  We present three-dimensional (3D) non-local thermodynamic equilibrium
(non-LTE) radiative transfer calculations for silicon in the solar photosphere,
using an extensive model atom that includes recent, realistic neutral hydrogen
collisional cross-sections. We find that photon losses in the SiI lines give
rise to slightly negative non-LTE abundance corrections of the order -0.01 dex.
We infer a 3D non-LTE based solar silicon abundance of 7.51 dex. With silicon
commonly chosen to be the anchor between the photospheric and meteoritic
abundances, we find that the meteoritic abundance scale remains unchanged
compared with the Asplund et al. (2009) and Lodders et al. (2009) results.
