Analysis of a Photovoltaic Power Plant Operation
Šidla, Ondřej ; Borecká, Marcela (referee) ; Baumgartnerová, Alena (advisor)
Tato práce umožňuje náhled do problematiky fotovoltaických systémů a jejich využití pro výrobu elektrické energie, která hraje v dnešní době důležitou roli. První část je především zaměřena na charakteristiku vybraných fotovoltaických článků. Dále se práce zabývá legislativou v oblasti fotovoltaiky v České republice. Tato kapitola je pak dále rozšířena o kroky potřebné k realizaci fotovoltaické elektrárny. Závěrem je provedena technicko-ekonomická analýza konkrétní fotovoltaické elektrárny.

Photovoltaic cell for concentrator system
Straškraba, Vojtěch ; Solčanský, Marek (referee) ; Vaněk, Jiří (advisor)
The subject of this master’s thesis is to introduce concentrator photovoltaic systems. Main subject of presented work are photovoltaic cells and their features and characteristics. The work deals with physical fundamentals of solar cells, type of cells and their specifics and discusses possible treatment for achieving better characteristics of concentrator systems. In the practical part is realized measurement and analysis of electrical characteristics of 9 different monocrystalline silicon cells. From those is the most efficient cell chosen for further use as reference cell.

Characteristics features of luminescence radiation solar cells
Malý, Martin ; Šimonová, Lucie (referee) ; Stojan, Radek (advisor)
This thesis deals with characteristic features of luminiscence radiation solar cells during electroluminiscence. Electroluminescence is the process in which a substance begins to radiate electromagnetic radiation (luminiscence radiation) due to passing electrical current. Various defects in the structure of the photovoltaic cell can cause polarization of that radiation. The aim of this thesis is to measure some polycrystalline solar cells by electroluminescence. Selected solar cell is measured by electroluminescence extended by polarizing filter and afterward collected data are processed in MATLAB.

Renewable energy sources in CR
Kozumplík, Ondřej ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech republic. It appears here the principal, use, potential and advantages and disadvantages of each type of renewable resources - water, wind and biomass. Then the use of solar energy for photovoltaic conversion to electrical energy is described in detail. At the end of this study is described one of the many recently build photovoltaic power stations in the South Moravia territory, the solar power station in Bzenec.

Model for energy control from solar panel
Hromek, Jiří ; Dvořáček, Martin (referee) ; Malounek, Petr (advisor)
This is specifies problems of electricity development from the sun. It informs about the principles and especially means of optimizing of extracting maximum. There is created a prototype in the Matlab/Simulink environment representing a source of radiation and a solar panel. A prototype output is an extracted voltage for a different angles of panel tilt compared to a light source and a different lighting intensity. A prototype is practically realized then. Then there is devised a procedure of prototype for a maximum voltage extracting from solar panels. A prototype is liable to connect to the programmable controller of B&R company.
