I discuss the results of a standard fit of all solar data performed with an improved statistical analysis: the Dc²-cut gives a good approximation of Feldman-Cousins confidence regions, but the goodness-of-fit is significantly lower than usually reported. This motivates a non-standard analysis. Two of the many ingredients of a standard fit could be not completely safe: by relaxing solar model predictions or the error on the Homestake experiment we find non-standard oscillation patterns. I discuss how new experiments (SNO, Kamland, Borexino) can eventually recognize them and test solar models.
