  Solar neutrinos interact within double-beta decay (\BB) detectors and
contribute to backgrounds for \BB\ experiments. Background contributions due to
charge-current solar neutrino interactions with \BB\ nuclei of $^{76}$Ge,
$^{82}$Se, $^{100}$Mo, $^{130}$Te, $^{136}$Xe, and $^{150}$Nd are evaluated.
They are shown to be significant for future high-sensitivity \BB\ experiments
that may search for Majorana neutrino masses in the inverted-hierarchy mass
region. The impact of solar neutrino backgrounds and their reduction are
discussed for future \BB\ experiments.
