Here it is:

$ guix package --list-installed | grep guix
guix    0.12.0-7.aabe    out   
/gnu/store/24fa9898h2aa7k7fcbp67kwrwgrxlgi5-guix-0.12.0-7.aabe
$ env | grep GUILE
GUILE_LOAD_PATH=/home/sirgazil/.guix-profile/share/guile/site/2.2
GUILE_LOAD_COMPILED_PATH=/home/sirgazil/.guix-profile/lib/guile/2.2/site-ccache:/home/sirgazil/.guix-profile/share/guile/site/2.2
$ find -L $(env | grep GUILE | cut -d = -f 2 | tr : '\n' | sort | uniq)
-name packages.scm
$

So, guix modules are available in ".guix-profile/share/guile/site/2.0"
but not in ".guix-profile/share/guile/site/2.2".

No. If I install guile 2.0.14, I can load guix modules just fine.
