Dear Blueberry Bushes, How much sun is too much sun?

Zone 5b New Hampshire.

I’m considering putting a few blueberry bushes on the south/southwest side of my property. It’s the hottest part of the yard, right at the end of my property where the sun beats off the blacktop road pavement most of the day . The area starts getting sun around 11 and it’s in full exposure until sundown…I know blueberries like full sun but will this be too much?
