The development of the model of PV system for electric water heating
Sochor, Tomáš ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This thesis deals with designing of a model of a photovoltaic system for domestic water heating in program PSCAD. In theoretical part, an analysis of photovoltaic systems regarding their connection to electrical grid is made. Then a description of chosen concepts of photovoltaic systems for domestic water heating is made. Furthemore, a photovoltaic cell is described with regard to its mathematical description and influence of different parameters on its volt-ampere characteristics. Also, a common topologies of DC-DC converters are described. Control is also related to these converters, that is why a fundamental MPPT algorithms are described. Practical part deals with designing of chosen concepts of photovoltaic systems for domestic water heating in program PSCAD. A basic simulations with regard to behavior of these systems are performed, especially a relationship with respect to irradiance and temperature. Simulations are then discussed in the conclusion.

Design of a photovoltaic power plant with battery storage for a family house in area Ústrašice
Wiesner, Lukáš ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
The master thesis covers the design of a photovoltaic solar power plant for a selected family house in Ústašice in Tábor’s region The theoretical part summarizes the photovoltaic phenomenon, production, and differences of various technologies of photovoltaic panels and different types of battery storages. The project also includes the legislative and subsidy conditions in the Czech Republic related to the PV topic. The practical part of the thesis starts with information about the layout of the family house with an analysis of household consumption data for the last five years. The analysis is followed by the selection of a suitable type of system for photovoltaic water heating. Using multi-criteria analysis, the most suitable solar controller and PV panels are then selected. The proposed system is updated with other necessary components. Finally, a simulation of the system is created in PV*SOL to determine the lighting conditions and to evaluate the economics side of the entire project.
