The Right Ascension and Declination of the Sun at the summer solstice are 6h and +23.5 degrees, respectively. At the autumnal equinox, the Sun is found at RA=12h and Dec=0 degrees At winter solstice, the Sun is at 18h and -23.5 degrees. At the vernal equinox, the Sun is at 0h and 0 degrees.

I do not believe that the RA is undefined, since RA is measured from the vernal equinox, a point which moves across the sky. If I am not mistaken, the RA of the sun at summer solstice is 6 hours. The declination is +23.5 degrees.
