We study the sensitivity of the HELLAZ and Borexino solar neutrino experiments on discriminating the neutrino species νe, ν̄e, νμ,τ, ν̄μ,τ, and νs using the difference in the recoil electron kinetic energy spectra in elastic neutrino-electron scattering. We find that one can observe a non-vanishing νμ,τ component in the solar neutrino flux, especially when the νe survival probability is low. Also, if the data turn out to be consistent with νe ↔ νμ,τ oscillations, a ν̄e component can be excluded effectively.
