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.
