  As I have said many times already, the Sun's gravitational pull being
stronger than the Earth's is inconsequential. The Sun's gravitation is
affecting *both* the Moon and the Earth at the same time, as a whole.
They are both "falling" at the same rate. Thus it doesn't really matter
what this rate actually is (at least not at Earth's altitude).

  Think of it like this: At midday the Sun's gravitation effect on *you*
is stronger than the Earth's. However, that doesn't mean you are going to
be pulled out of Earth. (The reason is that the same gravitation is *also*
affecting the Earth.) Easier to understand it like this?
