How to deal with the seams of photovoltaic panels
You can mount PV directly to the roof panels themselves - using the “direct-attach” method. Whether you are dealing with standing seam or ribbed, face-fastened panels, these metal roofs have one thing in common: They all have built-in rails.

If you have a solar panel system installed using standing seam clamps, it’s a good idea to get them checked periodically for tightness. It is also vital that the roof covering is fixed well before the solar panels, to support them as the security of the panels depends on what they fix on too.
Standing Seam is great for mounting of the PV solar panels — no need to drill any holes in the roof, as PV panels are mounted onto the seams of the metal roof with the help of S-5 brackets. With a conventional roof, such as asphalt shingles, you would need to drill holes into the roof in order to mount the panels.
Below is a step-by-step procedure of how to seal between solar panels using a silicone sealant: Clean the surface to get rid of tape or any other material before starting the sealing process. Add the silicone sealant at the point where the glass meets with the frame or whichever edge protection is present.
The following article covers various metal roof types and their associated racking methods, reviews industry-leading metal roof racking equipment, and offers best practices in installing PV systems on metal roofs.
