Downside on sun radiation/ Renewable Power engineering

Calculate the angle made by beam radiation with the normal to a flat plate collector on May 1 at 0900 h (Local apparent time ). The collector is located in New Delhi (28°35’N, 77°12’E) It is tilted at an angle of 36° with the horizontal and is pointing due South.
Repeat the calculation for 1200 h ( Local apparent time )
