  There are compelling evidences for the existence of a fourth degree of
freedom of neutrinos i.e. sterile neutrino. In the recent studies the role of
sterile component of neutrinos has been found to be crucial, not only in
particle physics, but also in astrophysics and cosmology. This has been
proposed to be one of the potential candidates of dark matter. In this work we
investigate the updated solar neutrino data available from all the relevant
experiments including Borexino and KamLAND solar phase in a model independent
way, and obtain bounds on the sterile neutrino component present in the solar
neutrino flux. The mystery of the missing neutrinos is further deepening as
subsequent experiments are coming up with their results. The energy spectrum of
solar neutrinos, as predicted by Standard Solar Models (SSM), is seen by
neutrino experiments at different parts as they are sensitive to various
neutrino energy ranges. It is interesting to note that more than $98\%$ of the
calculated standard model solar neutrino flux lies below $1MeV$. Therefore, the
study of low energy neutrinos can give us better understanding and the
possibility to know about the presence of antineutrino and sterile neutrino
components in solar neutrino flux. As such, this work becomes interesting as we
include the data from medium energy ($\sim 1MeV$) experiments i.e. Borexino and
KamLAND solar phase. In our study we retrieve the bounds existing in
literature, and rather provide more stringent limits on sterile
neutrino($\nu_{s}$) flux available in solar neutrino data.
