Solar Module Performance Degradation

Solar module degradation is the decrease in the performance of solar modules. While solar modules are designed to last for decades, their performance can be affected by a variety of factors. Here are the top 10 reasons for solar module degradation:

1. Age: Solar modules have a finite lifespan, and as they age, their performance will naturally decline. The exact lifespan of a solar module depends on the type and quality of the module, but most modules are expected to last for 25-30 years.
2. UV radiation: Solar modules are exposed to UV radiation from the sun, which can cause them to degrade over time. This is especially true for modules that are not properly coated or protected from the sun's rays.
3. Temperature fluctuations: Solar modules are designed to work within a specific temperature range, and extreme temperature fluctuations can cause them to degrade. For example, modules that are exposed to extremely hot temperatures may not perform as well as those that are kept in a cooler environment.
4. Moisture: Solar modules are designed to be weather-resistant, but they can still be affected by moisture. If panels become wet or damp, they may not perform as well as they should.
5. Dust and dirt: Dust and dirt can accumulate on solar modules, which can reduce their efficiency. Regular cleaning and maintenance can help prevent this type of degradation.
6. Hail and other forms of physical damage: Solar modules are built to withstand some degree of physical damage, but they can still be damaged by hail, falling debris, or other impacts. This type of damage can reduce the performance of the modules.
7. Electrical problems: Solar modules are connected to a system of wires and inverters that can also experience problems. If there are issues with the electrical components of the system, the performance of the modules may be affected.
8. Poor installation: Solar modules must be properly installed in order to work efficiently. If the modules are not installed correctly, they may not perform as well as they should.
9. Manufacturing defects: In rare cases, solar modules may be defective due to manufacturing issues. This can cause them to degrade more quickly than expected.
10. Shading: Solar modules rely on direct sunlight to generate electricity, so any shading that occurs on the modules can reduce their performance. This can be caused by trees, buildings, vegetation or other objects that block the sun's rays from reaching the modules.

By understanding the potential causes of solar module degradation, you can take steps to minimise their impact and ensure that your solar modules are performing at their best for as long as possible.
