Our Compri solar zero ballast system gives you the option to mount a solar under construction on a flat roof without screwing thru the roof surface itself. By means of a unique stainless steel base plate and a bitumen surface treatment you are able to glue the construction on the bitumen roof. The zero-ballast system can also be supplied with a coverage of epdm or pvc. Due to pre-drilled holes in the stainless-steel base plate you are also able to screw the system on the roof if the use of bitumen is not possible.
