Hey all,

I’ve got a set of three 60-cell panels and microinverters that I want to mount on an asphalt shingle roof. I’m planning to expand the array to 16 panels in time.

Does anyone have recommendations for low-cost mounting systems and online retailers that sell them? I like the idea of rails, but from what I’ve seen shipping costs are prohibitive and I’m trying to do this on a budget, so rail-less options are appealing also.

    Go to your local electrical supply shop and get Gantry or unistrut (name changes on local). Cut it to size and buy the clips and adapters to put it all together.

      I see the Unistrut SLR100 solar panel clamps and they appear to be UL-listed, so that does seem like a good option . I just need to find galvanized or aluminum strut locally.

      Do you have any recommendations for hardware to mount the strut to the roof?
