I wouldn't worry about 600 AH battery bank with 500-600W solar. With your stated use of 50-100 AH max, your charging cycle will be shallow, in the morning the battery will be 75-85% (even with some non-linear high draw of inverter). Your solar will charge it fully if there is 4-5 hours of unobstructed sun in summer.
3-dimensional CAD of panels layout that would show shading at different hours, can be complicated. Cardboard is more "visual", you see the shade and what happens when you raise it 3", and how much space is left for walking around.
