Per an FCC engineer, most of the degradation (relative to a 'noise floor' a la an RSSI), has been from a continual increase of spectrum crowding. System-level degradation and component failures that contribute to increased emissions (and do not confuse defects with failures) are statistically isolated events, where no trend data is known to me. For power conversion equipment, failures typically cause an instantaneous change; that is, emissions degradations are seldom a gradual change.
Have seen some EMC reliability papers from PSMA/APEC and the Proceedings of Annual Reliability and Maintainability Symposium. The high priestesses of Bing and Google will graciously accept any submittal of your thoughts, hopes, and wishes to the ether.

I am trying to help decide if Electromagnetic Immunity/emissions could be a potential good topic of discussion at next year's NREL PV reliability conference. Does anyone have any field data, whitepapers, research info (not just for PV modules/inverters, but anything) to show possible degradation of EMC components/performance over time? Thanks in advance for sharing.
