I had mine in just 4-5 hours of direct inland 100f+ dry, low humidity sun, and they hated it.
If you are near the coastline, I bet they could be full sun in a year or two from whip size with decent growth. They really struggled late in the season with salt / mineral build up on the roots and would defoliate way early due to this. When they got to be reasonably well established, about 6' tall, they became a little stronger. It takes a long time to get them going.
