Method and apparatus for generating electrical energy
The invention relates to a method and a device for generating electrical energy, according to the preamble of claims 1 and 6. In order to achieve this that the efficiency of photovoltaic solar energy systems and the efficiency with respect to the generated electric energy significantly increased and yet the heat problem is solved, is according to the invention proposed that is provided by a medium in the flow of cooled area on the irradiation side facing away side a, the waste heat corresponds to an evaporator of a low temperature ORC system in which the results during cooling waste heat is nachverstromt in a turbine-generator unit.
The main innovation of the study is the use of a novel energo-environmental approach for investigation of biogas production, and analysis of the amount of methane and biogas produced in terms of en...
