Determination of climatic factor on the degradation of various solar cells types
Peroutka, Tomáš ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
In this work are discussed photovoltaic cells. There are also discussed basic concepts of radiation source for solar cells. Also mentioned the issue of semiconductors and even the history and evolution of the solar cells. A large part deals with possibilities of photovoltaic cells degradation. In one chapter is an attempt to bring some types of photovoltaic cells and a description of the production of these modules.The practical part deals with photovoltaic modules degradation and its evaluation. Following part compares measured values with the values provided by producer of photovoltaic modules.
Energy yields per one hectare of land in the South Moravian Region
Plášek, Tomáš ; Bayer, Robert (referee) ; Jandová, Kristýna (advisor)
This bachelor thesis compares methods of producing elektricity in biogas plant, in thermal power plants by burning biomass, in solar power plants and compares it with production of energy of fuel cells and the energy from biofuels, like biodiesel and bioethanol. It compares the energy yields of different energy production methods and evaluates their advantages and disadvantages. It compares the energy content of these fuels by model vehicle range.
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.
Support of company management systems using available software tools
Panák, Petr ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
Successful organisations are build upon effective management systems based on general values, concepts and processes, described not only in standards. While standards represent general requirements, area of expertise demands specific requirements. In both cases management systems are supported by suitable software tools making collaboration and workflow easier. The thesis focuses on correct evaluation of software tools adhering to relevant requirements of ISO standards. General evaluation criteria are outlined and then specified. Evalution approach, method and guide are created. Table and database editors are considered as possible evaluation tools. As an example, tools for organisation management support are evaluated. The practical part of the thesis describes a specific organisation and its needs for document and internal audit management, from which criteria, evaluation method and recommendations are drawn. At the end is described the counselling procedure.
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.
Characterisation solar cell electric properties by CCD camera
Steiner, Patrik ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
The aim of this thesis is the characterization of electrical properties of solar cell using CCD camera. Diagnostic methods are based on electroluminescence and microplasma emitted from the surface of the solar cell. The results are then compared with the method LBIC (Light Beam Induced Current) and described the various defects in industrial production.
Energy yields per one hectare of land in the South Moravian Region
Plášek, Tomáš ; Bayer, Robert (referee) ; Jandová, Kristýna (advisor)
This essay analysis problems of photovoltaic power plant operation and production of elektricity from biofuels. It also compares energy yields from different types of biofuels with yields of energy from solar panel.The essay also evaluates consumption of these fuels and efficiency of powering cars with combustion engine against electrical car.
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 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.
Long-term influence of low-flammable electrolytes on negative electrodes
Valoušek, Michal ; Jandová, Kristýna (referee) ; Máca, Josef (advisor)
