Thank you André for your reply. I mean only 2-axes tracking ... sorry for using wrong sentence. I am using free version of PVsyst v-5.60. In which I go through >> Tools >> Solar tool box >> Tables / graphs of solar parameters >> Clear day multi orientation. And I get table with different tilt angles and different azimuth angles. But I need only normal to the plane solar radiation (with tilt angle = 50º as normal plane to the radiation), I mean only 1 column with solar radiation normal (= 50º) to the surface. How is it possible with PVsyst. Please guide. Thank you.
