  Over the past five decades, solar neutrino research has been pivotal in
driving significant scientific advancements, enriching our comprehension of
both neutrino characteristics and solar processes. Despite numerous experiments
dedicated to solar neutrino detection, a segment of the lower pp spectrum
remains unexplored, while the precision of measurements from the CNO cycle
remains insufficient to resolve the solar abundance problem determined by the
discrepancy between the data gathered from helioseismology and the forecasts
generated by stellar interior models for the Sun. The CYGNO/INITIUM experiment
aims to deploy a large 30 m3 directional detector for rare event searches
focusing on Dark Matter. Recently, in the CYGNUS collaboration, there has been
consideration for employing these time projection chamber technology in solar
neutrino directional detection trough neutrino-electron elastic scattering.
This is due to their potential to conduct low-threshold, high-precision
measurements with spectroscopic neutrino energy reconstruction on an
event-by-event basis driven by the kinematic. However, so far, no experiments
have been investigated on the feasibility of this measurement using actual
detector performances and background levels. Such a detector already with a
volume of O(10) m3 could perform an observation of solar neutrino from the pp
chain with an unprecedented low threshold, while with larger volumes it could
measure the CNO cycle eventually solving the solar metallicity problem.
