There is a lot of water getting into my panels when it rains so I am tearing them all back off to add some sealing tape. I will use foil tape folded over the top edge of each panel and a breathable tape on the bottom edge. When I put them back on I put a small square of bituthene on both sides of the panel where the mounting screws were. All the seams will be covered with 2.5" strips of bituthene and on top of that I will put 3" foil tape.
