Not everything is perfectly true, square, and plumb. That's why I wanted to use the panels instead of templates.
I also am spacing the panels with 16p nails to allow for some expansion. They're mounted on rubber washers to insulate the materials from each other.
I want them as close as possible to each other. Then I'll cover the gaps with butyl aluminum tape to make the roof waterproof.
I have another set of rails that I need to mount, that'll account for 12 panels, then i'll need to go get more rails for the 3rd and 4th set. Then after that, I'll need to get more framing to build more structure.
But 24 panels will be enough to get me started with my 4x3kw growatt inverters.
