow. Again, ensure the bristles are soft to prevent scratching the panels.
- Snow blower (only for ground-mounted panels): If your solar panels are mounted on the ground, a snow blower with a rubber or plastic attachment can be used to clear snow efficiently.
2.) Start from the Edge
When removing snow, always start from the edges of the solar panels and work your way towards the center. This allows you to clear away large chunks of snow without putting too much pressure on the panels themselves. Be careful not to push or pull too hard, as this can cause damage to the fragile surface of the panels.
3.) Avoid Metal Tools
While it may be tempting to use a metal shovel or a scraper to clear away snow, never use metal tools on solar panels. Metal can easily scratch the surface, which can damage the protective glass and reduce the panels’ effectiveness. Instead, always use tools designed specifically for snow removal from solar panels.
4.) Use Warm Water (But Not Hot Water)
If the snow is particularly stubborn or frozen, you can use warm water to help melt it. However, be careful not to use hot water, as the temperature shock can crack the glass or damage the panels. Warm water is gentle enough to melt the snow but won’t cause harm to the panels.
5.) Avoid Stepping on the Panels
It’s essential that you never step directly on your solar panels, even if there’s snow covering them. Walking on the panels can damage the surface, leading to costly repairs or even a complete replacement. Always use a roof rake or broom to clear the snow, and if you need to access the panels, use a safe ladder and ensure you’re properly secured.
6.) Be Cautious of Ice
If snow has turned to ice on your solar panels, be particularly careful. Ice is difficult to remove, and scraping it off could cause significant damage. In such cases, consider using a de-icing solution or gentle heat, such as a hairdryer or heat gun (on a low setting), to melt the ice before removing it with a soft broom or brush.
Effective Ways to Prevent Snow Damage to Solar Panels
Removing snow is only part of the equation. The best way to protect your solar panels is to take preventative measures that minimise snow buildup in the first place. Here are a few tips to help prevent damage:
1.) Install Panels at the Right Angle
2.) Use Solar Panel Covers
During particularly harsh winter conditions, consider using solar panel covers designed to protect the panels from snow and ice. These covers can keep your panels clean and prevent snow accumulation, ensuring that they perform optimally throughout the winter months.
3.) Schedule Regular Maintenance
Even though solar panels are generally low-maintenance, it’s important to inspect your panels regularly to ensure they’re in good condition. If you live in an area that experiences heavy snowfall, it’s advisable to schedule routine maintenance with a professional to ensure your solar system is working as efficiently as possible.
4.) Ensure Proper Drainage
If your panels are mounted on a flat roof, you’ll need to ensure there is proper drainage to allow melting snow to flow off the panels. Clogged gutters or poor drainage can lead to water pooling and freezing under the panels, which can cause significant damage over time.
5.) Install Heating Elements
Some solar panel systems come with heating elements installed beneath the panels to help melt snow and ice automatically. These systems can be quite expensive but are highly effective in preventing snow buildup and protecting your panels from damage.
