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.
The advancement of solar cell and module technology has meant ever larger, higher power modules are being manufactured, shipped and installed at increasing speeds, placing new importance on product testing and inspection. Here, Enertis explores the role of electroluminescence inspection throughout the supply phase.
