Abstract: In this presentation we review the current status of standard solar models (SSMs) and the solar abundance problem. We show that the most recent generation of SSMs (B16) yields neutrino fluxes that favors solar models with high metallicity interiors. This is in agreement with helioseismic probes of the solar interior, which also favor high-metallicity solar models. For the first time, both solar neutrino fluxes and helioseismology point towards the same preferred solution. However, because available neutrino data refers only to fluxes coming from the pp-chain, this preference is not towards a certain solar composition but rather towards a given internal temperature profile. At this point, the degeneracy between solar composition and radiative opacities cannot be broken. Future CNO solar neutrino experiments are the most promising way of elucidating the answer to this conundrum. In this presentation, we also show that for cases where the detailed solar composition is not a critical factor, SSMs are an excellent framework over which to test non-standard physics in solar (stellar) interiors and a laboratory for particle physics regardless of the solar abundance problem.
