The large target, high scintillation light yield and good spatial resolution in all three cartesian directions concurrently allows also a high precision measurement of solar neutrino fluxes via elastic scattering. We studied the cosmogenic and radiogenic backgrounds affecting solar neutrino detection in a 100 tonne fiducial LAr TPC operating at LNGS depth. Such a detector has the potential to measure the CNO neutrino rate with 5~$σ$ sensitivity, and to significantly improve the precision on the measured $^7$Be and pep neutrino fluxes. ; Other ; Published by Deutsches Elektronen-Synchrotron, DESY, Hamburg
