This paper presents the operational factors optimisation of the thermosun plant have placed within Electrical Engineering Faculty from ”Valahia” University of Târgoviºte. The thermosun plant is an automatic plant by means of a German equipment (its name is Sun-Go); this equipment is necessary for the thermosun applications. The measurements were performed during one week and were computed by a computer, which is necessary for the data hold, and the data processing have calculated in C++. By means of these diagrams, it was obtained the optimisation of the operational factors. Regarding the continuous increase of the equivalent fuels price, the arguments for rigging of a building with a thermosun plant are evidently:• This equipment permits the simplest and most efficient exploitation of the sun power, the saving of the beneficiary costs begining in the same time with bringing into service of the equipment;• Generally, the sun power utilisation assures protection to the increase of the power price;• The sun power is ecological and is necessary for the preservation of the power conventional resources and to the firm decrease of the emissions of the pollutant substances.
