Solar Panel in Pakistan are a module with special photocells that capture sunlight and convert it into energy. Solar panels can last up to 50 years, allowing you to power your home on your own. However, the main principle of operation of the panels is the generation of current under the action of the sun. What to do in the winter season? How does a solar station work in winter and is it possible to get enough electricity?

How efficient is the use of solar panels in winter
Solar panels only work when exposed to sunlight. Due to the fact that the duration of daylight hours in winter is reduced and the number of cloudy days is greater, the panels can no longer produce the same amount of energy. Depending on the region, the productivity of solar panels can drop up to 5 times. The further south your location is, the less noticeable the difference in the amount of electricity received will be.
For a better understanding, let’s take a standard set of electrical appliances that we use every day – a TV, a refrigerator, a computer, two or three lamps. In summer, no more than 1 kW of electricity is required to meet these needs. If you count, then these are 4 batteries of 250 watts. For the same task in winter, you will either need to increase the number of panels by 2 pieces or buy initially more powerful ones that will generate at least 2 kW.
How the panels work
The fact that solar panels need sunlight to work is true, but many are mistaken and believe that they produce more current in summer than on a winter day. The point of battery efficiency is to capture and convert sunlight, no matter what the temperature outside. On the contrary, if they overheat strongly at high temperatures above 25 degrees, then the efficiency decreases. Therefore, a bright sunny day with a low temperature is the ideal conditions for the panels to work, just the same in winter.
Which solar panels work best in winter
If we evaluate the performance of panels at different times of the year, then polycrystalline ones perform best. They are able to give greater efficiency in diffused light and in cloudy weather, when the rays make their way through the clouds.
This is due to their special structure, namely: silicon crystals are randomly oriented, that is, they, on the contrary, give 2-3% less efficiency on sunny summer days, and more than monocrystalline ones in winter or cloudy weather. It is also important to choose the right mounts for Solar Panel Suppliers in Pakistan, which will allow you to choose the right angle of inclination.
The ideal option for panels at any time of the year are modules that can process both infrared and ultraviolet radiation. This is a separate promising direction in the field of solar batteries, which has not yet been put on the conveyor and is not available for mass consumption. However, work is being done every day, which will allow launching such types of modules for sale in the near future and obtaining high efficiency even in winter.
