What causes a solar panel to fail?

They found that the most common causes of early failure are junction box failure, glass breakage, defective cell interconnect, loose frame, and delamination. A study by DeGraaff on PV modules that had been in the field for at least 8 years estimated that around 2% of PV modules failed after 11–12 years.
