No, but I used the heaviest brackets I could find and used a total of 7, 3 on each side, and had to make a custom one for the front of each panel due to the curvature of the roof. I made a wooden frame of 1x2 lumber the size of the solar panels to lay out the placement the mounting brackets on the roof. Try to locate the brackets on the roof studs, I used butyl tape under each bracket and sealed the top of the bracket with dicor self leveling sealant. Mounted each panel with 14 #10 SS screws. Your panels being smaller may not need as much support.
Love my solar!

Hi. I saw one of your replies that mentioned you used a residential solar panel for your PV install. I have some slightly used 230W residential panels I'm hoping to use. Did you happen to capture any of your install on a thread here in the forum?
