I beg to differ !!!
The sun is still plenty energetic enough at 10-12 Ghz to
override weak satellite transmissions.
In fact the solar flux is measured at 10 Ghz...
Solar outages are not greatly worse on C band.
It WAS true that EIRPs at C band were kept lower at one time (to
protect the now mostly completely abandoned terrestrial C band microwave
telephone network which shares 3.7-4.2 Ghz with C band satellite) than
at Ku band, but that is less true today...
