module testing

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.

Kiwa Group on why the integration of three PV inspection and QA businesses signposts the way forward for solar reliability testing.

A record of 53 manufacturers and 388 module types have been named “Top Performers” by Kiwa PV Evolution Labs (PVEL) in its 2024 Module Reliability Scorecard.

Authors from Kiwa PVEL explore how and why they have seen that the test results on individual bill of materials combinations vary.

Scientists from the University of New South Wales have found that TOPCon modules endure “significant degradation” in damp heat testing.
