The multipurpose JUNO Experiment located in China, whose central detector uses 20 kt liquid scintillator, is on the track to completion of its construction in 2023. Its primary goal is to determine the Neutrino Mass Ordering by leveraging its large target mass and the excellent energy resolution of 3\% at 1 MeV. The unique properties of JUNO position it to have a large potential for the real-time solar neutrino measurements. A sensitivity study is performed by considering all potential sources of backgrounds at various radiopurity levels, along with a full simulation of the detector response using reconstructed variables. Our results indicate that for the most of the background level scenarios, JUNO will be able to improve the current best measurements of $^{7}$Be, \textit{pep}, and CNO solar neutrino fluxes. Furthermore, JUNO has a potential to measure individually for the first time the rate of the two main components of the CNO neutrino flux, namely the $^{13}$N and $^{15}$O solar neutrinos. This article summarizes the strategy used for the estimation of the JUNO's sensitivity to $^{7}$Be, \textit{pep}, and CNO solar neutrinos above 0.45 MeV and presents the final results.
