"The key to winning approval with Solas is to show that you are thoughtful and inclined to see shades of gray in the world. Declaring things to be simply black-and-white matters will earn Solas' disapproval quickly, but asking many questions and looking for more information will impress him. He prefers the thoughtful approach in most situations and does not approve of you claiming to be sent by Andraste in order to win alliances. You can improve Solas' opinion of you by finding elven artifacts and activating them in order to get a more accurate measurement of the strength of the veil. These are scattered around the world, but Solas will point them out to you when you are near them."
Some little decisions that are mentioned as approval are: Performing the Mythal temple ritual and accepting the alliance with Abelas.
**Note: There have been comments on how some of the choices have given different results. The guide seems to have made some errors here and there. PM me about any problems and I will edit them**
These are the only ones that count as change. The rest don't effect his approval meter
