We study the sensitivity of the HELLAZ and Borexino solar neutrinoexperiments on discriminating the neutrino species nu_e, anti-nu_e,nu_{mu,tau}, anti-nu_{mu,tau}, and nu_{sterile} using the difference in therecoil electron kinetic energy spectra in elastic neutrino-electron scattering.We find that one can observe a non-vanishing nu_{mu,tau} component in the solarneutrino flux, especially when the nu_e survival probability is low. Also, ifthe data turn out to be consistent with nu_e <-> nu_{mu,tau} oscillations, ananti-nu_e component can be excluded effectively.Comment: 24 pages, 7 figure
