Solar Energy generation is gradually gaining popularity in Pakistan as more individuals begin to realize the benefits that renewable energy has to offer. But while the concept of meeting energy needs through solar is quite simple, there are various myths around it with the most common being that solar panels cannot perform well in winters. Hence, we shall try to answer one of the most frequently asked questions regarding the performance of solar panels.
Do Solar Panels Perform Badly in Winters?
To answer this question, it is important to explain the mechanism on which the solar panels work. Most people believe that a hot sunny day will contribute to a higher energy generation than a cold sunny day. This is certainly not true. The good news is that the panels are powered by light, not heat, so they can easily continue to fuel industries, households, and workplaces irrespective of the increase or decrease in temperature.
Solar panels work on a simple mechanism. They absorb light energy from the sun and convert it into electrical energy. The inverter then converts DC energy to AC energy that can be fed into a grid, or can be used locally. The panels that absorb the sun’s energy are not sensitive to heat. This means that regardless of the temperature being high or low, the panels work equally well. In fact, high temperatures tend to diminish the panel’s capability. Blazing summers are harsher on the board and may cause frequent damage to the system. Therefore, cold sunny days are perfect for maximum solar output. However, during darker months, when there is shorter daylight, production of energy is proportionately lesser. Luckily, Pakistan is a country that enjoys adequate sunshine all year round and has a strong potential for solar power generation to meet its energy requirements.
