  Neutrino-electron scattering experiments play a crucial role in investigating
the non-standard interactions of neutrinos. In certain models, these
interactions can include interference terms that may affect measurements.
Next-generation direct detection experiments, designed primarily for
dark-matter searches, are also getting sensitive to probe the neutrino
properties. We utilise the data from XENONnT, a direct detection experiment,
and Borexino, a low-energy solar neutrino experiment, to investigate the impact
of interference on non-standard interactions. Our study considers models with
an additional $U(1)$, including $U(1)_{B-L}$, $U(1)_{L_e-L_\mu}$, and
$U(1)_{L_e-L_\tau}$, to investigate the impact of interference on non-standard
neutrino interactions. We demonstrate that this interference can lead to a
transition between the considered non-standard interaction models in the energy
range relevant to both the XENONnT and Borexino experiments. This transition
can be used to distinguish among the considered models if any signals are
observed at direct detection or neutrino experiments. Our findings underscore
the importance of accounting for the interference and incorporating both direct
detection and solar neutrino experiments to gain a better understanding of
neutrino interactions and properties.
