  Since the end of the eighties, in response to a reported increase of the
total neutrino flux in the Homestake experiment in coincidence with solar
flares, neutrino detectors have searched for signals of neutrinos associated
with solar flare activity. Protons which are accelerated by the magnetic
structures of such flares may collide with the solar atmosphere, producing
mesons which subsequently decay, resulting in neutrinos at O(MeV-GeV) energies.
The study of such neutrinos would provide a new window on the underlying
physics of the acceleration process. The sensitivity to solar flares of the
IceCube Neutrino Observatory, located at the geographical South Pole, is
currently under study. We introduce a new approach for a time profile analysis.
This is based on a stacking method of selected solar flares which are likely to
be connected with pion production. An initial approach towards a neutrino
search using the current IceCube experiment as well as first efforts to improve
the detection efficiency in the future are presented.
