Using solar panels in the winter may seem like a pipe dream. Many are questioning whether solar panels can be used in winter due to the coming snow and cold. Although snow does not completely stop solar panels from producing electricity, it can significantly affect the efficiency and output of the system. If you want to maximize your system's potential, you'll need to be prepared for winter. You have a few options to help protect your investment and ensure it will last the winter.
The first step to winterizing your solar panels is to determine the angle of the sun. For some models of solar panels, a specific angle is required to ensure proper operation. If you don’t have tools to calculate this angle, it is best to speak with a panel manufacturer. Also, make sure to check the warranty on your panel. A solar panel manufacturer might not honor a warranty if the angle is not right.
Although the winter sun angle is identical to the summer sun angle it is slightly lower. The angle equals your latitude plus 10-15 degrees. Your solar panels should be installed at 45 degrees to the sun. Your panels might need an extra durable rating if you live or work in colder areas.
The solar panel with the best light-gathering ability is most likely the one that will produce the most power. While light snow is the best choice for cleaning solar panels, heavy snow can reduce their output.
It is tempting to get rid of the snow on your panels but you need to be careful. It could damage your panels, or worse, your safety. If you plan to remove the snow by yourself, you should wear sturdy shoes and a safe harness to avoid falling. For clearing snow off your panels, you will need to use a soft bristled brush.
Some snow loads are required for solar panels that can withstand winter. You will need to ensure that your system is in top condition throughout winter if you live in colder climates. While snow will not completely inhibit the system's ability to generate electricity, it can add weight and affect the efficiency.
The solar panel that makes the most power is that which produces the greatest amount of energy per hour. The best part is that you can actually make more power during the winter months than you did during the summer. It won't be as high in winter as it would be in summer, but it is still worth it.
While the sun doesn't shine as brightly in wintertime, there's plenty of sunlight to illuminate your panels. Additionally, ice and snow can hinder the ability of the system to produce electricity.
