I am looking for ideas & products to keep the area under my solar panels dry. My panels are attached to strut channels and the struts are connected to the wood framing (see photos). I don’t want to use caulking and I am thinking to overlap the panel edges, by an inch (top-to-bottom, in the rain flow direction), have a main gutter at the bottom to capture all the rain, and use gutters under each adjacent section (top-to-bottom to capture rain, and divert to the main gutter). Thanks in advance for any ideas / product recommendation / photos / videos / etc.
