The Stirling Thermodynamic Cycle
Macháček, Jan ; Sokanský, Karel (referee) ; Kyncl, Jan (referee) ; Gregor, Jan (advisor)
My doctoral thesis deals with study and analyse of Stirling thermodynamical cycle. Cycle that is composed of two isochoras and two isotherms. I describe functional principle of Stirling engine and all its parts, constructional variations of pistons system and possible engine working modes. Next chapter contains analyse of engine constructional parameters. Measuring of torque and load characteristics, p - V schemes and output work for various engine inputs is part of this analyse. There is composed mathematical engine characterization by means of Schmidt theory in chapter five. Mathematical characterization is consequently applied to engine model. Theoretical analysis and practical measurement were base for concepts, realization and verification of constructional correction. One part of my thesis is attended to design of new lamella for regenerative exchanger. For optimal lamella constructional proportions were used computational algorithm and simulations. There is concept of cogeneration unit with Stirling engine and its benefits check in last chapter. General theoretical and practical analyse of workable Stirling engine is result of my thesis. Analyse in this extent was not nowhere publishing yet. Design of regenerative exchanger lamella is then practical input of my thesis.

Renewable energy souurce in Czech Republic
Sojka, Jiří ; Fortelný, Zdeněk (referee) ; Moskalík, Jiří (advisor)
This thesis is focusing on exploration of various renewable energy sources used in mass-energy in the Czech Republic. The first half of this thesis is focused to brief description of each renewable energy source. In the last part of this work was selected energy from biogas as the source of renewable energy to be more detailed described.

Solar heating tap water
Kracík, Petr ; Baláš, Marek (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with the heating of hot service water by means of solar energy through solar collectors. At the beginning the author describes the most frequent methods for heating of service water in Czech houses with the help of electrical energy, fossil fuel, gas and central heat supply, including the input expenses for buying equipment. The author describes a solar system and his basic elements and suggests two variants with supplement heating by means of electrical energy, which compares with electrical heating of service water. The overall thesis is conceived as a review of possibilities of heating hot service water in households with economical budget at the end of the work.

The Business-Related and Logistical Challenges of Entering the African Solar Market. Illustrated on the Example of Solarity.
Widauer, Philipp ; Vinš, Marek (advisor) ; Kolář, Petr (referee)
The thesis evaluates the principal business-related and logistical opportunities and risks on the African solar market which is often associated to offer the last unexploited economic opportunities on this planet. For this purpose, the author examines three major African trade unions and reviews the strengths and weaknesses of each regional coalition. It becomes obvious that each respective trade bloc contains one dominant player, in this case Nigeria, Kenya and South Africa. The practical section starts with an analysis of the appropriate entry market for the Czech solar wholesaler Solarity. Subsequently, the author identifies South Africa as the best fitting market primarily because of good infrastructure, high purchasing power and a similar business culture. The author recommends that Solarity should apply an exporting entry mode due to its size and inexperience on the African market. Secondary research, first-hand experience and close cooperation with Solarity support the author in his final conclusions.

Evaluation of a Photovoltaic Power Plant
Hrubjáková, Martina ; Krause, Josef (advisor) ; Scholleová, Hana (referee)
The aim of this master's thesis is the evaluation of a company, of which the purpose of its existence is the development and running of a photovoltaic power plant. The estimated value refers to December 31st, 2011 and is determined for the purpose of potential sale of the company. The thesis consists of theoretical part, which includes determination of basic terms and concept of the evaluation process, and the practical application of theoretical knowledge on the specific company. A brief presentation of the company is followed by the strategic analysis, which identifies the most important opportunities and threats for the company in the future. Together with a review of previous company's financial results it represents the initial point for the preparation of a financial plan. The final part of the thesis includes the evaluation of the company in two versions. The first one is based on the assumption of termination company's activity after a specific period. The second one is based on the going-concern principle. The statement about the value of the company is supplemented by the valuation of the investment project.

Současnost a budoucnost fotovoltaiky v České Republice z pohledu velké energetické společnost
Burianová, Eva ; Jaklová, Martina L. (advisor) ; Kubín, Petr (referee)
Goal of this thesis is to analyse sequence of events that led to current situation on the solar market in Czech Republic. Based on this analysis, current situation and scenarios for the near future from the point of view of large power utility company are described. For this aim, analysis of macro-environment is employed and focuses in detail on legislative and technological factors. Definition of possible scenarios starts with the description of current situation of saturated market. Solar power plants are then presented as reasonable equity investment from the point of view of large power utility company. Assumptions and entry data are described and the investment is evaluated using the net present value evaluation tool. For chosen entry parameters, sensitivity analysis is performed. This thesis then defines the situation when electricity produced from solar irradiation becomes competitive with other conventional sources.
