Photovoltaic, as an alternative source of electricity
Floková, Kateřina ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is to provide a description and an explanation of the process of obtaining elektrical energy from solar radiation. There is preliminary mentioned an importance of producing electrical energy from renewable sources and development of photovoltaic systems. The body of the thesis is divided into seven chapters. At first, there is described the principle of transformation solar radiation into electrical energy. Then, the description of types of barrier-layer photocells follows. The types are divided according to their structure and material, which are they produced from. The third chapture is focused on production and construction of photovoltaic modules. Ways, how can be production of electricity increased, are mentioned in the fourth chapture. Advantages and disadvantages of solar concentrators are given there. In the fifth chapture there are described two basic kinds of connection of photovoltaic system. Different ways of taking-off produced electricity are related with those kinds of connection. The last chapture is the fundamental chapture of the thesis. There is given a project of concrete photovoltaic system. For this system is calculated economic return of investment included supposed increase of prices of electricity. In conlusion the author noticed events that would be given and emphasized the outcome of concerete project of photovoltaic system.

Photovoltaic systems in the cities
Dobiáš, Pavel ; Procházka, Zdeněk (referee) ; Mastný, Petr (advisor)
This Bachelor thesis' main goal is to introduce a potential reader with the photovoltaic system questions and its utilization in many applications. In the leading chapter the thesis deals with the potential of the energy which is radiated from the Sun towards the Earth. It tries to analyze the common problems of using this energy. The next part deals with simple semiconductor operating principles and explain the principles of photovoltaic cell functions. The upcoming part deals with the construction and basic types of photovoltaic cells and show the possible ways in their development. In the next part there are analyzed many types of photovoltaic systems and their application in praxis. In the next part the reader is introduced with the meaning of photovoltaic as a renewable source and with its support in the European Union and Czech Republic. The last part deals with design of four devices which uses photovoltaic system as a power source and which can be used in the city agglomeration environment.

The grid-off Wind Power, Principle, Effectiveness, Return
Havránek, Miroslav ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
This Master´s thesis deals with problematics of wind powered generators and their use in off-grid systems. In its first chapters aspects of wind as a power source are analyzed. Further on the thesis focuses on individual components of the off-grid systems. Also designing procedures of these systems are presented in the paper. The key parts of the thesis are 3 off-grid wind power system designs, which can be used to power a family house, and their energetical and economical evaluation.
