Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.

Optimization proposal of size of PV systems
Vrzal, Martin ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The master thesis deals with proposal of size optimization of PV systems. According to results of optimization, alternative solutions of photovoltaic system were proposed for family house. From the perspective of costs efficiency were compared investment costs and savings of implementation of electricity supply directly to private consumption. Particularly for each of the proposed solution, profitability assessment of comparing purchasing costs and returns on investment was performed. Theoretical part of the master thesis consists of introduction into solar radiation principles, structure and functionality of photovoltaic systems, electronics inverters and accumulation of electric energy. The practical part is focused on measuring of electricity consumption in particular family house, calculation of sunlight intensity hitting tested house, making various solutions of photovoltaic power plants placed on the family house in order to evaluate returns on investments. In conclusion are summarized all results of investigated solutions according to economics aspects.

Energy system for energy independent object
Kaňovský, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This bachelor‘s thesis deals with a design of energetic system for energetic independent family house. There are default parameters for the house defined, and an impact of house's placement in nature on thermal energy loss and on thermal energy gain due to solar radiation is described at first. There are daily diagrams of thermal energy consumption for common and heating periods derived in this thesis. An energetic system producing electric energy using photovoltaic solar panels which are placed on the house's roof is designed based on the diagrams. The thesis also introduces basic types of island energetic systems. The objective of this thesis is also a design of energetic system for heating-up (TUV) using a thermal pump, fireplace and solar collectors.

Design of domestic energy supply system using renewable energy sources
Gaborčík, Michal ; Pavelka, Tomáš (referee) ; Matoušek, Antonín (advisor)
This bachelor thesis deals with possibilities of utilization of renewable energy sources for domestic power supply. In theoretical part is created research about available technologies using solar collectors, photovoltaic systems and heat pumps. In practical part there are calculated expected values of energy needed for heating of family house, domestic hot water heating and electrical consumption of appliances. These values are bases for system design using air to water heat pump for heating and domestic hot water heating. As far as photovoltaic system is concerned there is comparative design of systems using polycrystalline and thin-layer technology. At the end both designed systems are evaluated from technical and economical points of view.
