Systme for solar system control
Cseri, Peter ; Šembera, Jaroslav (referee) ; Bradáč, Zdeněk (advisor)
In the first part of my thesis, I was studying materials about using solar energy. Then I write search about all components that are necessary to be used in solar systems. After that I designed the structure of solar system used for heating the hot water for a family house about 4 persons. For this system I designed a regulator and one layer circuit board using Eagle layout editor 4.12r2, which I assembled and tested. This followed creating and debugging program for microprocessor that controls the whole device. This functional regulator for solar collectors connected in a box together with the necessary electronic components is my final product of this project.

Upgrade of testing workplace for solar cells
Řezníček, Martin ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The master‘s thesis is focused on the modification of measurement workplace for solar cells. In the first part of the thesis are introduced general problems of the solar energy and possible use in the international power supply, the details about the photovoltaic effect, processing of solar cells and their subsequent parameters. More further in the text the autor is concerned with causes of solar cells defects formation and representation of the most important defects. For defects detection are known the detection methods of solar cells, which are generally described in the text. The second part of the thesis includes detailed description of the LBIC method and workplace both the VUT Brno, and in Solartec, Ltd. The most important point of this part is project and description of innovated workplace from hardware and software realization. There is out of print the function and the description of the user interface and subsequently there are mentioned results gained from original and innovated workplace. In the conclusion are summarized whole activities of the master’s thesis, described and evaluated achieved results and outlined the direction, where would the other development of the LBIC workplace on VUT Brno be proceeding.

Analysis of the economic efficiency of a solar system
Mikl, Antonín ; Pithart, Jan (referee) ; Macháček, Jan (advisor)
The Master’s thesis deals with the processing of solar thermal systems for heating hot water, outdoor swimming pool and heating selected house. Introduces us how we can use the sun for the production of thermal energy through solar collectors. Furthermore, the basic components of the solar system and the types of collectors used. After this summary on the present state be the calculation of the system and fixing the price of the investment. The economic part of the evaluate if this system to invest, eventually appoint a return on investment.

Thermo-electric solar generator
Kočvárek, Ondřej ; Jakubová, Ivana (referee) ; Gregor, Jan (advisor)
The introduction of this work is devoted to the description of physical principals and condtruction of modern semiconductor thermoelectric transformers. This work describes thein basic characters and the most commonly used materials for thein production. Further, it mentions the basic principals and physical effects that describe the thermoelectric conversion of energy and the nondestructive method for establishing the basic material characteristics of thermoelectric transformers. The substantiv part of this work is the measuring of the material’s characteristics of the accessible thermoelectric elements through the medium of experimental measuring network. The optimal construction of thermoelectric solar generators used for individual thermoelectric elements are designed based on the taken measurements and the evaluation of material’s characteristics of the observed thermoelectric elements.

Operational efficiency of photovoltaic generators
Koval, Filip ; Václav, Březina (referee) ; Gregor, Jan (advisor)
Objective of master’s thesis theoretical part is especially to illustrate influence of operation conditions, such as solar radiation, temperature or pollution of photovoltaic generator active area, on load and power characteristics of photovoltaic generator, or more precisely on photovoltaic conversion efficiency. Possible variants of increasing effectivity of using photovoltaic generator are explored, such as solar radiation concentration, photovoltaic generator active area cooling or aplication of optimalization circuit. Pivotal part of master‘s thesis is focused on experimental device practical realisation, concretely type MSQ36-10 photovoltaic generator with oriented concentrators of solar radiation. Practical realisation includes design of master‘s thesis experimental part construction with subsequent design of photovoltaic generator motion cycle necessary for adequate simulation of configuration variants solved using single testing photovoltaic generator. Description of own experimental device construction with list of measuring places used in task takes up. It is used automatic monitoring system working as independent measurement task for required values measuring and consecutive data collecting. It is done in two phases. First phase is measurement of all required values, in second phase measurement with attached optimalization circuit is made. Optimalization circuit sets best working point of photovoltaic generator according to actual working conditions. Master‘s thesis intention is experimental verification of solar radiation concentrators application convenience, orientation of photovoltaic generator or its mutual combination, namely using type MSQ36-10 photovoltaic generator. Objective is evaluation of reached energetic gain for all experimental device layouts in variable operating conditions.

Science & Technology Park in Zlín
Kožíšek, Vladimír ; Svoboda, Jiří (referee) ; Zemánková, Helena (advisor)
The subject of this thesis is the project of scientific and technological park in the Tomas Bata University in Zlín. This park is divided into three workplaces: the educational and training center, a workplace for applied research, and business center. This project is situated at the location of a former factory area of Baťa Company; specifically in its eastern part. This dissertation is focused on the analysis of the given location, evaluates it in terms of its potential, and finally sets out the main priorities that should be applied in the draft. The accompanying report then describes and specifies the project, as drawn graphically, in the form of situational patterns, plans, sections, perspectives, and visualizations. Specifically, the project deals with the reconstruction of the former manufacture building No. 24, proposes a construction of a new building no. 25, and provides a solution for space in between of these two buildings. The project primarily seeks to make the entire site more attractive, and bring it to the function which would implement the functions in the assignment of the technology park. The function of the technology park is divided with regard to the investors requirements. From the urban point of view, the project seeks to approach the problem stemming out of the essence of the place. The use of objects remaining on the site preserved, is designed not to disturb the architectural expression and static essence. Architectural expression of new objects is selected not to oppose the overall architectural expression of the site. The project also includes and evaluates the usage of solar energy.
