Design of a kit for the creation of a supply point for electricity generated from renewable sources
Fridrich, Jiří ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
This project deals with the design and realisation of a set that will work as a power supply point with electricity generated from renewable energy sources. The theoretical part deals with information about renewable energy sources and energy storage options. In the practical part, a mobile kit for powering variable message traffic signs is designed. It uses photovoltaic panels and stores energy in a lead-acid battery. A methanol fuel cell is used for backup power. The device is adapted for use in road traffic and meets the requirements of the relevant authorities. To verify the stability of the structure, there were performed static calculations, which proved the ability of the device to withstand wind stress. Part of the work was to draw a complete production documentation, which was used to create a test sample. Long-term measurements of energy flows in the system were performed on that sample. These measurements confirmed the ability of the device to operate autonomously and the possibility of using it for the required purpose.

Design of a photovoltaic system and its economic evaluation
Hausner, Josef ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This Bachelor’s thesis deals with design of the photovoltaic system on a roof of a prefabricated house. In the theoretical part the current technology of photovoltaic cells and panels is analyzed. The next part clarifies current legislative conditions in the Czech Republic. A photovoltaic system is designed in the practical part. In the last part, the project is economically evaluated using a method of the net present value and the internal rate of return.

Analysis of energy supply for the complex of buildings Technicka 2
Šimková, Nikola ; Pospíšil, Jiří (referee) ; Brázdil, Marian (advisor)
The diploma thesis on the topic "Energy supply of the Technical 2 complex" deals with the energy supply of the Faculty of Mechanical Engineering of the Brno University of Technology. The area is a major consumer of energy and is dependent on supplies from the distribution system. At the beginning of the work there is an analysis of the current energy supply. There are two photovoltaic power plants in operation, which reduce electricity consumption. However, they were installed in 2006 and 2016, so their current performance must be analysed. The following section evaluates the technical feasibility of extending photovoltaic power plants to other building’s roofs in the area and then the final variant is evaluated from an economic point of view regarding the possible development of electricity prices. The possibilities of obtaining funds from the ongoing grant calls and future grant programs are also described.

MPPT regulator of photovoltaic power plant with smart battery management
Uhlíř, Marcel ; Boušek, Jaroslav (referee) ; Háze, Jiří (advisor)
The thesis deals with design of photovoltaic controller using MPPT technology based on Perturb & Observe algorithm extended by fuzzy logic processing. The converted energy is stored in a battery system with an optional voltage 12 V or 24 V. The battery system is provided by intelligent battery management, which allows to use a voltage balancer and desulphation. The whole system can be powered by external power supply, which is used to charge the batteries if there is the absence of photovoltaic energy. The device contains 12 V and 5 V outputs for connecting external devices. Through USB and Ethernet interfaces, it communicates with utility software that allows user to configure controller parameters and display battery system values. The purpose of this work is directed to the field of portable island systems for use in residential vans or caravans.

Energy gains of agrofotovoltaics
Huf, Milan ; Kudela, Libor (referee) ; Pospíšil, Jiří (advisor)
This master's thesis focuses on the possible synergy between agricultural activity and solar energy production. The theoretical part of this work begins with the processing of theoretical knowledge in the field of photovoltaics. Furthermore, the concept of agrophotovoltaics is explained, its advantages and possible types of installation are introduced. Furthermore, existing installations around the world are presented and the situation around agrophotovoltaics in the Czech Republic is outlined. The practical part of the work is focused on the creation of the model and its programming so that the panels create shade for cultivated crops. The conclusion of the thesis is devoted to the design of an agrophotovoltaic installation in the Brno area and the assessment of its technical and economic aspects.

Energy supplies fairgrounds
Foit, Vladimír ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis titled Energy supplies fairgrounds is divided into four parts. The first part is devoted to the theory of sources of froze and heat energy. The next part deals with current condition of energy supplies of fairgrounds. The third part is based on the design of possible adjustment of energetic management for both the whole compound and partial objects. The last part sums up all the adjustments and evaluates all the real variants by closer economic analysis.

Filtering structures for fotovoltaic power stations
Hruška, Petr ; Dostál, Tomáš (referee) ; Petržela, Jiří (advisor)
This thesis is dedicated to an issue of vibration of photovoltaic panels, which manifests itself primarily in the acoustic field. From the photoelectric effect is gradually getting through photovoltaic cell, panel, string, power plant to define the causes of the vibration. The aim of the work is to design electrical low pass filter that suppress disruptive elements, which prevents audible vibrations of panels and the whole system of photovoltaic power plants.

Long-term monitoring of parameters of photovoltaic modules
Kladiva, Roman ; Solčanský, Marek (referee) ; Gvritishvili, Roman (advisor)
This thesis deals with the influence of degradation mechanisms to change the parameters of photovoltaic panels. The aim of the study was the long-term monitoring of selected solar modules, comparing their parameters with measurements from previous years and the evaluation of degradation mechanisms on their properties. The theoretical part is focused on the description of the monitored parameters and defects Panel, are discussed measuring methods by which the modules were monitored. Experimental part then consists of measuring modules individual test methods. The measured values were subsequently constructed graphical dependence, and the results were compared with measurements from previous years. The last part of the thesis is devoted to evaluation of the degradation of PV modules.
