Do solar panels have a manufacturing defect?
Fortunately, this is very rare, and usually, only 1 in 5,000 panels will suffer from a manufacturing defect. Defects are often associated with the constant drive to reduce costs, and not surprisingly, this is why lower-cost panels generally suffer more faults compared to panels from well-established premium solar brands.
What happens if a solar panel back sheet cracks & delamination?
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.
What are the most common problems with solar panels?
