Other schools have access to good club programs as well so I am not sure it is the club programs unless the ones in the Wando area are better than the ones in Columbia, Greenville or Charlotte/York County.
Coaching is certainly a big factor. Perhaps Coach Champ is the Phil Jackson of soccer coaches.
And size is certainly a factor. Especially when you look at the dynamics of how school soccer works.
High school soccer is dominated by club players. And club players require parents who are able to make the money and time commitment needed for their children to be successful. That also means that those parents tend to be better off and are able to pick and choose where they want to live, often living in places with better schools.
That is why the best programs in the state are dominated by up scale suburbs like Fort Mill, Mt Pleasant, Lexington, Mauldin, Taylors (Eastside) Hilton Head etc. The difference of course being that Mt Pleasant is much bigger than these other suburbs and you only have one high school.
So Wando has a combination of both the right demographics and you are much bigger than anyone you are competing again. That combination is why you are so dominant year after year.
Build a second school in Mt Pleasant and split Wando in half and you will have two good soccer programs, but you will probably not dominate the state like you do now.
