I am studying the shadow casts by buildings throughout the year and I noted that during certain days of the year the sun is at the wrong position for location 14.5N, 121E and UTC+8:00. At this location, the sun should always be at the south of the building casting shadow to the north side. I noted that at 12:00NN of 4/29 the sun is above the building and no shadow is cast on the ground. Before this day, the sun is at the south side as it should be. After 4/29 the sun starts to move north of the building casting shadow to the south side ground. This occurs until 8/14 where the sun is again above the building. From this day onward, the sun moves to the south.
I uploaded a pdf file of the screen captures showing the above shadow positions.

My question is if there is any adjustment I can do to correct this. Any advice or guidance is highly appreciated. Thanks.
