The sun will be coming from about 200 degrees, 70 degrees up at 2p, moving across the sky to 250 degree, 50 degrees up in 2 hours. You will be traveling at about 215 degrees. In the left window seat you may get a sliver of sun for the first 20 minutes or so, but it will be up high. So your left arm may get a little warm.

You should be good after that.
