This article is way above my pay grade, but does show that Si panels 
create RF noise.  How much above the top frequency limit of 100Khz shown 
in the chart may or may not be a problem.  However, put enough panels 
together and perhaps it is.


It wouldn't seem to be too difficult to measure a plain panel with an 
E-field sensor or antenna on a spectrum analyzer.
