A re-reply, where did the other one go?
I had replied earlier, but it appears that the posting got lost somewhere.
You won't get printed reports on Solar Returns from a free charting service, at least not that I know of. Purchased software often has purchasable options which can include natal, relationship, progression, transit and return reports. These are about as helpful as the typical natal report is.
Tropical S/R charts are different from Sidereal or precession-corrected charts in their orientation, timing. The Tropical Solar Return can occur 10 hours or more earlier than the other form of Return for someone in their 30's, as much as a day later for someone in their 70's. This is because the Aries Point is regressing or moving backward at the rate of about one degree each 72 years. The end result is that the MC and ASC angles are quite different and the Moon position can differ by quite a few degrees.
At the risk of offending someone, I would say that Tropical Solar Returns are read similar to a natal chart reading with the focus being on the near term and not the life potential. In general, the methods of trying to define future events as to what they are and when (date) they will happen is the big perennial problems with Tropical S/R's.
Sidereal or precession-corrected Tropical S/R charts are read with the emphasis on angular natal and transiting planets (the Solar Return is basically a transit chart) and any natal angles that are at or near the S/R angles. There is a MC-Solar cycle that can be tracked using progressed angles that is highly useful for determining exactly what will happen when.
Again, you have to make a study of these methods in order to use them. And you have to decide what you are looking for from your Solar Return chart. If you want a broad picture of how you'll approach the areas of your life where strife and opportunities will occur, then choose the Tropical version. If you are looking for event definition and timing of events than choose the other type of chart. Dave
