Operating diagnostics of PVP
Prášil, Kryštof ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the issue of photovoltaic power plants, especially their operational diagnostics and how to perform this diagnostics. The introduction of the work explains the principle of function of PV cells and describes the procedure for manufacturing these cells. Furthermore, there are mentioned methods of manufacturing individual components for assembling a PV panel. The next part lists the individual components of the PV power plant and describes their function in the entire system. At the same time, the connection methods of the PV plant are described. In the third part, we look at possible defects that affect the performance of PV systems and reduce their economic profitability. We will explain the defects of both the entire PV power plant and the individual panels and components. The following chapter is focused on explanation of individual variables related to PV power plants and what these variables are about. The fifth chapter deals with the content of the standard ČSN EN 62446. The last chapter concerns the diagnostics of the PV system itself, practical tests and evaluation of the results of these tests.

Energy management of residential building with a photovoltaic system
Prášil, Kryštof ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
This thesis deals with the evaluation of the electricity consumption of a family house with a photovoltaic power plant and electric heating. A control system was designed for this object, ensuring the optimization of consumption. The work summarizes the currently available options for power consumption management in buildings with photovoltaic plants. Subsequently, the thesis contains a description of the chosen management method. In the next part, the final algorithm of the control system is put together, which was preceded by operational testing and optimization. Finally, the thesis presents an evaluation of the energy and economic efficiency of the system.
