Solar cogeneration system based on a Stirling machine with improvements in the piston system as well as in the heat receptor and cooling systems. The invention includes a parabolic solar tracker for collecting the solar energy in the heat receptor of the Stirling motor, which converts this heat into mechanical energy by a thermodynamic process of expansion and compression of a gas confined in the inner portion of the machine. Finally, the obtained mechanical energy is converted into electric energy by means of an electric generator of double radial stator and annular magnetic rotor, which is coupled to the crankshaft of the Stirling motor within a hermetic carcass pressurised at the medium pressure of the working gas. The heat of the motor is removed in a cooler refrigerated by water or any other mixture. Said heat is used when requiring hot water, either at domestic or commercial level. |
