Global transition towards sustainable energy sources demands a holistic assessment of how external parameters influence the efficiency of solar power systems. Of these, temperature is important as it influences the overall performance of solar panels. Thus, understanding the impact of temperature on solar system efficiency is vital for maximizing the performance and output of solar energy systems. Solar panels are most efficient in moderate temperatures, but their efficiency can drop significantly in hot or cold environments. However, there are certain ways through which you can keep a check on your Solar Power Panel Efficiency.

 

Factors That Affect Solar Panel Efficiency:

A variety of factors can impact solar performance and efficiency, including: Temperature: It is worth noting that changes in the temperature directly impact solar PV efficiency. Solar panels operate best at ambient temperature i.e. around 77 degrees Fahrenheit (25 degrees Celsius). Higher temperatures reduce the efficiency of solar panels. This is because semiconductor material, which is usually sensitized to heat, is used for making solar cells. Sunlight: Solar panels efficiency is also influenced by how much sunshine they get. Solar energy systems are most productive when they receive direct sun rays, however, they are also capable of producing energy in indirect sunlight or on cloudy days. Orientation and Tilt: Solar system efficiency is also influenced by their orientation and tilt. In northern hemispheric countries like India solar panels should face south, and be at the same angle as the latitude of the installation site. This would ensure panels get as much sunlight as possible. Dust, Snow, and Debris: Dust, snow, or debris can significantly reduce solar panel efficiency. Cleaning and regular maintenance of solar panels are crucial in ensuring the proper operation of solar panels. Panel Age: The solar power panel efficiency keeps degrading gradually with each passing year. However, the degradation rate is very slow, and good solar panels are expected to last for at least 25-30 years. Shading: Solar power systems can also lose efficiency due to shading. Thus it is recommended not to allow such things as trees, buildings, or any other object to shade solar panels.

How Temperature Affects Solar PV Efficiency:

A solar panel system is primarily made of semiconductor material. Due to higher temperatures, the electrons of the semiconductor material move more, and hence, it leads to higher power losses. On the contrary, the conductivity of the materials decreases in colder temperatures, which results in an improved performance. A solar panel has a temperature coefficient that shows its reduction in efficiency per degree centigrade rise. It usually ranges from -0.2%/°C to -0.5%/°C. Therefore, it can be concluded that for every one degree Celsius rise and increase in the temperature, the solar system efficiency reduces between 0.2% to 0.5% as well.

Mitigating the Effects of Temperature on Solar Panel Efficiency:

Several things can be done to mitigate the effects of temperature on solar panel efficiency, including: Choosing the right solar panels: One can find different kinds of solar panels in the market with some being much more capable of tolerating high temperatures. While selecting solar panels, however, one must take into account the temperature coefficient plus the climate that characterizes the installation area. Installing solar panels in a cold location: It is important to install solar panels in a cold area free of direct heat exposure from asphalt or concrete. However, if it is possible, then, solar panels should be mounted on a north-facing roof or at least beneath a heat shade structure. Using solar panel cooling systems: There are several solar panel cooling systems in the market today. These technologies facilitate the cooling of the solar panels and eventually improve the energy yield per m².

Comparing Solar Efficiency in Hot and Cold Environments:

In hot regions, solar panels are typically less efficient than in places with colder temperatures. The temperature coefficient of solar panels is normally a negatively signed number, meaning that they become less efficient as the ambient temperature rises. For example, if a solar panel has a temperature coefficient of -0.4% per degree Celsius, its efficiency will be 4% lower in a hot environment with a temperature of 40 degrees Celsius than in a cold environment with a temperature of 20 degrees Celsius.
