The Weakly Interacting Massive Particles (WIMPs) so far remain one of the most popular candidates for dark matter. If captured gravitationally inside the core of the Sun, these WIMPs may produce high energy neutrinos as the end product in case they undergo self annihilations at the solar core. In this work, we address the detectability of such neutrinos at the proposed KM3NeT detector. Upper bounds of the detection rate for such neutrinos at KM3NeT are computed for the case of a generic dark matter scenario and also when specific models for particle dark matter are chosen. In this work, upper bounds of muon event rates for different annihilating dark matter masses are computed for each of the cases of dark matter annihilation channels (e.g. $b\bar{b}~, W^+W^-, Z\bar{Z} $ etc). Using these computed upper bounds, the dark matter-nucleon scattering cross-sections are estimated for different dark matter masses. These are then compared with the experimental upper bounds of dark matter-nucleon cross-sections from direct dark matter detection experiments such as LUX, XENON1T, ArDM etc.
