Engineering solution of photovoltaic power station
Gajdošík, Ivo ; Sobotka, Jiří (referee) ; Míča, Ivan (advisor)
This thesis deals with the usage of solar photovoltaic panel production of electic energy. First part focuses on solar radiation alighting the Earth, respectively the area of Czech republic. Next part covers a development of photovoltaic from the very beggining til nowadays, it describes its spread in the world and the area of Czech republic. Then a reader us introduced to physical principles that work inside solar cells a one single chapter desribes individual parts of photovoltaic power station. Next chapter is dedicated to a model study of photovoltaic power station devided in two alternates- with stacionary placement of panel and placement on trackers, where after a market research, there is a whole technical solution designed and economical and delivery balance is calculated. At the last part there are described main directions of development in the field of usage of solar energy for electric current production.

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.

Model of a lighthouse with photovoltaic power
Dvořák, Adam ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
The aim of this thesis is to aquire and present the knowledge about the principles of the photovoltaic effect and panels and then discuss a theoretical analysis about these two topics. Task of the second part in this project is to design a theoretical model of a lighthouse, using pieces of information about photovoltaics which were acquired from the first part. And in the end physicaly realize designed model. In order to reach the best possible level of effectivity over the whole year, correct planning of the orientation and angle of placement while taking into consideration the movement of the sun is required before positioning the photovoltac panels.

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.
