Concentrator photovoltaic systems
Straškraba, Vojtěch ; Solčanský, Marek (referee) ; Vaněk, Jiří (advisor)
The subject of this bachelor´s thesis is to introduce concentrator photovoltaic systems, history of their foundation, evolution and application, principles of function and description of technology including its construction, optics, special photovoltaic cells and their cooling. The practical part of thesis describes the experimental concentrator photovoltaic system build in cooperation with Solartec s.r.o. company. The system is used to test hypotheses and study the behavior during its operation. The aim is to measure concentration ratio, temperature and electrical characteristics and to compare advantages of active and passive cooling of photovoltaic cells.

Energy-efficient building of Bosonohy Primary School
Vlha, Daniel ; Blasinski, Petr (referee) ; Počinková, Marcela (advisor)
The aim of this master thesis is to design a nearly-zero energy primary school in Brno-Bosonohy. The thesis consists of 3 parts. The first part contains architectural and structural design. The second part deals with the design of the concept of building services. The building is designed without a basement and has three above-ground floors. The structural system includes longitudinal masonry wall and prestressed prefabricated floor panels. In the lower part of the building there is a lunchroom, above which there is an operating roof. In the higher part of the building, there are 4 form classes for a total of 120 children, a language lab, a laboratory and a atelier. The building is heated by a ground-water heat pump with deep bore holes, which are also used for hot water heating. The ventilation has a heat recovery system with high efficiency. Photovoltaic panels are installed on the roof. The third part analyses data from a local survey at the primary school. The analysis is focused on the temperature in the room in the summer season, and then the management of building services is optimized to energy consumption. The conclusions from the third part were applied to the design of the school, which is the subject of the first and second parts of this master thesis.

Systém aktivního chlazení fotovoltaických panelů pro zvýšení jejich účinnosti
LANDKAMER, Ladislav
The work was divided into two main parts. The first one dealt with the analysis of the problem of influencing the performance of photovoltaic panels by active cooling. Based on the results of the analysis, an optimal system for active cooling was designed with respect to the performance enhancement but also to the damage elimination possibilities. The parameters for the implementation of the system were specified depending on the analysis performed. This analysis provided answers to the choice of the appropriate technology and to the technical design of the whole system. The second part of the work presented the actual technical solution. In the form of its design, construction, programming and testing of the resulting system.
