A solar return is read much like a natal chart. Many of the same principles apply. Tight orbs always have significance especially if there is many. As well, for a solar return degrees have very strong significance. Always look at the degrees of not only planets but the angles as well. Mid heaven, ascendant, etc.
If you do quarter returns for when the sun squares your natal sun and when it opposes, you can get more info as to when things will happen. And you’ll want to pay mind to the aspects and degrees on those charts as well.
