  Dark matter captured by interaction with electrons inside the Sun may
annihilate via long-lived mediator to produce observable gamma ray signals. We
utilize solar gamma ray flux measurements from the Fermi Large Area Telescope
and High Altitude Water Cherenkov observatory to put bounds on the dark matter
electron scattering cross-section. We find that our limits are four to six
orders of magnitude stronger than the existing limits for dark matter masses
ranging between GeV to PeV scale.
