I didn't check your files, but maybe this help you:
solar radiation is often measured in solar time, not in local time.
if you treat solar time measurements as local time data, the position of sun
doesn't fit to the measurements (example: values >0 W/m2at times when the
sun is down).  
-> use param. 9 in TYPE 16.
