Simulation of solar cells using in electrocars
Obadal, Petr ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The thesis deals with the question of the production of electric energy in electromobiles by the means of photovoltaic cells and its using. The thesis presents the model of photovoltaic system composed of the three photovoltaic fields incorporated in the electromobile model and it considers its maximum usable surface and efficiency. The thesis also includes the calculations concerning the charging time of accumulator, the amount of energy gained from photovoltaic fields – comparison of practical energy gain, the electric parameters in general and the overall performance of electromobile model. The aim of the thesis was to design an electromobile model which would serve as a model for actual-sized electromobiles using the renewable source of electric energy.

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.

Different way how to use solar radiation for the electric energy production
Obadal, Petr ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The thesis deals with the problem of potential use of solar energy through the conversion into electric energy. The thesis analyses in great detail several types of conversion. My special concern included photovoltaic conversion and thermal conversion of solar energy using steam turbines for energy production. In the subsequent parts, I focus on the problem of photovoltaic, photovoltaic systems, and solar thermal power plants, their installation and use.

Comparison of different photovoltaic panels in CR
Červinka, Pavel ; Stojan, Radek (referee) ; Pléha, David (advisor)
This term paper deals about history, principle and use of photovoltaic panel. It describes their stucture and constantly improving properties of these panels. It outlines their gradual generational evolution from beginning to present. Then it describes the various systems involved on – grid and off – grid. It also describes and compares the photovoltaic panels and inverters from different global manufacturer. The end of this work deals about conditions of photovoltaic in the Czech republic and about Hady photovoltaic incubator, which belongs to the company Energ servis a.s. It presents a comparison of different local and the analysis of the impact of shading for the achievement of the photovoltaic panel. It makes mathematic models for calculation of the spacing range and calculation the power loss in a specific shade.

Photovoltaic, as an alternative source of electricity
Floková, Kateřina ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is to provide a description and an explanation of the process of obtaining elektrical energy from solar radiation. There is preliminary mentioned an importance of producing electrical energy from renewable sources and development of photovoltaic systems. The body of the thesis is divided into seven chapters. At first, there is described the principle of transformation solar radiation into electrical energy. Then, the description of types of barrier-layer photocells follows. The types are divided according to their structure and material, which are they produced from. The third chapture is focused on production and construction of photovoltaic modules. Ways, how can be production of electricity increased, are mentioned in the fourth chapture. Advantages and disadvantages of solar concentrators are given there. In the fifth chapture there are described two basic kinds of connection of photovoltaic system. Different ways of taking-off produced electricity are related with those kinds of connection. The last chapture is the fundamental chapture of the thesis. There is given a project of concrete photovoltaic system. For this system is calculated economic return of investment included supposed increase of prices of electricity. In conlusion the author noticed events that would be given and emphasized the outcome of concerete project of photovoltaic system.
