  The combined effect of SFP and the non standard neutrino interaction (NSI) on
the survival probability of solar electron neutrinos (assumed to be Dirac
particles) is examined for various values of $\epsilon_{11}$, $\epsilon_{12}$
and $\mu B$. It is found that the neutrino survival probability curves affected
by SFP and NSI effects individually for some values of the parameters
($\epsilon_{11}$, $\epsilon_{12}$ and $\mu B$) get close to the standard MSW
curve when both effects are combined. Therefore, the combined effect of SFP and
NSI needs to be taken into account when the solar electron neutrino data
obtained by low energy solar neutrino experiments is investigated.
