Can Solar Panels Survive & Thrive in a Canadian Winter?

As winter blankets most of us in snow, many potential solar power users wonder: Can solar panels work in the winter? The short answer is yes, they can! In fact, solar energy systems are designed to harness the sun’s rays year-round, even in the coldest months. In this blog, we’ll explore how solar panels perform in winter conditions, the impact of snow, and the advantages of different mounting options.

Solar Power in the Winter

Canada’s winter sun may be less intense, but solar panels can still generate electricity. Snowy days aren’t necessarily a bad thing. The lower temperatures and the reflective properties of snow can actually increase solar panel efficiency. In fact, panels typically produce around 30% more energy at -40 Celsius. When the sun shines on the snow-covered ground, the light bounces back, allowing your panels to capture even more energy.

As long as sunlight reaches a solar panel, it generates electricity. Any reduced output in winter mostly results from substantial snowfall and shorter daylight hours.

 

Solar Panels and Snow

One of the biggest concerns with relying on solar in the winter is the accumulation of snow on rooftop solar panels. Solar panels are connected in long strings, if snow is covering just a portion of one panel, it renders the whole array useless. While the snow can temporarily obstruct sunlight, most solar panels are designed to shed light snow pretty easily. The heat generated from the panels during sunny spells can melt the snow quickly. However, heavy snow can pose challenges. Here are some key points to consider:

  • Solar Panel Weight: Solar panels are relatively heavy. It’s essential to ensure that your roof can support their weight, especially when combined with snow accumulation.
  • Fire Hazard: Improperly installed solar panels can become a fire hazard if not maintained correctly.
  • Snow Removal: Depending on your setup, sometimes removal of snow isn’t possible or can’t be done safely. You can also damage your panels in the process if you aren’t careful.

Another concern with the winter up north is shortened daylight hours. While solar panels do not generate electricity at night, you can still harness solar power effectively. By installing a solar battery storage system, you can store excess energy generated during the day for use after sunset. This way, you can become your own power provider, enjoying the benefits of renewable energy around the clock.

 

Pole-Mounted vs. Roof-Mounted Solar Panels

If you have the space for it, we always recommend a pole-mounted solution over a roof mount. Here are some of the advantages of both setups:

Pole-Mounted Solar Panels:

  • Flexibility: These systems can be adjusted to optimize sun exposure throughout the year.
  • Easier Snow Removal: Snow sliding off can be less of an issue with pole-mounted panels, as they are often installed at an angle or completely vertical.

Roof-Mounted Solar Panels:

  • Space-Saving: Ideal for homes with limited yard space.
  • Aesthetics: They often blend more seamlessly with your home’s design.

 

Ultimately, selecting the right mounting option will ensure that you maximize the benefits of your solar energy system. While roof-mounted panels can be a good fit for homes with limited space, pole mounts offer enhanced performance and easier maintenance in winter conditions.

Embracing Solar Energy Year-Round in Canada

Solar energy is a viable option in Canada, even during the winter months. By understanding how solar panels work in winter and the best practices for snow management, you can confidently embrace solar power and live “off-the-grid”. With the right setup, including options like pole mounts and snow guards, you can ensure your solar system remains efficient year-round.
