Mahmood, I'm afraid you will need to combine calender/clock math and tracking to optimize this.

Well why do I need to combine the two? I think the calender/clock math on its own is accurate enough isn't it?
Since we muslims know the sun rise and sun fall times all over the year then it will be no problem estimating sun position by calender. I guess the sun will be moving with constant speed all the day. and as I know where the east and west are it is just a matter of moving the dish periodically ( Like a clock)
Sun tables would be stored in 8052 and simple math to estimate position will be adequate with RTC.
This way I'm still left with 1 problem which is sun angle throughout the year.
May be Kai's equation above would solve this problem.
