Solar power plants are becoming increasingly popular as a clean and renewable energy source.

However, like any technology, there are certain factors that can cause performance degradation.

Here are the most common causes of performance degradation in solar power plants:

1. Module degradation:

This includes potential-induced degradation, soldering in modules and connection boxes, back sheet and thin film issues.

The quality of materials used in manufacture and the manufacturing process can affect the degree of degradation.

2. UV exposure:

Over time, solar cells experience wear and tear from exposure to UV rays which can cause performance declines.

3. Weather cycles:

Adverse weather conditions can also contribute to performance degradation.

4. Back-sheet failure:

The most common degradation seen in panels is back-sheet failure.

The back sheet is usually made of polyvinyl fluoride films and protects the solar cells from dust, hail, rain and debris.

5. Microcracks:

Microcracks develop on silicon of the solar cells due to the thermal cycling process.

These cracks can reduce the module operating voltage.

6. Aging of PV system components:

Energy losses and performance degradation are caused due to the aging of PV system components and other factors such as wire corrosion, water ingress, and lightning strikes.

7. Poor installation:

Faulty installation or maintenance can lead to performance degradation or even complete system failure.

 conclusion,

while solar power plants have numerous benefits, it is important to maintain and monitor them to avoid performance degradation.

By addressing these common causes, operators can ensure that the system runs properly and continues to provide clean energy efficiently.
