Module for mixed photovoltaic and thermal power generation from solar radiation, and plant provided with such modules

A module for power generation from solar radiation comprising a casing (2, 2.1, 2.2) including:

• a first wall (3) exposed to solar radiation and provided with photovoltaic cells,
• at least a second wall (7), spaced apart from the inner surface of the first wall (3),
• an intake (9) for fresh air, to provide air circulation inside the casing,
• and an outlet for the air which has been heated,
• the power being generated as electricity by the photovoltaic cells and as heat from the heated air, wherein:
• the first wall (3) is partially made up of a photovoltaic panel (4) with the other part made up of a transparent plate (5),
• the space between the first and second walls (3) and (7) is free,
• the inner face (7a) of the second wall is dark,
• the air circulates between the walls (3) and (7), thereby cooling the inner faces of the photovoltaic cells, and is heated by the part of the radiation that has passed through the first wall including the transparent plate (5), and by contact with the dark face (7a).
