This paper suffers from conceptual difficulties and unjustified approximations that render its conclusions invalid. The influence of protons on electron capture by Be7 in the Sun is already included in the standard plasma screening correction to the density of thermal electrons at the Be7 nucleus needed for calculating the capture rate. Moreover, the approximation to the three-body wave function that underlies the entire argument of Belyaev, Tater, and Truhlík [Phys. Rev. C 75, 034608 (2007)] is not valid in the limit under consideration, namely when the electron and the Be7 nucleus are spatially coincident and the proton is some 30 000 fm away from the other two particles.
