Panasonic's "Functional Roof System" without Piercing the Roof

Panasonic released on 17th that it had developed a new type of solar panels for residence rooftop.

The system doesn't need to pierce the roof, which means it is free from rain leaking. The panel can be installed and detached whenever the owner wants.

Also, it takes a heat-exhaustion structure, which has wind passageways behind panels.
