Measuring station for the system of the remote energy supply
Dočekal, David ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
This thesis is focused on the creation of measuring workplace for remote power supply system. This is the measuring of the workplace, engaged in the processing of measured data, the production of electrical energy made by a photovoltaic panel and wind turbines. In the theoretical part, the reader is familiar with the issue of renewable energy sources. The first chapter is about the energy of the wind. Here is described the emergence of the wind, the basic division of wind power, through the production of electrical energy to the measurement itself. The second chapter deals with the solar energy. This chapter describes the emergence of the solar energy, photoelectric effect, description of characteristic features and related evaluation of the photovoltaic panel. The reader learns the basic distribution photovoltaic panels here and their manufacturing. The third chapter is devoted to measurement methods and specifying the basic conditions for the evaluation of the operation of wind turbines and photovoltaic panel. In the fourth chapter describes the basic data on individual facilities, which have been selected for this thesis and the involvement of the measuring site. There is also included wind power JPT-100 photovoltaic panels A-130 anemometer TX20ETH, pyranometer SG420 and temperature sensor PT100. Measuring software is described in the fifth chapter. In the last chapter, contains the experimental measurements in the selected time interval and the actual evaluation.

Solar irrigation
Straňák, Rastislav ; Jaššo, Kamil (referee) ; Jandová, Kristýna (advisor)
This bachelor thesis deals with the issue of solar irrigation system together with the design and manufacture of the owner´s solution. The beginning of the thesis deals with the analysis of commercial equipment, determining its possible innovations. It continues with the analysis and selection of individual components for author´s solution. Newly designed device has a microcontroller that evaluates data from the relevant components, thus controlling the system processes. Thanks to the protection against self-destruction caused by running out of water or clogged hoses, the protection of plants against overwatering and the additive function of fertilization, i tis a compact solar irrigation system. The last part deals with the testing of the created equipment and the analysis of the achieved results.

Organic materials for photonic applications
Kubíček, Václav ; Heinrichová, Patricie (referee) ; Weiter, Martin (advisor)
The bachelor's thesis focuses on characterisation of optical properties of substituated diphenyl-distyrylbenzenes for their potancial aplication in organic photonics. Dependance of molecular structure, used solvent and form on optical properties was studied. The theoretical part consists of research about current situation in organic photonics, it focuses mainly on organic photovoltaics. Results show that optical properties fundamentally depend on electronacceptor power of substituated group. Optical properties are also influenced by used solvent.

Energy retrofit of a stand-alone house
Stupka, Jaroslav ; Pech, Ondřej (referee) ; Charvát, Pavel (advisor)
The aim of the master’s thesis was to design heating, ventilation and cooling systems and to evaluate possibility of using renewable sources in case of a reconstructed two-storey family house. Air to water heat pump and floor system were designed to ensure both heating and cooling supply in the building. A heat recovery ventilation system was proposed. Gains of electrical energy from photovoltaic array were calculated and then possibility of coverage the heat pump consumption was evaluated. The thesis contains required calculations including building heat losses, heat gains, air exchange rates and the dimensioning of all mentioned systems. Technical drawing is also comprised.

Recording Studio with Accomodation
Fiala, Jakub ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
The main aim of this master’s thesis is to design a recording studio in a place of an abandoned agricultural building in a small village called Radešín. The thesis is structured into three parts. Goal of the first part is creation of a design documentation of architectural and structural designs. The building will consist of two storeys, a cellar and a gable roof. The most used building material will be reinforced concrete. Recording studio will offer three recording rooms accompanied by a large control room. Accommodation will include five apartments for ten inhabitants and a common room with kitchen. The second part is focused on design of selected building services. The building will be equipped with an air-to-water heat pump and wood chip boiler for heating. A mechanical ventilation with heat recovery will provide fresh air. Heat pump will also work as a cooling source. Furthermore, designs of the rainwater treatment, water heating, lightning and photovoltaics on the roof are included. The third part revolves around the matter of room acoustics. It describes basic knowledge and terminology of this field, which are then used to solve reverberation. I dealt with three variants – initial state, state with additional dampening and state with additional dampening with movable acoustic panels. One calculation was made in Microsoft Excel, the other one with help of room simulation in Odeon. Finally, I compared these two methods.

Monitorng of the photovoltaic power plant
Střípek, Martin ; Kunovjánek, Miroslav (referee) ; Dolenský, Jan (advisor)
This Bachelor work is dealing with theoretical knowledge of Photovoltaic. One of the great advantage of Photovoltaic is inexhaustible resource in long-time period – The Sun. This approach is especially important in todays world when more and more countries are becoming energetically dependent and may run out of fossil fuels. Bachelor work shall introdukce the principle of Photovoltaic, it's practical use for photovoltaic power stations, further it’s classification and types of constructions. The practical part is focused on monitoring the operation of photovoltaic power. Evaluate the instantaneous AC power, the total energy supplied to the network and compared with theoretical values. Bachelor thesis should help in detecting errors that can lead to energy losses.
