module testing

The use of POE as an encapsulant in TOPCon module construction could limit the effects of degradation on the module’s electricity generation.

The inclusion of a thicker aluminium oxide layer in TOPCon solar cells could provide superior resistance to UVID, according to UNSW.

Up to one-fifth of solar PV modules degrade 1.5 times faster than average, according to new research from the University of New South Wales.

Traditional PV inspection methods using direct current polarisation have proved unreliable in detecting certain issues. Researchers from Enertis Applus+ detail a new approach to defect detection aimed at improving the efficiency of PV system maintenance and performance analysis.

A total of 83% of module manufacturers have had at least one test failure in the Kiwa PVEL 2025 Module Reliability Scorecard, up from 66% a year ago.

Degradation issues identified in new cell technologies such as TOPCon and HJT underscore the importance of module stability as well as efficiency. Tom Kenning reports on the testing of next-generation modules and efforts to ensure their longevity in the field.

Modules will need to pass the 2021 version of the IEC 61215 testing series if they are to be approved by the CEC.

The Kiwa Group has published a report into PV module testing, which includes recommendations for a number of pass/fail module testing metrics.

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.
