Solar radiation pressure acting on a planet's surface is traditionally considered as a sun's mass correction to the Keplerian motion. For a solar-orbit satellite, because the area to mass ratio varies due to the orientation uncertainty of the solar panel, the orbital disturbance should be considered using disturbing theory. An analytic solution of a solar-satellite orbit disturbed by the solar radiation pressure is derived. The mean anomaly M is subjected to a secular perturbation, and there exist short-periodic disturbances on all Keplerian elements. By comparing the results with that of the sun's mass correction, we found out that the result obtained by traditional sun's mass correction implicitly uses a focus, which is the common mass centre of the sun and the correcting mass and which rotates along with the satellite related to the solar mass centre, as a reference of the orbital ellipse. The focus is also not an inertial reference point.
