Degradation of flexible solar panels

What causes a solar panel to degrade?

Potential-Induced Degradation (PID): This happens when different components of the solar panel operate at different voltages, leading to voltage leaks. Age-Related Degradation: Over time, exposure to weather elements like rain, snow, and heat can cause wear and tear on the panels. The main causes of solar panel degradation include:

What is the degradation rate of solar panels?

The degradation rate of many solar panels can be as high as 0.7% per year. This can result in losses for manufacturers, as they must comply with warranties by providing new modules. The degradation of solar panels in the field can be long-term or short-term, depending on the mechanism involved.

How does aging affect solar panels?

Aging is the main factor affecting solar panel degradation, this can cause corrosion, and delamination, also affecting the properties of PV materials. Other degrading mechanisms affecting PV modules include Light-Induced Degradation (LID), Potential-Induced Degradation (PID), outdoor exposure, and environmental factors.

How much does a solar panel degrade a year?

This means that a solar panel’s power output will decrease by 0.5-0.8% each year compared to its initial rated output. However, the actual degradation rate can range from as low as 0.2% to as high as 1% annually, depending on the quality and materials used in the panel. To illustrate the impact of degradation, consider a 250-watt solar panel.
