Impact on Performance
The irradiance losses caused by near shading is quantified as ca. 3%.
Based on the crack distribution and types detected with electroluminescense, is it likely that the modules perform 2-4% less. Furthermore, these types of crack could eventually lead to inactive areas and higher power losses in the midterm.
Modules with inactive cell strings underperform 33% to 66% depending on the amount of affected strings. The extrapolation of the inspected sample to the whole system leads to a loss of 3% at system level.
