TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Module: The module is characterized by the fact that each parabolic reflector (13) concentrates the SR, which is transmitted through the transparent surface (14), at an inlet (BI) of a mixing optical system (OS) as an incoming light flow (RTD). It is characterized by the fact that the OS is made in the shape of a truncated pyramid, whose side walls are shaped so as to reflect and mix the incoming light flow (RTD). It is characterized by the fact that the parabolic reflectors (13) are made from a sheet metal, which is stamped and mirror-polished, or from plastic supports obtained from mirror-polished and metalized moulds, or from printed and metalized glass. It is characterized by the fact that a reticular structure is provided within the module (11) comprising internal portions (19) of each elongated element (12) and flow tubes (20), made of conductive material, which are connected with low thermal resistance to the elongated elements (12), so as to facilitate a heat exchange with the air inside the module (11) and to transport the heat towards the base support (15), which is thermally connected to the internal portions (19) of each elongated element (12). It is characterized by the fact that each photovoltaic receiver (16) includes: a base plate (22), made with conductive tracks, with high thermal conductibility and high electrical insulation, the at least one photovoltaic cell (CS), at least one by-pass diode (23), which is parallel-connected to the least one photovoltaic cell (CS), at least two shaped elements (24, 25), made of conductive material, to which at least one wire (30) is connected for electrically connecting in series at least two photovoltaic receivers (16) and at least two respective photovoltaic cells (CS). It is characterized by the fact that the by-pass diode (23) is positioned below at least one (25) of the shaped elements (24, 25), in order to be protected from the incident solar radiation (RTD). It is characterized by the fact that the at least one SC is mounted and electrically and thermally connected to the base plate (22). It is characterized by the fact that at least one transparent rear surface (14) is placed at the base support (15) and the parabolic reflectors (13) are fixed on the transparent rear surface (14), within the module (11). It is characterized by the fact that the at least one wire (30) is without insulation and is welded at the ends (31) of the shaped elements (24, 25) of each photovoltaic receiver (16) and suspended at a fixed distance from the base plate (22). It is characterized by the fact that the module (11) is connected to a 3-phases DC/DC converter, in particular to a boost interleaved converter, which is controlled by a controller (M), which regulates the power drawn by the module (11), in order to maximize the power intensity and the maximum current of each module (11) which are available and usable by the electrical load connected downstream the converter, at any given time of operation. It is characterized by the fact that the output of the converter is electrically connected in parallel to the outputs of other converters of other modules (11). It is characterized by the fact that the output of the converter is electrically connected to the input of an inverter or DC/AC converter, which is connected to a public power supply (39). Preferred Generator: In the generator, the modules (11) are mechanically connected to a single support (32) and are electrically connected one with each other, so as to provide an output DC bus with its terminals (C1, C2) connected to the input of a DC/AC converter, which is able to inject into the public power supply (39) the electricity supplied by the generator. The generator is connected to at least one inverter (35) with circuit breaker and control system for engines of the solar follower (33). The generator (34) is integrated in a management system for electricity and/or home automation and the inverter (35) is connected, via radio, with a first counter (37) of the electricity supplied from the generator (34) and injected into a home power supply (41) and/or with a second counter (38) of the electricity which is consumed and/or with an intelligent switch (40). The control unit (44) controls the generator (34) and the photovoltaic system by communicating, via radio, with sensors and/or actuators for home automation, for security and for anti-intrusion, such as passive infrared detectors, perimeter sensors, smoke detectors with emergency light, gas detectors, flood detectors, remote controls, portable radio keyboards, outdoor sirens, intelligent sockets (42) which manage relative electric loads (43) and/or mobile terminals (45), such as touch screen terminals, with a telephone, alarm, command and control functions related to the photovoltaic system and/or to an electrical plant, a light system, a security system, a home automation system and/or to other automatic devices, such as open-gate devices, open doors devices, alarms, etc. The intelligent switch (40) measures the electrical power which is exchanged between the electric loads (43) and the public power supply (39) and controls the disconnection of the electrical loads (43) when the power drawn from the public power supply (39) exceeds a prefixed upper value, indicating the excess of the value, via radio, to the inverter (35) so that the inverter (35) injects into the public power supply (39) the missing power by drawing energy from a battery (36) or from the photovoltaic generator (34). The intelligent sockets (42) control the operation of the relative electric loads (43) according to the electricity which is available from the photovoltaic generator (34). The intelligent switch (40) detects a blackout of the public power supply (39) and disconnects the home power supply (41) from the public power supply (39) and controls, via radio, the inverter (35) in order to activate it as a main generator of electricity, the inverter (35) being able to activate at least some of the intelligent sockets (42) of the home power supply (41), so as to ensure the availability of electricity to the sockets (42).
