Hello. Did you use the automatic altitude feature? Right-click on the PV fields you want to adjust at the level of the ground and select 'Automatic altitude'. Does it fit on your ground?

yes but i still recieve the error of conpenetrating so i have to lower just a little bit the ground . is there a way to also reduce the size of the ground after i have finished to place the layout? and i have another question but of another kind.. if i have a 27 module string, but my pv layout is made of 9 modules arrays , how i can set the string in the shading scenes to make it considere 3 arrays as one string? the minimum x , y values i can set are 1 so i not know if it is possible to do to
