Design of a photovoltaic power system with battery storage for household purposes
Lacina, Jaroslav ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
This master’s thesis takes a look at possible project of photovoltaic powerplant with power storage for households. The principle and function of photovoltaic cells, inverter and acumulators will be explained in the theoretical part. The subsequent part will focus on description of photovoltaic systems, legal point of view as well as funding by programme New Green Savings.In the practical part, the photovoltaic power plant with battery storage for the home and its economic evaluation is proposed. The PV*SOL premium program was used for simulation and data processing.

Draft methodology for processing and evaluation of long-term measurements on PV Panel
Žák, Tomáš ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This bachelor thesis aims to analyse the physical theory behind the photovoltaic cells and propose extension measurements for a modernised on-line laboratory. The first part of this thesis describes the theory of the photovoltaic conversion of solar energy into electricity. The p-n junction is described in detail because of its importance for a thorough understanding of the subject. The temperature dependence of a photovoltaic panel, i.e. the negative impact of rising temperature on the output power, is also described here. The contributions of this thesis include a summary of the current situation and the system of state subsidies for the current year as well as a proposal for an extension of measurements in an on-line laboratory, which is to be modernised, at the Department of Power Engineering. Therefore, the thesis includes some specific proposals of graphic dependence, which have a significant information value, and a possible further extension of the laboratory with new measuring and measured elements, which would be helpful for deeper understanding of the subject. In particular, it would be useful for understanding which factors influence the output power of a photovoltaic panel, both significantly and less significantly, which is undoubtedly the most important point.

Energy supply of mountain cottage
Flöhsler, Tomáš ; Martinec, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of this Graduation Thesis is to devise a system of energy supply intended to provide supply of electric and heat energy to a vacation property. The main feature of this energy supply project stands for a shift from mains power supply to alternative energy supply using renewable resources. The reason for this change is the fustiness of power lines and their negative effect on the surrounding landscape. Due to the fact that authorities did not permit renovation of these power lines, the only way to preserve the functionality of the vacation property is to secure its power supply by employing renewable resources. The vacation property (a mountain cottage) is located in Hrubý Jeseník Mountains, approximately 15 kilometers from the town of Šumperk. The thesis also contains a description of the way outlying settlements are currently supplied with energy, including the possibility of accumulation and a brief description of each electrical appliance’s power consumption. In the design itself, I calculated the necessary collector surface and analyzed the most effective collector placement. As for the wind energy system, I had to found the best spot to place the turbine. Last but not least, the thesis contains the technical-economical comparison of the proposed alternatives.

An assessment of returnability of solar collectors installation in low-energy family house
Hrbata, Jiří ; Pešek, Martin (referee) ; Jaroš, Michal (advisor)
Increasing of standard of living, automation and mechanization of production and industrial growth lead into energy need growth. At the same time the energy prices continuously rise and it is still more preferable to use renewable energy, particularly solar radiation. This thesis contains basic information about usefulness of solar radiation, solar collectors and ways of their integration into heating systems. Particularly, it deals with the assessment of returnability of solar collectors instalation in the low energy family house. It contains calculations of necessary heat for heating, hot water heating and energy gains from solar collectors. Returnability assessment is demonstrated on concrete example.

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.

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.
