We compute the energy spectrum of high-energy (0.1-10 GeV) neutrinos produced by the annihilation of supersymmetric (SUSY) cold dark matter trapped in the sun. We compare this spectrum to the spectrum of atmospheric neutrinos and find that in the direction of the sun the solar flux of neutrinos can exceed the atmospheric background for neutrino energies Eν >~ 1 GeV, and are as much as a factor ~ 30 above background for energies Eν ~ few GeV. We discuss these signatures for standard SUSY relics as well as for superstring relics.
