  Bremsstrahlung of $W$ and $Z$ gauge bosons, or photons, can be an important
dark matter annihilation channel. In many popular models in which the
annihilation to a pair of light fermions is helicity suppressed, these
bremsstrahlung processes can lift the suppression and thus become the dominant
annihilation channels. The resulting dark matter annihilation products contain
a large, energetic, neutrino component. We consider solar WIMP annihilation in
the case where electroweak bremsstrahlung dominates, and calculate the
resulting neutrino spectra. The flux consists of primary neutrinos produced in
processes such as $\chi\chi\rightarrow \bar{\nu}\nu Z$ and $\chi\chi\rightarrow
\bar{\nu}\ell W$, and secondary neutrinos produced via the decays of gauge
bosons and charged leptons. After dealing with the neutrino propagation and
flavour evolution in the Sun, we consider the prospects for detection in
neutrino experiments on Earth. By comparing our signal with that for
annihilation to $W^+W^-$, we show that the detection prospects for the
bremsstrahlung annihilation channel are favourable.
