Degradation of Photovoltaic Modules
Poledník, Tomáš ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The bachelor diploma thesis is focused on the constructional technology of the solar modules as well as on the problems of the induced degradation under the influence of the potential. It specifies the key issues and possible elements that influence the effect of environment with regard to possible causes of the origin of degeneration. The thesis includes the description of measuring of the polycrystalline and monocrystalline technologies that are resistant to the leading potential. Furthemore, the measuring was carried out on the chosen testing pieces that had been affected by the degradation of the output

Design for a photovoltaic plant on the roof of a house
Kattauer, Jakub ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This bachelor thesis is focused on the issues of the fotovoltaic-electricity which is situated on the rooftop of the family house. The first part of this thesis deals with a solar radiation in the region of the Czech republic, photovoltaic conversion and electric attributes of solar cells. In the following part is analysed current status of an available technology of a sollar cells. The next topic which you can deal with is a process of the manufacturing of solar cells, basic selection and partition of inverters, construction and with the manufacture of the several kinds of connection. The next chapter is about to explain how you can gain an aid of the state from the bottom to the nowadays. The last part of this thesis is dedicated to a specific proposal of the fotovoltaic factory on the rooftop, calculation of an investments that are need to be paid and enumeration of a possible financial return.

Study of influence degradation to fotovoltaic cells properties
Tulková, Tereza ; Sládek, Petr (referee) ; Zmeškal, Oldřich (advisor)
The thesis examines degradation of photovoltaic cells and modules. Degradation assessment was based on the data gathered from the photovoltaic system installed at the Pedagogical Faculty of Masaryk University in Brno, Poříčí 31. The research focuses on influence of external factors on the amount of power supplied to the grid by the system. Theoretical part of the thesis summarizes state-of-the-art knowledge about photovoltaic conversion and devices taking the advantage of the principle. The first part of the thesis describes production and application of photovoltaic cells and their impact on the environment. Second part of the thesis deals with the principle of photovoltaic conversion. Next part lists materials used for the production of photovoltaic cells and the process of encapsulation. The fourth part summarizes knowledge about degradation of photovoltaic panels. Experimental part of the thesis statistically analysis the data gathered from the above mentioned power plant. Influence of degradation factors (surface temperature of PV panel, air temperature, wind velocity and radiation intensity) on effectiveness of energy conversion was examined in particular. The published results can be applied on analysis of new projects and/or used for modification of production technological processes.
