Effects of soiling on PV module and radiometer performance

摘要: The question of "how much does the output PV modules and radiometers decrease due to soiling?" is often asked, but data are rarely available answer question. Related questions are: a) how effectively rain clean soiled devices; b) should be cleaned? Answers these essential predict module performance or accuracy (uncertainty) data. Results radiometer soiling from three independent applications presented in this paper. Data cover periods 16 months five years, results consistent for all applications.
