The most common of these is back-sheet failure. While the front glass sheet protects the solar cells from rain, hail, dirt and debris, the white or black plastic back-sheet is designed to protect the rear side of the cells from water, humidity and scuffs.
If the external force is so strong that it breaks the glass while also damaging the cells inside the solar panel, the consequences can be even more serious. Damage to solar cells directly impacts panel performance and efficiency. Cracks or breakages can cause uneven current distribution, reducing overall energy conversion efficiency.
Damage to solar cells directly impacts panel performance and efficiency. Cracks or breakages can cause uneven current distribution, reducing overall energy conversion efficiency. This damage also lead to hotspots and performance degradation, compromising the reliability and lifespan of the solar energy system.
For some models, there has been a spike in the number of cracked backsheets — layers of plastic that electrically insulate and physically shield the backsides of solar panels. The premature cracking has largely been attributed to the widespread use of certain plastics, such as polyamide, but the reason for their rapid degradation has been unclear.
When bypass diodes in solar panels are activated due to severe shading, they can dissipate some of the electrical energy as heat. This can lead to overheating if the diodes operate continuously under shaded conditions, increasing the risk of failure and often leading to hot spot formation and panel failure.
An example of solar panel back sheet cracking and delamination. In addition to the well-known PID and LID effects, panels can also suffer from more serious issues due to the breakdown of the encapsulant and protective layers that are supposed to protect the cells from the elements. The most common of these is back-sheet failure.
