Abstract: A modular panel to make a roof or a wall of a building comprises an external shell and an internal shell, made of moldable plastic material, coupled with each other to define at least a compartment. The panel integrates in itself means for the capturing and irradiation of energy, and relative energy accumulation means, the capturing and irradiation means being associated, at least partly, with the external shell.
