Financial return of home photovoltaic power plant
Jančík, Josef ; Malý, Milan (referee) ; Mauder, Tomáš (advisor)
This thesis if focused on return on ivestment evaluation of a photovoltaic system of residential house. The calculation is made for photovoltaic system with and without accumulation and in combination with other alternative source – heat pump. The costs of instalation and working of new systems are then compared between each other and with the cost of working of a current system without photvoltaic.

Proposal of measures in the low voltage network for the implementation of renewable sources and electromobility according to scenarios NAP SG
Vojtěch, Jan ; Kučera, Michal (referee) ; Ptáček, Michal (advisor)
The thesis analyzes legislative and strategic documents of the European Union and the Czech Republic which set targets in environment and energy area in 2030, alternatively in 2040. The individual chapter is dedicated to national action plans, where the most important is National Action Plan for Smart Grids setting specific requirements for future development of smart grids. The thesis contains analysis of distribution network in the municipality of Následovice and simplifying assumptions for the implementation of calculation. There are also introduced scenarios which have been used for the calculation of the distribution network with its results. Potential defects of the distribution network are commented with suggested solutions. The calculations were repeated to verify the solutions. Results are recapitulated in an individual chapter. Graphical outputs of the calculations can be found in the attachement.

Microphotovoltaic systems
Nováček, Richard ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
Master thesis deals with photovoltaic components and their principles. Evaluate the types of photovoltaic systems and their impact on the transmission system. The thesis deals with financial support to small and micro-photovoltaic systems, which can be used in terms of legislation of the Czech Republic. There are also described the changes in the amendment to the energy act and effect on the price of electricity in households. Compared with the domestic photovoltaic rest of the world and the view of the German energy concept. Part of the theoretical design of a hybrid photovoltaic plant, including the use of heat pump. Thesis deals with using hybrid photovoltaic plant and economic viability of the proposed system. The last part deals with the implementation of the proposed system and assesses the true value from those anticipated in the design.

Heating systems with the use of renewable sources
Hrdličková, Petra ; Blasinski, Petr (referee) ; Formánek, Marian (advisor)
The thesis is interested in renewable energy sources and their use for heating systems of a multifuncti-onal building. It is a community centre including housing units for the elderly and medical facilities. The topic of the first part of the thesis is renewable energy sources such as solar, wind, water, biomass and geothermal energy and the equipment that uses these heat sources. The devices mentioned include pellet boiler, biogas plant and heat pumps. The second part focuses on the design of the heating, hot water and heat source. The second part includes drawings, a technical report and annexes. The third part is experimental and deals with the technical data obtained, from a cascade, of one ground-to-water type heat pump in Čejkovice.

Heat pumps for heating and hot service water preparation
Valášek, Martin ; Hrnčířová, Michaela (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is aimed to describe heating and water warming in the detached houses by basic technical devices and there are suggested various types of heat pumps for a particular object. These heat pumps are compared technically and economically. In the beginning of the thesis there is a summary of the possible ways of the house heating and water warming systems, such as heating by electric power, by gas, by solid fuel or the centrally distributed heating. Then the thesis concentrates on heat pumps. There are described various types of heat pumps, also their advantages and disadvantages. There were chosen four main types of heat pumps – air/water, air/air, water/water and earth/water – and with each type there’s constructed a plan for a low-energy house heating. This house is located in Vyškov and there’s thermal loss of 6 kWh and water-warming of a capacity of 260 l per day. At last there were used economical calculations, which shown, that the water/water heat pump has the shortest return rate in comparison with a gas-using heating system – 5 years. Considering the lifespan of the heat pumps – 10-20 years – all the heat pumps are profitable except for the air/air heat pump. The investment in this heat pump doesn’t return.

Renewable energy sources in CR
Žaloudek, Martin ; Moskalík, Jiří (referee) ; Fiedler, Jan (advisor)
The thesis consists of the definition of biomass and its exploitation as a sustainable resource. It describes different types of biomass and their influence on the process of transformation to use for energy needs. It also introduces possibilities of electric energy and heat production out of this raw material, accompanied by an illustrating example of biomass as a suitable fuel. The end of the thesis evaluates the importance of biomass as an energy resource for the Czech Republic.

Creation of laboratory exercises for Renewable sources of energy
Bajgl, Tomáš ; Jandová, Kristýna (referee) ; Křivík, Petr (advisor)
This diploma thesis deals with the transformation of solar and wind energy into electrical energy by using a photovoltaic panel and a wind turbine. The work gives insight into the Czech Republic’s issue of energetics in the context of historical development, the current state, and the expected future development. The primary attention is given to the renewable sources - the solar energy and wind energy. Basic principles of creation and manipulation of solar and wind energy are described in this work. Two laboratory tasks are created for the Renewable Energy Sources' class as a part of the practical part.
