Well, one of our painted solid wood doors literally had the finish baked
right off it in little over a year. The heat also shrank some of the
crossmembers to the point where there were gaps you could see through. The
door we have now (solid oak) I refinished at the end of last summer using
a
a high quality UV resistant outdoor stain and a UV outdoor poly top coat.
It's already flaking off.

I do not want to be painting doors every year.

Take the new door to a body shop and get an automotive paint on it. Cars
sit in the sun and last a long time compared to house paint.
