Solar Portable or Mounted

When I mounted my panels to the roof, I used the four aluminum brackets that came with each panel. Before installing them, I placed two sided tape between the bracket and the roof. I do this on many things that can use a little extra support, plus it adds some sealing capacity. Screw them down without over tightening as earlier stated. Finish off the edges and screws with Dicor and you have three attachment systems in place, two sided tape, screw(s) and Dicor. They won't come off. I also mounted mine in line with the A/C unit(s) to keep the wind from whipping under them.
