Do solar panels work in winter?
Of course they do. To generate energy, the panels need light, not high temperatures. On the contrary, the heat outside reduces the efficiency of solar panels. The best option is low temperature and bright sun. Read on to find out what other nuances of solar panels in winter are important to know.
How they work
Solar panels are modules with photovoltaic cells that capture sunlight and convert it into electricity. How do solar panels work in winter and is it possible to get enough electricity with their help?
The panels work only when they are exposed to sunlight. As the day becomes shorter in winter, the performance of solar panels decreases. On the territory of Ukraine, this decrease occurs on average by 2-3 times. The further south you live, the less noticeable this difference will be.
How much energy do you need in winter?
For example, you have a standard set of electrical appliances: a TV, a refrigerator, a laptop, and several lamps. For them to work in the summer, you need no more than 1 kW of electricity (about 4 batteries of 250 W each). In winter, you will need at least 2 kW of electricity to meet the needs of your home.
Important conditions for the operation of solar panels in winter are to keep them free of snow and dirt. If the modules are covered with snow, they will not be able to work at all.
How to optimize the operation of solar panels in winter
Panel manufacturers make sure that they work in different conditions. For example, some models of solar panels can withstand even 2 meters of snow and temperatures down to -60°C. That is, their capacity is higher than the critical conditions of Ukrainian winters.
Tips for preparing for the cold season
- Change the angle of inclination. In order for solar panels to work as efficiently as possible in winter, it is important to change the angle of inclination. The optimal angle is approximately 10-15 degrees. During heavy snowfalls, the panels can be installed vertically so that snow does not interfere with energy generation. However, the panels can be installed at a universal angle that is suitable for any time of year. Consult our manager about these and other installation details.
- Take care of cleaning the solar panels in winter (if possible):
- Hose off the snow (if the air temperature is not too low).
- Sweep the panel.
- Fun way: buy Nerf blasters. A light ball won’t break the panel, but it will create vibrations that will cause the snow to melt. You will also have fun.
However, when cleaning solar panels, do not use harsh brushes or detergents that can damage the surface.
Debunking myths
It is said that solar panels are inefficient in winter because of the short day. This is not true. The innovative technologies that the panels are equipped with help them to cope very well with the tasks of alternative energy even in the cold season.
Another myth: the best period for solar panels is summer. This is not true. The most efficient period for panels is the off-season.
