Aluminium Pergola rafter clip-on spacer for PV

Designed this in PTEG - bracket to clip onto top of the Pergola roof so that I could raise the back of the PV solar I have installed (to help angle the PV for self-cleaning as the dirt has been collecting on them when they've been flat all winter).

See image for size of clips - theyre designed to clip into the grooves each side of the pergola rafters, and then zip tied PV etc.
