I'm currently building the roof of my house, on which I intend to have solar panels. I see there are solar panel mounts readily accessible for all kinds of roofs except reed roofs. My understanding is that any rails need to be attached to the rafters before thatching, however, I see there are examples like the first image where the panels are mounted directly on the roof. I would prefer not to go that route, as I would like the panels to be modular, however, I can't find rails nor directions on how to securely mount on a thatched roof so that there would also be airflow below the panels for increased efficiency.
If there are no rafters over 30cm tall, is there a way to build your own wooden rails on which one could fasten the panels, or something similar?
In the first photo, it looks as if the solar array is treated as if it is one large "penetration" in the roof, like the roof windows. The thatch around it, but not underneath. Maybe it is a more modern, rubber membrane roof beneath the panels, with mounting rails, then panels on top?
How are other roof penetrations dealt with in thatched roofs? Such things as drain vent pipes? Do they avoid the roof and vent through a wall? If you had a series of pipes, you could mount rails to... though, I think you might have moisture problems with thatch below the solar panels...therefore the method in first photo.
Thanks for the replies. Pearl, I believe the roof should hold, I'm adding an extra roundwood rafter, plus the roof is at a 55º angle, so my understanding that the rafters will have more vertical support than normal. As you can see in the photo, it's woodland all around, so panels on the roof seem most ideal to me to capture as much sunlight as possible.
Kenneth, my goal is to forego any unnatural resources like plastic membranes where possible, and I intend to have the panels stick out above the reeds so that moisture can't build up. I imagine I simply need to flash the mounts that stick up.
