TOPCon solar modules show signs of accelerated degradation, which undermines the long warranties promised by many manufacturers, according to new findings from German researchers.

Researchers have called for enhanced international standards to detect ultraviolet-induced degradation (UVID) in PV modules after identifying “severe” levels of the problem in operational n-type panels.             

Greater awareness of UV light used to test solar cells could result in faster, more efficient assessments of long-term performance.

Kiwa PVEL examines the ultraviolet-induced degradation (UVID) results on n-type technology from its latest PV Module Reliability Scorecard.

The solar manufacturing and module purchasing community met in Napa to answer the question of 'what next?' for module supply in uncertain times.

In this year’s ultraviolet-induced degradation (UVID) testing, engineering advisory and test services provider Renewable Energy Test Center (RETC), has noticed that 40% of modules tested have returned with a red-flag result.
