Utilization of renewable energy sources in Czech Republic
Kopička, Marek ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This thesis deals with consideration of energy facilities structure in Czech Republic. It is depicted in it their evolution from point of: electric energy consumption, structures of energy facilities and electricity prices. Further, is here depicted a production of electric energy for the year 2009, from the point of: produce, sources, consumption and ratio of factories. Of course, the RSE (renewable sources of energy) effect and share of scope on this evolution and structure, is also mentioned here. The next part is pointed to basic description of each sources of electric energy. It is not mentioned here only factories which uses for it´s production renewable primary sources but also another types of factories. Their pros and cons are also summarized. The last part of this work is a thought of realization of fictive project, which could replace a part of steam power plants' share by producing electric energy through renewable sources. It is re-counted and suggested here a few possibilities of this realization from the point of needed installed power and approximate estimation of capital expenditure.

Conversion efficiency of various means of electricity production from solar radiation
Wolf, Juraj ; Tuhovčák, Ján (referee) ; Charvát, Pavel (advisor)
The subject of bachelor thesis contains various methods of converting solar energy to electricity. This study analyzes their conversion efficiencies, potential growth and versatility. Considered technologies are photovoltaic and concentration solar system. Thesis reviews new trends for enhancing conversion efficiencies for both methods and evaluates their potential for future depending on their achieved efficiency, power output, maintenance requirements, climatic condition and demand for addition equipments needed for their application.

Pension
Koršala, Martin ; Řezníček, Petr (referee) ; Hradil, Dušan (advisor)
The subject of this final thesis is the preparation of a project documentation for the building construction of a new pension with restaurant and wine cellar. The compound is located in Vážany nad Litavou. Its location falls under Velké Pavlovice area. Due to the location in this wine-growing region is in the project located, a wine cellar with a vineyard. The project is designed as a guesthouse with the restaurant designed for families with children, and for holding small social or company events. For this purpose, is in the main building designed a lounge with capacity of 20 people and a restaurant with capacity of 60 persons. The accommodation capacity provided in the pension is 43 beds. Pension offers background designed for relaxation or wellness stays thanks to the sauna and whirlpool. The building has rectangular plan on two basements and two above-ground floors with a mono-pitched roof facing south. This makes it possible to use solar power from the roof and south-facing facade. Water from the roof of the building is collected in a small pond, which serves as a storage reservoir useful in case of fire and vineyard irrigation. Near the building there are paved and parking areas.

Connection of Solar Power Plant and Water management
Zajíček, Michal ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
In the bachelor's thesis Connection of Solar Power Plant and Water management the author designs the technical solution of pump control using solar energy. The main reason is to make an automatic system for pumping the rainwater through filters due to increasing its quality. Powering the device with a solar power plant will reduce the energy requirements and will also make it possible to store surplus energy from the solar power plant into the potential energy of the water. The result of the work is the compact device with an automatic control system designed to control small 12 V pumps, theoretical design of the photovoltaic power plant to power the device and theoretical analysis of solar energy and water management issues.

Renewable energy sources for one-family house
Burýšek, Jan ; Špiláček, Michal (referee) ; Fortelný, Zdeněk (advisor)
This Bachelor´s Thesis deals with the topic of Renewable Energy Resources. It is divided into two main parts. The first part is a research on renewable resources of energy which are available in the Czech Republic. The second part is focused on use of particular resources in a chosen object (house) and their subsequent efficiency evaluation.

Operational efficiency of photovoltaic generators
Koval, Filip ; Václav, Březina (referee) ; Gregor, Jan (advisor)
Objective of master’s thesis theoretical part is especially to illustrate influence of operation conditions, such as solar radiation, temperature or pollution of photovoltaic generator active area, on load and power characteristics of photovoltaic generator, or more precisely on photovoltaic conversion efficiency. Possible variants of increasing effectivity of using photovoltaic generator are explored, such as solar radiation concentration, photovoltaic generator active area cooling or aplication of optimalization circuit. Pivotal part of master‘s thesis is focused on experimental device practical realisation, concretely type MSQ36-10 photovoltaic generator with oriented concentrators of solar radiation. Practical realisation includes design of master‘s thesis experimental part construction with subsequent design of photovoltaic generator motion cycle necessary for adequate simulation of configuration variants solved using single testing photovoltaic generator. Description of own experimental device construction with list of measuring places used in task takes up. It is used automatic monitoring system working as independent measurement task for required values measuring and consecutive data collecting. It is done in two phases. First phase is measurement of all required values, in second phase measurement with attached optimalization circuit is made. Optimalization circuit sets best working point of photovoltaic generator according to actual working conditions. Master‘s thesis intention is experimental verification of solar radiation concentrators application convenience, orientation of photovoltaic generator or its mutual combination, namely using type MSQ36-10 photovoltaic generator. Objective is evaluation of reached energetic gain for all experimental device layouts in variable operating conditions.
