Most neutrino mass extensions of the standard electroweak model entail nonstandard interactions which, in the low-energy limit, can be parametrized in term of effective four-fermion operators nu(alpha)nu(beta)ff. Typically of subweak strength epsilon(alpha beta)G(F), these are characterized by dimensionless coupling parameters epsilon(alpha beta), which may be relatively sizable in a wide class of schemes. Here we focus on nonuniversal flavor-conserving couplings (alpha=beta) with electrons (f=e) and analyze their impact on the phenomenology of solar neutrinos. We consistently take into account their effect both at the level of propagation, where they modify the standard Mikheev-Smirnov-Wolfenstein behavior, and at the level of detection, where they affect the cross section of neutrino elastic scattering on electrons. We find limits which are comparable to other existing model-independent constraints.
