We have evolved a series of thirteen complete solar models that utilize different assumed heavy element compositions .
Models that are based upon the heavy element abundances recently determined by Asplund et al .
( 2005 ) are inconsistent with helioseismological measurements .
However , models in which the neon abundance is increased by 0.4-0.5 dex to \log N ( { Ne } ) = 8.29 \pm 0.05 ( on the scale in which \log N ( { H } ) = 12 ) are consistent with the helioseismological measurements even though the other heavy element abundances are in agreement with the determinations of Asplund et al .
( 2005 ) .
These results sharpen and strengthen an earlier study by Antia & Basu ( 2005 ) .
The predicted solar neutrino fluxes are affected by the uncertainties in the composition by less than their 1 \sigma theoretical uncertainties .
