[RE-wrenches] Spacing between solar arrays

[Joel Davidson]

Hello William,

Thanks for the offer, but I'm limited to 15 MB.

Your spreadsheet is nice and simple (if I'm using it correctly).
160-inch panel length
flat roof
10 degrees panel tilt
sun 30 degrees altitude
sun 180 degrees azimuth
= 205.6 inches inner-row space (approx 1 to 1.3 ratio).

FYI - California rebate programs suggest or require 1 to 1.5 ratio for a measure of safety.

  Do you mind if I send you a 97 mb animation?

    Ken,
     
    Thank you. This website and software gives the sun altitude and azimuth. I seem to recall 3D graphic dynamic software where you input the site longitude and latitude, solar panel tilt angle and the north side height and the result would be a shade pattern shown for each hour. Does anyone have such a program?
     
    Best regards,

        Wrenches,
         
        Someone posted a website or calculation for determining the spacing between solar arrays, but I can not find it. It is easy to get the spacing from a drawing when the array faces true south, but when the array faces southeast or southwest is what we need to know. Please help. Thank you very much.
