The "tilt angle" is $\theta$. Scroll down to the bottom of the page. They give the equations.

I know elevation angle or tile angle for single unit. which varies from morning 9AM (-45 degree) to +45 degree @ 4pm
spacing between two stricture are 3200 mm,
height of panel or obstacle is h=1200 mm.
Question here is how to calculate D , D' and alpha new after implementing.

Code: Select all

 static float height=1200; static float D_max=3200;//d' here float phi_a = azimuth*M_PI/180; D_min= D_max*cos(180-phi_a); Angle=(atan(height/D_max)*(180/M_PI)); 
Here i can possible to upload excel sheet . to understand my concept
