Do Solar Panels Work In Winter?

A common misconception held by many people is that solar panels do not work in winter. Quite the contrary, low temperatures will instead increase the output of solar panels. But it is true that solar panels covered in snow in winter can affect power production.

Solar panels need sunlight to generate electricity, so if your panels are covered in snow, they will not generate electricity. Most modules are mounted at a certain tilt angle and the snow will slide off on its own, but this will take some time. You can also clear the snow by making a snow rake or similar snow removal tool, which usually does not damage the panels.

Cool, sunny weather is actually good for generating electricity from the modules.
Where there is a lot of snow, the panels can still produce a considerable amount of electricity. In fact, very cold weather and the reflective properties of snow are actually good for PV performance.

As long as the modules are not covered in snow, winter is actually good for generating electricity. Like most electronics, solar panels are more efficient in cold conditions than in hot conditions, making the most of every hour during the relatively short daylight hours in winter to generate electricity.

Tips for snow power generation.

1. Remove snow at the right time
You may need a tennis ball at this time. It is a good idea to use a tennis ball to bounce the snow off a tilted panel. Of course, you can also borrow other tools. This way you will find that your power generation system is twice as effective.

2. Install solar panels at a wide angle
This will reduce the rate of snow accumulation and save you the trouble of having to clear it from time to time. "In case you're debating whether to go for 30 degrees or 40 degrees, obviously 40 would be a better option." Pierce says.

3. Keep a small distance from the place when installing
Snow won't build up on the bottom as it slides down to slowly accumulate and cover the entire battery assembly.

It is normal for PV plants to produce less electricity in winter because the length of daylight becomes less in winter. But because of the low temperature in winter, it is conducive to photovoltaic power generation, and also plays a good role in protecting the service life. In addition, in winter we should pay attention to the maintenance of the power station and maintenance, pay attention to clean dust and snow.
