From memory the Sun emits energy with a mass equivalent of 4.26*10^6 tons per second assuming the photons average 2eV the number comes out at approximately 10^45
But I am prepared to have my arithmetic corrected.
The eagle eyed will note I made several corrections my memory of the Suns output and the mass equivalent energy of a 2eV photon were both wrong but at least my arithmetic was OK
