You might be surprised at how effective solar panels can be, even in colder climates. It’s not the cold that affects the solar system’s performance but rather a lack of sunlight. As long as sunlight is reaching the surface of the panels, they will continue to generate electricity. Let’s dive deeper into how different weather conditions impact the efficiency of solar panels so that you can make an informed decision.

What about extreme cold?

Cold weather shouldn’t impact solar panels much at all and extreme cold will simply affect its efficiency rather than make it stop working entirely. It’s not just the cold that does this, either. In fact, extreme heat can sometimes be even worse than the cold. So don’t just assume that the hotter the climate the better the solar system.

What about cloudy weather?

Again, cloudy weather isn’t going to make your solar panels stop working altogether, but it will reduce how much is absorbed by the panels. Cloudy weather reduces the amount of direct sunlight reaching your panels, which can decrease their efficiency. However, solar panels can still generate electricity from diffuse light—light that is scattered by clouds. While the energy output will be lower compared to a sunny day, your system will still produce power.

What about the rain?

Rain will not impact how well your solar panels work. In fact, the best thing about rain is that they’re just going to give your solar panels a good wash and help you in maintaining them and keeping them clear of debris. Heavy thunderstorms could, however, leave a lot of leaves and dirt behind so you’ll need to give them a clean once the storm is over.

What about the snow?

Thick snow will block the solar panels and stop them from working to their full potential. But the good news is that most solar panels have dark or reflective glass which helps to speed up the melting process. Solar panels are also usually at an angle which means they should slide off quite easily once melted.

A common misconception is that solar panels require heat to generate electricity. In reality, solar panels produce electricity from the sun’s light, not its heat. This means that as long as there is light, even if it’s cold, your panels will work. Interestingly, the most efficient conditions for solar panels are bright and cold days. The cool temperature helps the panels operate efficiently, while the abundant sunlight maximizes energy production. Extreme heat, on the other hand, can decrease the efficiency of solar panels as the PV cells can become less effective at higher temperatures.

Should you get solar if you live in a cold climate? Yes. Switching to solar has benefits no matter what climate you’re in, even if the conditions aren’t optimal. Speak to a solar installer to find out if solar is right for you!
