What Is Solar Panel Degradation?

As a solar company, SolarGuru Energy is often asked about the degradation rate of solar panels and how it can affect their lifespan and performance. The degradation rate of a solar panel refers to the decrease in performance over time, and it is an important factor to consider when investing in solar energy. Here are some key factors that can affect the degradation rate of solar panels:

Quality of the panels:

The quality of solar panels can have a significant impact on their degradation rate. High-quality panels are typically more durable and have a lower degradation rate, while lower quality panels may degrade faster. It is important to choose high-quality panels from reputable manufacturers to ensure a longer lifespan and better performance.


Environmental factors:

Environmental factors can also affect the degradation rate of solar panels. Exposure to extreme temperatures, humidity, and other weather conditions can accelerate the degradation process. Solar panels that are exposed to harsh conditions may degrade faster than panels that are protected from the elements.


Maintenance and cleaning:

Proper maintenance and cleaning of solar panels can also affect their degradation rate. Dust, dirt, and other debris can accumulate on the panels and reduce their efficiency, leading to a faster degradation rate. Regular cleaning and maintenance can help keep the panels operating at their best and extend their lifespan.


Age of the panels:

The age of solar panels is also a factor in their degradation rate. As solar panels age, their performance tends to decline. However, the rate of degradation can vary depending on the quality of the panels and the environmental factors they are exposed to. High-quality panels that are well-maintained and protected from harsh conditions may degrade slower than lower quality panels that are exposed to extreme conditions.


Warranty and insurance:

Finally, the warranty and insurance coverage of solar panels can also affect their degradation rate. Many solar panel manufacturers offer warranties that cover the performance and degradation of the panels, and some homeowners may also choose to purchase insurance to protect against any potential issues. This can provide peace of mind and help protect the investment in solar panels.


In conclusion, the degradation rate of solar panels is influenced by a variety of factors, including the quality of the panels, environmental factors, maintenance and cleaning, age of the panels, and warranty and insurance coverage. SolarGuru Energy can help homeowners understand the degradation rate of solar panels and choose panels that will meet their needs and budget, ensuring a long lifespan and optimal performance.
