We present a generalization of the resonant neutrino conversion in matter, including a random component in the matter density profile. The study is focused on the effect of such matter perturbations upon both large and small mixing angle MSW solutions to the solar neutrino problem. This is carried out both for the active-active νe \ra νμ,τ as well as active-sterile νe \ra νs conversion channels. We find that the small mixing MSW solution is much more stable (especially in δm2) than the large mixing solution. Future solar neutrino experiments, such as Borexino, could probe solar matter density noise at the few percent level.
