Inovation of a photovoltaic power system with battery storage
Pallová, Ivana ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
This diploma thesis is focused on the Innovation of the existing power plant with battery storage. In the theoretical part, the individual parts of the photovoltaic power plant are introduced, the principle of operation of the photovoltaic cell and the individual types of these cells are desribed. The work also deals with the description of the existing photovoltaic power plant and their components. Subsequently, a battery systém and otherpossibilities of Innovation with the possibility of a subsidy and without it are designed. In the final part, the most advantageous solution is evaluated according to the performes simulations.

Solar systems utilization for family house energy demand
Šamanová, Jaroslava ; Toman, Filip (referee) ; Sitek, Tomáš (advisor)
Solar systems are more and more common part of residential houses. Main reason for this, is that solar elements are state-supported with subsidies, which is reducing payback time of these investments. At the same time, the prices for these systems are dropping. The state support is connected with effort to reduce dependancy on non-renewable energy sources, e.g. coal powerplants, which are polluting atmosphere. State administration i salso the reason for large scale solar powerplant constructions, which are, according to some opinions, misshaping the landscape and covering large areas of sometimes fertile land.

Concept of Charging Stations with off-grid Operation for Electric Bicycles
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This thesis deals with charging stations for electric bicycles powered by renewable energy. The aim of this work is to make a proposal for the hybrid charging stations for electric bicycles, which will work independently and, if necessary, will be backed up by a network. In this thesis is entered theoretical information on the issue of electric bicycles, the batteries, charging stations, the connectors of chargers, and photovoltaic systems. The practical part of this thesis is the basic design of the charging station and its design of the mathematical model of the individual parts in Simulink program, which are linked to the actual design of the charging station. In conclusion, this thesis deals with energy and economic analysis of the proposed system, therein included various methods of assessing investment recommendations of appropriate processing methods and overall assessment of the subject.

Design of a photovoltaic system and its economic evaluation
Hausner, Josef ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This Bachelor’s thesis deals with design of the photovoltaic system on a roof of a prefabricated house. In the theoretical part the current technology of photovoltaic cells and panels is analyzed. The next part clarifies current legislative conditions in the Czech Republic. A photovoltaic system is designed in the practical part. In the last part, the project is economically evaluated using a method of the net present value and the internal rate of return.

Solar charge controllers for off-grid systems
KRČKA, Pavel
This diploma thesis deals with photovoltaic rechargable regulators used in isolated, or off-grid photovoltaic systems. First, basic types of off-grid installations, including their functions and applications in practice are described. Then, possibilities of electric energy accumulation in photovoltaic systems are mentioned, considering actual, accesible technologies. Matters of electric energy accumulation in leaden accumulators are examined in detail. Main part of the diploma thesis is about electronic designs of photovoltaic, also called solar, rechargable regulators. These are the main connecting part between photovoltaic panels, accumulator, but also often connected charge, which is appliance. Individual electronic regulators concepts are described narrowly, then compared and evaluated in thesis´ conclusion.
