1) 'Delta V' is a vague parameter to me.
2) Associated with 'mass' it might mean 'volume,' which wouldn't vary.
3) Associated with perigee, it might me Kepplerian' 'velocity,' which continuously varies.

4) If you're acquainted with 'solar constant', then you already know that Earth's orbital eccentricity of 3%, between apogee and perigee, is already taken into account, which simplifies the calculation.
5) On short timescales, as we're considering, there would be no such thing as a 'new' perigee.
6) So we're just back to the stellar constant, divided by the square of the distance from the Sun's photosphere, to whatever distance we're interested in.
7) I performed a second mathematical proof, based upon the surface areas of the spherical energy fronts, and my results happened to be identical to what the Department of Physics, at The University of Chicago came up with.
