Document Generation System for Energy Optimization
Hrabě, David ; Zaklová, Kristýna (referee) ; Hynek, Jiří (advisor)
The goal of the thesis was the design and implementation of software for the company Optimal-Energy.cz, a.s., which automatically proposes measures for optimizing the resource consumption of buildings, especially the installation of photovoltaic systems and heat pumps. Based on the calculations, it generates documents that inform the customer about the proposed optimizations and contain the necessary contracts for performing the installation. The approaches to document creation and the possibilities of its automation have been analyzed. The original energy optimization calculations have been simplified and unified to operate on a common model based on the performed analysis. The solution was then implemented in the .NET environment using the F# and C# programming languages.

Possibilities of using a photovoltaic system in a family home
Herník, Martin ; Linda, Jakub (referee) ; Toman, Filip (advisor)
This bachelor thesis deals with the design of a photovoltaic power plant that will meet the needs and conditions of a specific family house. The design includes photovoltaic options such as battery and non-battery system solutions. In this work, the selection of appropriate components was made, where the emphasis was on achieving optimum system performance and minimizing costs while maintaining given efficiency and reliability. Finally, the economic evaluation of the two solutions in terms of cost and paybacks is assessed. The final design is proposed in the light of the current energy price situation and the continuous forward movement of PV technology.

Photovoltaic system for a family house
Hájek, Vojtěch ; Gregorovičová, Eva (referee) ; Toman, Filip (advisor)
This bachelor thesis explores the utilization of a photovoltaic system to reduce a family house's dependency on external electricity supply and achieve financial savings. Within the design section of the thesis, specific concepts of photovoltaic systems were developed. The primary objective is to minimize electricity costs while maximizing the use of renewable energy sources. These concepts are designed to achieve a major, rather than complete independence from grid electricity. Furthermore, the proposals were compared based on financial requirements, energy yield, and potential savings. The obtained results allow for the identification of a suitable proposal for a specific family house based on its energy needs and the owner's financial capabilities. Additionally, the study demonstrates the impact of subsidies on the overall return on investment in the project.

Utilization of natural resources for a garden greenhouse
Šplíchal, Jan ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The thesis performs the analysis of the potential of using natural resources, specifically solar radiation and rainwater, for garden greenhouses of various sizes, using self-created balance calculation tools and calculations made by them using available meteorological data. At the same time, the thesis provides a comprehensive overview of the technological possibilities of photovoltaic and irrigation systems in the context of garden greenhouses. The results of the calculations show that appropriately designed technological solutions can effectively ensure sufficient electricity and water for the autonomous function of the system. For smaller greenhouses, a simple photovoltaic system with one panel of about 0.5 m2 and a battery with a capacity of 300 Wh is sufficient for normal seasonal operation. For medium-sized and larger greenhouses, it is necessary to consider the optimal number of panels and batteries with regard to operational needs and the length of the season, but the number of panels and batteries is also acceptable in this case. For the irrigation system, it is important to consider the capacity of the barrel, which should be proportionate to the way the water is used. If the primary use of drip irrigation is being considered, then the performed analyzes show that a barrel capacity of 100 liters should be sufficient even for the needs of larger greenhouses.

Analyses of properties of photovoltaic inverters
Melichařík, Martin ; Vyroubal, Petr (referee) ; Vaněk, Jiří (advisor)
The thesis deals with photovoltaic systems with a focus on photovoltaic inverters. Solinteg, a company with a growing clientele, needs to set up a workstation to analyse PV inverters and systems at their branch in Brno for the European market. There are different types of system using different inverters and so the analysis for a particular system or inverter may be different. For a thorough analysis of these systems, special laboratory equipment is required, such as special power supplies and loads to simulate fault or operating conditions, complemented by measurement tools such as a power analyzer.

Financial return of home photovoltaic power plant
Jančík, Josef ; Malý, Milan (referee) ; Mauder, Tomáš (advisor)
This thesis if focused on return on ivestment evaluation of a photovoltaic system of residential house. The calculation is made for photovoltaic system with and without accumulation and in combination with other alternative source – heat pump. The costs of instalation and working of new systems are then compared between each other and with the cost of working of a current system without photvoltaic.

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.

Design of a photovoltaic power plant for a family house near Jihlava
Dvořák, Vít ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the design of a photovoltaic solar power station for a specific family house in the Jihlava region. The aim of the work was to get acquainted with technologies about the production of solar systems, evaluate the market in the Czech Republic and create a design of photovoltaic solar power station. Three designs of power stations were created with the help of the PV * SOL design system. Each design uses different photovoltaic cell technology. The result of each power station design is a complete finished project, which is based on many factors such as the efficiency of the entire system in a certain location, financial analysis, return on investment and more. In addition, these projects meet the conditions for the preparation of the subsidy program Nová zelená úsporám. At the end of the work, all three designed power stations are evaluated and with the help of multicriteria analysis, the best and most advantageous power station design for the given locality is determined. In the end, the idea of further development of the project is presented.
