How To Clear Snow Off Solar Panels

Solar panels have become increasingly common as more homeowners and businesses opt for sustainable energy sources. However, with the beauty and serenity of winter comes the challenge of snow-covered panels. Snow, while picturesque, can be a damper on the efficiency of these energy generators.

Snow not only obscures sunlight but its reflective nature can further reduce the amount of light reaching the panel's surface. A clear panel not only looks good but ensures optimum energy conversion and maximum returns on your solar investment.

Why It's Essential to Remove Snow from Solar Panels

Energy Efficiency and Snow Coverage

Solar panels work by converting sunlight into electricity. Snow-covered panels mean less sunlight and therefore, reduced energy output. According to several studies, even a light layer of snow can significantly reduce energy production. To put this into perspective, let's look at some data:

Snow Thickness Approximate Energy Reduction
1 inch 20%
2 inches 40%
3 inches 60%

The above table indicates how even a slight accumulation can lead to substantial energy losses.

Potential Hazards of Snow Accumulation

Apart from energy inefficiency, snow accumulation poses other risks:

  • Weight Stress: Solar panels are designed to bear a certain weight. Excessive snow can strain the panels, potentially damaging them.
  • Melting and Refreezing: As snow melts, water can seep into cracks or crevices and upon freezing, expand, causing structural damage.
  • Ice Dam Formation: Melting snow can lead to the formation of ice dams which not only hinder panel efficiency but also pose risks of falling ice.

Moreover, if panels are not cleared, the accumulated snow might pose a danger of falling snow sheets, especially in sloped installations.

As snow affects both the energy efficiency and the structural integrity of solar installations, knowing how to clean solar panels on the roof is of paramount importance.

Best Methods to Clear Snow Off Solar Panels

Safe Brushing Techniques

Brushing is one of the most straightforward ways to remove snow from your solar panels. However, choosing the right brush and employing the right technique are vital to ensure you don’t damage the panels.

  • Using Soft Bristle Brushes: Hard bristles can scratch the surface of solar panels. Soft bristle brushes, especially those designed for car washing or solar panel cleaning, are ideal. They are gentle on the panel surface yet effective in removing snow.
  • Proper Technique to Avoid Damaging Panels: Always brush in a downward motion, ensuring you move the snow off the panel rather than pushing it around. This minimizes the chances of scratching or damaging the panel surface. For a more in-depth cleaning guide, our post on how to clean solar panels on the roof provides extensive information.

Tilting the Panels

Some modern solar installations come with adjustable angles, allowing you to tilt the panels.

  • Benefits of Having Tiltable Solar Panel Setups: By tilting the panels, snow slides off due to gravity, minimizing accumulation. Additionally, tilting can optimize the angle for winter sun, improving energy efficiency. If you’re unsure about adjusting your panels, our guide on how to clean solar panels from the ground might offer some insights.

Using Specialized Snow Rakes for Solar Panels

If your panels are out of reach, a specialized snow rake might be your best tool.

  • Features to Look for in a Snow Rake: Ensure that the rake has an extendable handle and soft edges to avoid any damage. Plastic edges or rubberized coatings are recommended.

Automated Solutions

Innovation in the solar industry has led to the introduction of automated solutions that either prevent snow accumulation or assist in its melting.

  • Heated Panels: Some high-end panels come with a heating system that can melt away snow.
  • Automated Brushes: Just like automated car wash systems, there are brushes designed to clear off snow periodically.

Preventive Measures

Preventing snow from sticking in the first place is an ideal solution.

  • Surface Treatments or Coatings: Specialized treatments can make the surface of solar panels slippery, preventing snow adherence. For more on cleaning and treatments, dive into our guide on what is the best way to clean solar panels.

Safety Precautions When Clearing Snow

Clearing snow off solar panels isn’t just about the panels. Your safety is paramount.

Never Stand Directly Under Snow-Laden Panels

The weight of the snow can cause it to slide off suddenly, especially if the panels are angled. Always ensure you stand to the side when clearing snow.

Power Safety

Before attempting any cleaning, especially if it involves water or liquids, always consider the electrical safety aspects. This might make you wonder: do I need to turn off solar panels to clean?

Avoid Metal Tools or Hard Scrapers

While it might be tempting to use a metal scraper for that stubborn ice, it's a risk not worth taking. Metal can easily scratch or damage the surface of your panels.

Ensure Safety When Climbing Roofs

If you need to get on the roof to clear the snow, make sure you’re using proper safety gear. Slippery roofs can be treacherous, especially in winter. Ensure you’re tethered and are using non-slip boots. Before attempting, always ask: is it safe to clean solar panels?


In the world of renewable energy, solar panels stand out as one of the most sought-after choices, offering a sustainable and eco-friendly power alternative. As we navigate the seasons, winter emerges as a particular challenge for these sun-powered devices. Keeping solar panels free from snow is more than just about aesthetics; it's about safeguarding the efficiency and longevity of your investment.

Solar panels, much like any other equipment, require regular maintenance. Snow, as serene and beautiful as it might appear, can significantly reduce the panel's efficiency. By promptly clearing it off, you ensure that your panels are harnessing as much sunlight as possible, translating to more energy and savings for you.
