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.

Photovoltaic, as an alternative source of electricity
Floková, Kateřina ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is to provide a description and an explanation of the process of obtaining elektrical energy from solar radiation. There is preliminary mentioned an importance of producing electrical energy from renewable sources and development of photovoltaic systems. The body of the thesis is divided into seven chapters. At first, there is described the principle of transformation solar radiation into electrical energy. Then, the description of types of barrier-layer photocells follows. The types are divided according to their structure and material, which are they produced from. The third chapture is focused on production and construction of photovoltaic modules. Ways, how can be production of electricity increased, are mentioned in the fourth chapture. Advantages and disadvantages of solar concentrators are given there. In the fifth chapture there are described two basic kinds of connection of photovoltaic system. Different ways of taking-off produced electricity are related with those kinds of connection. The last chapture is the fundamental chapture of the thesis. There is given a project of concrete photovoltaic system. For this system is calculated economic return of investment included supposed increase of prices of electricity. In conlusion the author noticed events that would be given and emphasized the outcome of concerete project of photovoltaic system.

Project of the photovoltaic system
Ševčíková, Kateřina ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
The diploma thesis deals with elaboration of project solar thermal and photovoltaic solar systems for all-season service. The theoretical part focuses on the general description of the solar thermal and photovoltaic systems, legislation of renewable sources in the Czech Republic and the status of photovoltaics in the Czech Republic. The experimental part deals with the design of measures for energy saving by using solar energy systems. These measures are proposed for construction of houses in Podolí u Brna, especially on extra-family house. The aim of the work is to make a proportioning, choosing the right parts and calculating the economic and ecologic balance. Finally, thesis gives recommendations for further action in saving energy in houses in Podolí u Brna.

Energy efficient terraced house
Král, Jakub ; Bečkovská, Tereza (referee) ; Bečkovský, David (advisor)
The aim of my diploma thesis is a design of a new energy efficient terraced house in the gap site. Building has two dwelling unit of category 4+kitchenette and 6+ kitchenette. Building has a cellar, two floors and an attic. The cellar structures and horizontal structures are made of reinforced concrete. Sand-lime bricks are used for masonry. The building is covered with gabled roof with timber roof truss. In this building there are used rainwater and renewable energy in a form of electrical energy made by photovoltaic panels.

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.

Analysis of floating photovoltaic usage in the Czech Republic
Al Halabi, Enas ; Vrána, Michal (referee) ; Paar, Martin (advisor)
Tato práce se zabývá technologií plovoucí fotovoltaiky, její strukturou, komponenty, vhodnými vodními plochami, výhodami a výzvami. Dále poskytuje přehled na její historie plovoucích elektráren a jejich nasazení na světě. Je popsáno základní hodnocení umístění pro instalaci FPV. Jako hodnocený vodní plocha byla vybrána vodní nádrž Nové Mlýny, v této lokalitě byl navržen a popsán plovoucí FV systém. V této studii je zmíněna srovnávací analýza s cílem porovnat konstrukci, náklady, provozní prostředí a výrobu elektrické energie plovoucího a pozemního fotovoltaického systému.

Energy retrofitting of a family home to the nearly zero energy building
Uhlíř, David ; Fišer, Jan (referee) ; Charvát, Pavel (advisor)
The diploma thesis is devoted to reducing the energy intensity of a two-storey family house from the 1960s, to a building with almost zero energy consumption. First, the family house is analyzed in terms of the condition before reconstruction. The result of this analysis is a certificate of energy performance of the building in its original condition. Within the individual chapters, I subsequently propose specific energy saving measures. At the end of each chapter, these measures are economically evaluated using the New Green Savings Grant Program. The first measure is dedicated to improving the thermal technical properties of the building envelope. This is ensured by the complex insulation of the family house and the replacement of the original windows and doors. The second measure is devoted to the design of a suitable method of forced ventilation with heat recovery. As part of the third measure, I assess and select a suitable heat source that will replace the original heat source of the family house. As a final measure, I propose the use of a renewable energy source in the form of a photovoltaic system, which is based on energy simulation in the program DEKSOFT FVE. At the end of my work, I am developing a building energy performance certificate, which assesses the fulfillment of the condition of a building with almost zero energy consumption.

Kindergarten Krabík
Jakoš, Milan ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
The aim of this master´s thesis is the elaboration of project documentation for kindergarten with almost zero energy consumption. The project consists of three main parts. The first part is devoted to the civil engineering design of the building. The building is designed regarding to architectural expression, quality of made and type of use. The kindergarten is designed with capacity of 48 children split into two departments. The second part is devoted to the design of HVAC systems. The building uses mechanical ventilation with heat recovery, heating is provided by two gas boilers and the need of electricity is provided by a photovoltaic system. Captured rainwater is used effectively. The third part values the building regarding the method of multi–criteria analysis. For this evaluation uses national method SBToolCZ.

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.
