Backup power supply with solar panel charging
Křepela, Pavel ; Götthans, Tomáš (referee) ; Kubíček, Michal (advisor)
This project aims to create a backup power source with solar charging for small mobile devices (through USB connector). The charger should store power in a battery that is charged either from external power source or the solar panel. In the introduction, the work deals with the theory of solar cells and batteries. Furthermore, it described the selection of suitable components and design diagram.

Quantification of energy contribution of solar system control unit
Míčková, Petra ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
The aim of this work is to study the problems of solar energy and its use in solar systems. Furthermore, to become familiar with a particular solar system for hot water, especially with the principle of energy conversion and features individual components. It is designed and implemented measurement method to determine whether the control unit for the system is important, or would be better even without it.

Design of a photovoltaic system and its economic evaluation
Hausner, Josef ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This Bachelor’s thesis deals with design of the photovoltaic system on a roof of a prefabricated house. In the theoretical part the current technology of photovoltaic cells and panels is analyzed. The next part clarifies current legislative conditions in the Czech Republic. A photovoltaic system is designed in the practical part. In the last part, the project is economically evaluated using a method of the net present value and the internal rate of return.

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.

Use of solar energy in CR
Krištofík, František ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
The work deals with the use of solar energy as one of renewable energy sources, hence the possible successors to fossil fuels in the energy future, present, looking at solar energy and its energy position in the world today. It addresses the possible advantages and disadvantages of using solar energy. It brings thoughts of the ecological and economics and suggest possible compromises. Next part is focused on the use of the climatic conditions of the Czech Republic and compares the efficiency of solar collectors and photovoltaic panels.

Combined use of solar energy
Zeman, Miroslav ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
This thesis focuses on the combined use of solar energy. The solar conditions in the Czech Republic are listed in the first part. Further, there is the classification of solar collectors focusing on certain types and detailed description of the solar system scheme. The second part discusses the principle of photovoltaic and its historical development considering panels from the first mentions up to the present. The third part is aimed at the selection of the appropriate object and determination of its power consumption. The following chapter discusses the appropriate connection of the photovoltaic systems, the first connection containing only one inverter, the second containing two low-power invertors. The chapter also contains the connection of the solar system and a description of the individual components considering all schemes. The last chapter includes the technical-economical assessment of the whole project and the calculation of the payback period in case of photovoltaic systems.

Barriers of renewable sources expansion in the Czech Republic
Lukášek, Kamil ; Březina, Ladislav (referee) ; Mastný, Petr (advisor)
Currently, there is no publication that concerns the renewable resources comprehensively in the Czech Republic. This publication defines the renewable resources in general meaning. Whereas the physical and legal definitions of the renewable resources are different, text explains the principle of production of electricity according to the legal definition. When the renewable resources are being constructed, it's important to achieve the optimal operating conditions. To achieve these conditions, it's necessary to locate the renewable resource in the Czech Republic. The operations of renewable resources are partly financed by the country, in order to be more interesting for the investors. Further on, the conditions of connection to electrical distribution system are defined. The impact of renewable resources on electrical distribution system. Finally the conception of renewable electrical energy resource for region of East Bohemia is designed.

Low potential heat for electrical power generation
Dobiáš, Jiří ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor’s thesis deals with low potential heat sources for electrical power generation. It mentions primarily low potential heat sources, their distribution by origin and where you can find such resources. Another part deals with the technology that uses low potential heat to heat production of higher temperature level and power generation. These are discussed here with a heat pump, regenerative heating, Stirling engine, solar collectors, Peltier cells, etc. In addition is to their use in practice. The last chapter deals with the replacement of the heater in the regeneration heating coil from the solar collectors. It is thus the use of renewable energy sources. Carry out technical and economic calculations for the real utility of such a plan.
