They may be getting too much sun but they might also be getting too much water. Hydrangeas grow best with 4 hours of morning sunshine and shade from hot afternoon sun. The flowers will age prematurely if your plant is getting too much sun. Yellowing leaves scattered throughout the plant can simply be a symptom of heat stress; yellowing leaves all over the plant usually indicates overly wet soil. When soil is saturated it can drive out oxygen and the roots can suffocate and then rot. Carefully assess the growing conditions, the soil and its drainage, and the amount of water you give your hydrangea. I think you'll be able to determine just why the leaves are turning yellow. Good luck with your hydrangea!
