Leave the trailing section cut in two pieces so that the air/moisture/heat can flow through the front and back. Sealing the back section completely will pile up condensation inside.
Hello, nice information. I have one query. Can we glue the flexible solar panel to thermoplastic PVC sheet having 12-15 mm thickness? And can this sheet then glued to the roof (IBR or corrugated) of the house? (We want that way as there are chances of roof replacement, in that case we want the panels not to be damaged)
