Do Solar Panels Work in Winter?

As winter is in the distance, many businesses may wonder: do solar panels work in winter? It’s a common question, especially in colder climates where sunlight hours are shorter, and snowfall is a regular occurrence. As a leading commercial solar panel installation company, we’re here to shed light on this topic and provide insights into how solar panels perform during the winter months.

Understanding Solar Panel Efficiency

To answer the question of whether solar panels work in winter, it’s essential to understand how solar panels function. Solar panels generate electricity by converting sunlight into usable energy through photovoltaic cells. However, solar panel efficiency can be affected by various factors, including temperature, sunlight intensity, and shading.

Winter and Solar Panel Efficiency

While it’s true that solar panels rely on sunlight to generate electricity, they can still produce power even on cloudy or overcast days. However, colder temperatures can actually improve solar panel efficiency to some extent. Solar panels operate more efficiently in cooler temperatures, which can offset the reduced sunlight hours during winter months.

Snow and Solar Panels

One concern many people have about solar panels in winter is snow accumulation. While snow can temporarily block sunlight from reaching solar panels, it typically doesn’t pose a significant problem. Solar panels are designed to be durable and self-cleaning, meaning that snow will often slide off or melt away once sunlight returns. Additionally, solar panels are typically installed at an angle, allowing snow to slide off more easily.

Tips for Maximising Solar Panel Performance in Winter

To ensure optimal performance of your solar panels during the winter months, here are some tips from our experts:

  1. Keep Panels Clear of Snow: If snow does accumulate on your solar panels, gently brush it off with a soft broom or brush. Avoid using metal tools or abrasive materials that could damage the panels.
  2. Monitor System Performance: Keep an eye on your solar panel system’s performance throughout the winter. If you notice any issues or significant decreases in energy production, contact a professional for assistance.
  3. Consider Tilted Mounting: Tilted solar panel mounting systems can help shed snow more easily and maximise sunlight exposure, especially in areas with heavy snowfall.
  4. Invest in Energy Storage: Consider investing in energy storage solutions, such as batteries, to store excess energy generated during sunny days for use during cloudy or overcast periods.


In conclusion, solar panels can indeed work in winter, albeit with some considerations. While colder temperatures may affect sunlight hours, solar panels can still generate electricity, and in some cases, may even operate more efficiently. By following the tips outlined above and working with experienced professionals, you can ensure that your solar panel system performs optimally year-round, even during the winter months.
