Comparison of photovoltaic and photothermal systems for hot water heating in an apartment building
Švéda, Richard ; Lachman, Jakub (referee) ; Toman, Filip (advisor)
This bachelor's thesis examines the comparative merits of photovoltaic and photothermal systems for domestic hot water heating. The introductory section provides an overview of solar radiation, its origin, and its striking the Earth´s surface. Thereafter, both systems are subject to detailed analysis and calculations. These systems are designed for a specific residential unit and evaluated from technical, financial, and operational perspectives. Based on these calculations and analyses, the most suitable choice for the given location is recommended.

Switch board for FVE design
Kovář, Lukáš ; Holek, Radovan (referee) ; Kaczmarczyk, Václav (advisor)
This thesis focuses on electrical switchboard design and optimalization for a photovoltaic power plant. Within the design, the main requirements for the switch board, such as the output voltage of photovoltaic panels, the ability to monitor power, protection against external influences, and the output system, are defined. Thesis‘ key element is the implementation of modern technologies and control systems for power monitoring and control. The thesis explores the possibilities of using automation technologies for optimal energy utilization and maintenance costs reduction.

Simulace fotovoltaické elektrárny v rodinném domě
Gabrys, Adam ; Zachariáš, Michal (referee) ; Szőke, Igor (advisor)
This work deals with the simulation of a photovoltaic power plant system for a single-family house with subsequent optimization with respect to the return on investment. It emphasizes the visualization of the results and the possibility to include custom photovoltaic assemblies including inverter, photovoltaic panels and battery. The tool works with a three-phase system, where it is able to analyse the consumption of each phase and perform simulations with the power delivered from the solar panels. The optimization of the different components of the power plant is performed using a genetic algorithm. The simulation is implemented in Python based on object-oriented programming principles in order to allow the addition of new modules.

On-line calculators for the design of renewable energy installations
Ondráček, David ; Pospíšil, Jiří (referee) ; Linda, Jakub (advisor)
This thesis focuses on the field of renewable energy sources (RES). It focuses on the topic of computational tools that manage the design process of a system using RES. These tools are introduced, their calculation methodology is described and then they are evaluated. As a part of this thesis there is also introduced a design of a unique calculation tool. This tool calculates the energy balance of a dwelling using solar energy and a heat pump.

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.

Photovoltaic systems in the cities
Dobiáš, Pavel ; Procházka, Zdeněk (referee) ; Mastný, Petr (advisor)
This Bachelor thesis' main goal is to introduce a potential reader with the photovoltaic system questions and its utilization in many applications. In the leading chapter the thesis deals with the potential of the energy which is radiated from the Sun towards the Earth. It tries to analyze the common problems of using this energy. The next part deals with simple semiconductor operating principles and explain the principles of photovoltaic cell functions. The upcoming part deals with the construction and basic types of photovoltaic cells and show the possible ways in their development. In the next part there are analyzed many types of photovoltaic systems and their application in praxis. In the next part the reader is introduced with the meaning of photovoltaic as a renewable source and with its support in the European Union and Czech Republic. The last part deals with design of four devices which uses photovoltaic system as a power source and which can be used in the city agglomeration environment.
