Comparison of Connection Conditions of Photovoltaic Systems in the Czech Republic and the Slovak Republic
Vašica, Radoslav ; Radil, Lukáš (referee) ; Paar, Martin (advisor)
The objective of this work is an analysis and a comparison of legislative conditions of the connection of the photovoltaic power station on the territory of Czech Republic (CR) and Slovak Republic (SR). Presented are the working procedures for connecting of the power station to Distribution Grid (DG) and requirements of individual documents needed for a successful connection. Listed are also circumstances, which are taken into account during the consideration of the influence for connection, for the safe operation of DG. In the work are discussed the ways of support of constructing buildings of the photovoltaic power plant and the principle of repurchasing energy from renewable sources. The other part of work deals about hybrid photovoltaic power stations (HPPS), thus allowing to the power station to save energy into accumulators. There are the composition and principle of operation of the hybrid power stations. The following part deals with options of connectivity with hybrid power station to the DG. There are explained the advantages and disadvantages of connected and unconnected hybrid power plants to the DG.

Influence of RES to power system in Czech Republic
Vánišová, Michaela ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
This text deals with renewable energy sources in terms of working on the electricity network of the Czech Republic. There is the definition of renewable energy sources in the work. Next there are discussed the basic information about connecting to the distribution network. In two parts, there is mentioned and discussed the issue of operation of renewable energy resources and their effects in terms of the electricity network. The last chapter is focused on the possibility of further utilization of renewable energy sources because of their natural energy.

Cogeneration influence on power industry and power market in Czech Republic
Dudáš, Michal ; Cerman, Marek (referee) ; Macháček, Jan (advisor)
The main goal of this master’s thesis is to find out the impact of future development in combined heat and power technologies, especially the impact on power market in Czech Republic regarding to historical development of photovoltaics and subsidy policy. There are three scenarios of installed power growth designed including calculations of renewable energy source financial fee as well as overall evaluation. The paper also deals with current status of combined heat and power technologies in Czech Republic, European Union and USA as well as legislature framework of CHP in Czech Republic and EU. There are also kinds of state grants described. In economical part of the paper there are NPV’s of particular cogeneration units calculated. The calculations were made both with current investment costs and reduced investment costs.

Cogeneration plants on vegetable oil
Macoszek, Pavel ; Baxant, Petr (referee) ; Radil, Lukáš (advisor)
The thesis is focused on cogeneration units on vegetable oil. The first chapter contains basic information about the production, supply and consumption of electric energy in the Czech Republic and about renewable energy sources. The following chapter is devoted to possibilities of use oil kinds of phytomass in the Czech Republic, or products made from them. Next chapter is mentioned on legislation allowing the use of used cooking oils for energy purposes. It contains a summary of the laws and regulations and options regarding subsidies for electric and heat power. The main objective of these chapters is to explain the issue of the establishment and operation of cogeneration units on vegetable oil. The following chapters are devoted to the design and study of simultaneously operated cogeneration unit on the vegetable oil with a combustion engine and the calculation of economic operation running. The reason of study is to evaluation, which on based of the input values and calculation methods determine the economic efficiency of the project cogeneration unit on vegetable oil under mode purchase price and mode green bonus. Appreciation is also given to the overall legal review and responsibilities of cogeneration units on vegetable oil.

Characteristic of photovoltaic system
Pokorný, Marek ; Dolenský, Jan (referee) ; Vaněk, Jiří (advisor)
The aim of this work is informed first about photovoltaics universally, works to inform the photovoltaic panels and complete plants. The work also includes instructions on how to implement PVP in accordance with law. Another part is the rough draft of the photovoltaic power 30 kWp, which can be placed on the house, computation and calculation of investment and them profitable investments to time. Design is made in two separate forms of the Fronius Solar and Sunny Design, their outputs are compared. The practical part of this work cooperates with the company SOLARTEC Ltd. for experimental measurements of the photovoltaic system and develop a methodology for setting the properties of real solar systems in operation from the measured data then stored in a database. These data further evaluate and compare the similar operating conditions. This data will show as the course of production of electricity during the typical day in percentage terms, depending on the incident irradiance, cell temperature, angle of incident radiation, etc. We can compare what it looks like an ideal day in terms of production of photovoltaic power, with the other days. Further are in work mentioned histograms achievement panel behind classical day and behind all - time investigation.

Effect of changes in legislation on the profitability of business in solar energy
EIBLOVÁ, Pavla
The main goal of my bachelor work is the characteristic of photovoltaics (solar energy) and its legislation. In the first part I have studied information about photovoltaics in Czech Republic and information about the operation of solar power plants and its types of supporting. The main theoretical part of the thesis is the collection of all laws related to solar energy, including the interconnection of individual laws to others, especially to the standards set by the European Union. Furthermore, I will describe the development of legislation during the years 2010 - 2012, which will be viewed in chronological order and actually collected from various sources in the form of short messages or selected passages of law and adapted to an effective review. The goal of the practical part of the thesis is to introduce the concretely selected photovoltaic power plants and to determine the impact of the "solar tax" on their business. I have used the chosen methods of financial analysis, value and bankruptcy models and profitability to analyze the impact caused by the changes in legislation. Last part is dedicated to review the achieved results.

Business plan
Kočí, Pavel ; Krause, Josef (advisor) ; Hladký, Jan (referee)
The field of photovoltaics and solar power stations in the Czech Republic have experienced a huge developement in the past years thank's to very favourable conditions for enterprising in this line. These ones have changed a lot from the year 2011 and caused large changes in the photovoltaics. This thesis deals with business plan focusing on realization of minor solar power station. The main goal of this thesis is to compare on the basis of indicators of efficiency investment appraisal the real project from the year 2010 with the same fictitious project from the year 2011 and thus to show the impacts of legislation changes which should prevent from further growth of solar power stations in the Czech Republic. In this work photovoltaics is presented also generally so that it could provide comprehensive view of this branch.
