Protecting solar panels from snow

There is still a myth in society that owners of solar panels do not like winter. And this makes sense, because the days are shorter, the sun’s rays Shine with less intensity, more cloudy days, and these factors affect the performance of solar power plants. In winter, there is another, at first glance, unpleasant factor; precipitation. Especially our country suffers from heavy snowfall every year and almost every year breaks records for maximum indicators.

Snowfalls cover the north countries every winter and cause a certain amount of trouble to owners of solar panels. How much this problem prevents solar power plants from working, we will tell you now. We will also give recommendations for cleaning solar panels from snow.

Features of operation of solar panels in winter

Winter is not the best time for solar panels to work. In the introduction, we have already mentioned a number of reasons that prevent solar power plants from working at full capacity. If we take the average data, solar panels generate about 4 times less electricity in winter than in summer. Statistics are not very impressive, and even more so for making a profit. But it is worth noting that even in winter, solar panels work every day and every minute in the daytime.

Of course, clouds and precipitation reduce the amount of rays that fall on solar panels, but they are all there. Solar power plants are designed to operate in harsh conditions, even at low temperatures, or under a roof of snow. High-quality solar panels will withstand wet and cold weather to generate free electricity.

Whether the snow is a hindrance to solar panels?

We can say unequivocally and confidently that snow reduces the performance of solar panels by about 20-30 percent. But an important condition for this figure is the amount of precipitation. Just imagine that about 1-1. 5 m of snow fell, then the productivity will be much less. Of course these figures are an anomaly for our country, but long lines sometimes more. The snow seems to filter the sun’s rays and does not pass part of the panel. What to do in such situations?

Clean snow from solar panels is necessary if there is enough snow and it can be done safely for health.

First, the solar panels are installed at an angle, and if the snow is heavy, and it is very cold outside, the snow will take off from the solar panels on its own. This happens in 70% of snow precipitation on solar panels. There are also dynamic solar panel systems that can set the required angle for self-cleaning in winter.

Secondly, when solar panels work, they are heated to a plus temperature. This means that the snow itself will melt after some time of operation of the solar panels. 6-10 inches of snow to bring the afternoon he has to fade on their own. If the weather does not help You at all, then of course you need to independently intervene in the cleaning, or hire people to do it.

Third, you can buy cleaning tools in advance. This is usually a brush with a long stick, and various attachments. You can easily and quickly clean snow from solar panels in winter using these kits. The handle usually has the ability to decompose by 2-3 meters, which makes it easy to clean the solar panels from snow even on the roof.
