The modules are for commercial flat roof design on buildings that where extra weight is a problem. May be used differently later.
Photovoltaics are still a troublesome thing to have installed on roofs. Without being able to disable them, firefighters won’t try to chop through them. Maybe a photovoltaic that requires some kind of priming power to keep in power generation mode would prove more attractive. Cur the priming power and now they can be chopped through safely.
Cur => CUT.
