As a renewable energy specialist with extensive experience in the field of solar energy, I can provide a detailed explanation on how solar panels perform in different seasons.
First and foremost, it's important to clarify that the efficiency of solar panels is influenced by a variety of factors, including sunlight intensity, angle of incidence, and temperature. Contrary to the common belief that solar panels perform better in summer due to the heat, the actual reason for higher energy generation during this season is the longer daylight hours. The angle of the sun's rays also plays a significant role; in summer, the sun is at a higher angle in the sky, which means that the solar panels receive sunlight more directly, reducing the loss of energy due to reflection and absorption.
However, when it comes to the operating temperature of solar panels, cooler temperatures are generally more favorable. Solar panels are designed to operate at a standard test condition (STC) temperature of around 25°C (77°F). As the temperature rises above this point, the efficiency of the solar panels decreases. This is due to the fact that solar cells, which are made of silicon, can suffer from thermal losses when they get too hot. The hotter the solar cells become, the more electrical resistance they exhibit, which in turn reduces their ability to convert sunlight into electricity.
In winter, while the days are shorter and the sunlight is less intense, the lower temperatures can actually enhance the performance of solar panels. The reduced heat means that the solar cells can operate closer to their optimal temperature, thus maintaining or even slightly improving their efficiency. Additionally, the angle of the sun in winter can also be beneficial in certain regions, as the lower angle can increase the amount of sunlight that is absorbed by the panels.
It's also worth noting that the performance of solar panels can vary depending on their location and the specific type of solar technology used. For instance, some newer solar panel technologies are designed to perform better at higher temperatures, mitigating some of the losses that traditional panels experience.
In conclusion, while solar panels may generate more electricity in summer due to longer daylight hours and more direct sunlight, their efficiency can actually be higher in winter due to the cooler operating temperatures. It's a combination of these factors, along with the specific conditions at a given location, that ultimately determines the overall performance of solar panels throughout the year.

There is a common misconception that solar panels generate more energy in summer because of the heat associated with the season. However, the real reason for this seasonal energy boost is that summer day are longer, not hotter. Solar panels actually work more efficiently in cooler winter temperatures.
