when you asked me what are the factors that are necessary to be examined in a chart of Solar Return, here are the following factor.
1) In which House of the natal chart lies the Ascendant of the SR;
2) In which House of the Solar Return chart exists a stellium (if any) of the SR;
3) In which House of the Solar Return chart is the Sun of the SR located;.
4) In which House of the Solar Return chart is Mars of the SR located;
5) Everything else, but far less.
