Do Solar Panels Work in the Wintertime?

Solar Panels in the Winter

Solar energy works by capturing the sun’s energy and turning it into electricity for your home or business. While the sun may not be as strong during the winter months in Canada, solar panels are still able to generate electricity, though at a potentially reduced capacity.

During the winter, the days are shorter, and the sun is lower in the sky, which can lead to less direct sunlight reaching the solar panels. This can affect the amount of electricity that the panels are able to produce. However, there are a few ways to maximize the efficiency of solar panels during the winter months.

Seasonal Sun Angles

One way to increase the efficiency of solar panels in the winter is to angle them towards the sun. In the Northern Hemisphere, the sun is lower in the sky during the winter months, so pointing the solar panels towards the south can help to maximize the amount of direct sunlight they receive. In Canada, the optimal angle for solar panels is usually around latitude plus 15 degrees. However, unless you have a dual-axis tracking system on the ground, this may not be possible due to the fixed nature of the racking on the roof.

Another way to improve the efficiency of solar panels during the winter is to keep them clean. Snow and ice can accumulate on the panels and block the sunlight, reducing their effectiveness. Regularly cleaning the panels, either by brushing them off or using a solar panel cleaning system, can help to keep them functioning at their best. We often have provided a service to customers and can safely clear the modules and make sure you’re producing as much electricity through-out the winter.

It’s also important to consider the type of solar panels being used. Some solar panels are more efficient at generating electricity in lower light conditions, such as during the winter months. These types of panels, known as “high efficiency” or “mono-crystalline” panels, are made from a single crystal of silicon and can capture more light, even on cloudy days. This is one of the main reasons we only provide mono-crystalline panels to our customers.

Despite the potential for reduced efficiency during the winter months, solar energy can still be a reliable and cost-effective source of electricity in Canada. Many homes and businesses in Canada have solar panel systems installed, and with the right equipment and maintenance, these systems can continue to generate electricity even during the winter months.

Production vs Generation

Overall, solar energy is a clean and renewable energy source that can be harnessed to generate electricity for homes and businesses. While the efficiency of solar panels may be reduced during the winter, with proper maintenance and the right equipment, they can still be a reliable and cost-effective source of electricity.
