Common solar panel defects.

Can defects of glass solar cells junction box silicon backsheet eva etc cause damage on solar panels or reduce the power output. Hotspots on panels are mainly caused by badly soldered connections or are a result of a structural defect in the solar cells. Regardless in which country your solar panels are produced solar panel defects occur on a regular basis. Hot spots are places on the panels which are overloaded and therefore become warm.

The payback performance of a solar pv systems is based besides fits and irradiation on the initial power output power degradation and the lifetime of the pv module s.
