  We consider searches for dark matter annihilation to monoenergetic neutrinos
in the core of the Sun. We find that liquid scintillation neutrino detectors
have enhanced sensitivity to this class of dark matter models, due to the
energy and angular resolution possible for electron neutrinos and antineutrinos
that scatter via charged-current interactions. In particular we find that
KamLAND, utilizing existing data, could provide better sensitivity to such
models than any current direct detection experiment for $m_X \lesssim 15$ GeV.
KamLAND's sensitivity is signal-limited, and future liquid scintillation or
liquid argon detectors with similar energy and angular resolution, but with
larger exposure, will provide significantly better sensitivity. These detectors
may be particularly powerful probes of dark matter with mass $\mathcal{O}(10)$
GeV.
