  We assess the prospects for indirect detection of Weakly Interacting Massive
Particles using a large Liquid Argon TPC detector. Signal events will consist
of energetic electron (anti)neutrinos coming from the decay of $\tau$ leptons
and $b$ quarks produced in WIMP annihilation in the core of the Sun. Background
contamination from atmospheric neutrinos is expected to be low, thanks to the
superb angular resolution and particle identification capabilities provided by
the considered experimental set-up. We evaluate the event rates predicted for
an annihilating WIMP as a function of its elastic scattering cross section with
nucleons. This technique is particularly useful for WIMPs lighter than
$\sim100$ GeV
