We study the effect of the nonresonant, vacuum oscillationlike neutrino flavor conversion induced by nonstandard flavor changing and nonuniversal flavor diagonal neutrino interactions with electrons in the Sun. We have found an acceptable fit for the combined analysis for the solar experiments total rates, the Super-Kamiokande energy spectrum and zenith angle dependence. Phenomenological constraints on nonstandard flavor changing and nonuniversal flavor diagonal neutrino interactions are considered.
