Spacing between panels in a flat roof
I have been collecting quotations to install panels in my flat roof.
Multiple companies mentioned that 8 panels is the maximum (as 1st image), while a couple mentioned that 11 is possible (as the 2nd), and even one mentioned 14 is possible.
Can you just stack all the panels next to each other (as the 3rd photo)?
What do you take into consideration when decide the number of panels in a space?
