Solar Panel Degradation Curve and the Causes

Exposure to UV rays and adverse weather conditions are causes of solar panel degradation. Over time, solar panels experience a decrease in performance due to various factors.

This degradation follows a specific curve, known as the solar panel degradation curve. The rate of degradation differs depending on the quality of the panels, with high-quality panels degrading at a rate of around 0.5% per year.

This degradation impacts savings by reducing the overall energy production of the panels. As the panels degrade, their efficiency decreases, resulting in a lower output of electricity. This means that over time, the panels generate less energy, leading to decreased savings on electricity bills.

Understanding the solar panel degradation curve and the causes is crucial in maintaining and maximizing the lifespan and efficiency of solar panels, ultimately ensuring long-term savings.

Light-Induced Degradation

Light-induced degradation, specifically direct light-induced degradation (DLID) and UV light-induced degradation (UVID), can reduce the efficiency of solar panels by 1-3% within the first 1,000 hours of operation. This degradation occurs as a result of the interaction between the crystalline silicon cells in the panels and the surrounding environment.

Over time, exposure to sunlight and UV rays can lead to a decrease in the performance of solar panels. Each year, solar panels experience a small decrease in efficiency, typically ranging from 0.7% to 0.8%. This annual degradation adds up over time and can significantly impact the overall output of the panels.

It is important to consider the degradation factor of solar panels when assessing their long-term performance and savings potential. Regular maintenance and monitoring can help minimize degradation and ensure optimal efficiency.

Potential-Induced Degradation (PID)

Potential-Induced Degradation (PID) can occur when different components of a solar panel operate at varying voltages, leading to voltage leaks and reduced electricity sent to the inverter.

This phenomenon does not affect every solar panel and is caused by a disruption in voltage due to incompatible materials. To understand the impact of PID on long-term savings, it is crucial to consider the degradation rate of solar panels.

By analyzing data from various manufacturers, it has been found that high-quality panels experience a degradation rate of around 0.5% per year. However, with the presence of PID, this rate can increase significantly, resulting in even lower energy output.

To illustrate the potential impact of PID on savings, let’s take a look at the table below:

YearOriginal Output CapacityOutput Capacity with PID
1350 watts320 watts
5325 watts280 watts
10300 watts240 watts
15275 watts200 watts
20250 watts160 watts

As you can see, over a 20-year period, the presence of PID can result in a significant reduction in energy output. This reduction directly impacts your long-term savings as you receive less electricity from your solar panels. Therefore, it is crucial to choose high-quality panels and ensure proper installation to minimize the risk of PID and maximize your savings.

Age-Related Degradation

To minimize the effects of age-related degradation on your system, regular maintenance and cleaning are essential.

As your solar panels age, they are exposed to various elements such as heavy rainfall, snowfall, ice, and high temperatures. These factors can lead to degradation over time, resulting in a decrease in efficiency.

The crystalline silicon in the panels may harden, causing microcracks, damage to the seal, and shadowing, all of which reduce efficiency. Frame corrosion and cell contamination are also common issues.

By implementing regular maintenance and cleaning schedules, you can prevent or mitigate these issues. Proper installation techniques, using high-quality materials and components, and applying protective coatings or films can also help minimize degradation.

Regular monitoring and maintenance will ensure that your solar panels continue to perform optimally and provide you with the maximum benefits over their lifespan.
