Can Snow Destroy Solar Panels?

The world has seen a sharp rise in the adoption of solar energy as an alternative, renewable source of energy. A key component of any solar system, is the solar panel. These are almost ubiquitous in solar energy set-ups, but with the onset of winter, many questions arise about how the inclement weather – snow, in particular – affects solar panels. This article takes a look at how snow affects solar panels, if snow is dangerous for them, and if it can destroy them.

What is snow and what are solar panels?

Snow is precipitation in the form of ice crystals. It forms when temperatures reach below freezing. Solar panels, on the other hand, are devices composed of photovoltaic cells that are used to convert sunlight into electricity. They are used in solar energy system because they capture sun’s energy and convert it into usable sources of energy that are then stored in batteries or other storage systems.

How does snow affect solar panels?

Snow can have a significant impact on solar panels. Firstly, snow can cover the panels and block the sun’s light from reaching them. This reduces the amount of solar energy that the panel is able to capture and in turn, reduces the amount of energy that is produced.

In addition to this, the weight of the snow can also damage the panel due to its heavy weight. If a panel becomes totally covered in snow, it may not be able to generate any energy at all. It is important to note that the snow has to be thick and/or heavy enough to physically press down on the panel in order for this to happen.

Is snow dangerous for solar panels?

When considering how dangerous snow is for solar panels, it largely depends on the type of panel being used. For example, if conventional solar panels are used that are exposed to direct sunlight, snow accumulation can increase the risk of damage or decreased performance. This is due to the amount of snow that accumulates on the panel, blocking direct sunlight from reaching it or meeting a certain weight capacity, both of which reduce the efficiency of the panel.

However, for panels that are used with anti-snow components or in rooftop solar installations, the effects can be far less significant. These anti-snow components include prismatic lenses, which cause snow to slide off the array naturally, as well as other mechanisms such as heated surfaces or even wind-powered mechanisms. Additionally, solar Energy system in rooftop installations has the added bonus of being protected from snow accumulation due to the roof.

Can snow destroy solar panels?

In short, it depends. While it is possible that snow could eventually destroy a solar panel, it is highly unlikely. Snow accumulation over time can cause a decrease in efficiency and even a decrease in the production of photovoltaic cells.

In addition, a thick layer of snow accumulation on a photovoltaic panel can put a heavy strain on the overall system and the supporting hardware, leading to cracks in the panel or its installation frame, resulting in damage or malfunctioning of the panel.

Even so, with proper maintenance and good installation, solar panels are designed to be resilient to weather forces such as snow and rain and to handle greater amounts of weight than what accumulated snow can place, making it highly unlikely for a solar panel to be destroyed by snow.


Overall, snow can have an effect on solar panels and can interfere with their production. Generally, this effect will be a decrease in production efficiency, but it is not something that will shut down the entire solar energy system. In the worst cases, snow accumulation might cause damage to the panels or their supporting structures, but ultimately, snow is unlikely to destroy solar panels. In order to maintain optimal production and a safe system, proper maintenance and regular clearing of snow is still advised, especially in cases where conventional solar panels are used.
