Photovoltaic Power Plant Return on Investment Model
Skoupý, Ondřej ; Slavinský, Vojtěch (referee) ; Doubravský, Karel (advisor)
This master thesis focuses on the design of a model for estimating the initial investment cost in constructing a photovoltaic system and assessing its payback. The thesis includes an analysis of the electricity consumption behavior of selected households and an assessment of the critical input parameters necessary for designing the photovoltaic power plant system. Based on the data obtained, a model has been developed, the capabilities of which have been demonstrated in the example and are further discussed within this thesis. The model enables efficient preparation of quotations and payback analyses, which brings significant benefits to streamlining photovoltaic power plant system pricing activities.

Detection and Classification of Photovoltaic Power Plant Panel Defects from a Drone Thermal Imaging Camera
Haužvic, Filip ; Materna, Zdeněk (referee) ; Bambušek, Daniel (advisor)
The thesis describes the processing of thermal images of photovoltaic power plants captured by a drone. In contemporary solutions, the images are analyzed manually, where an expert in thermal imaging searches for defects in individual panels. This approach is very time-consuming, and introducing some level of automation could ease the process. Therefore, I trained and utilized a U-Net model that detects hot spots in the images. To visualize and present the defects to the user, I designed and created a web-based application that highlights them in a complete orthomosaic of the photovoltaic power plant. Within the application, a user can annotate PV panels in the power plant and manually remove, or add any defect. When the plant is wholly annotated, an export to a spreadsheet can be created, matching defects to the individual annotated panels.

Seasonal variation in renewable energy supply
Rymešová, Lucie ; Škorpík, Jiří (referee) ; Linda, Jakub (advisor)
This bachelor’s thesis focuses on seasonal fluctuations in energy supply from renewable sources, specifically photovoltaic and wind power plants. It includes a literature review on renewable energy sources and their importance in the energy sector. It further explores the principles and utilization of photovoltaic and wind power plants. The thesis analyses seasonal fluctuations in energy supply by processing data from the ČHMÚ station and examines their impacts on the energy system. The results of the analysis of seasonal fluctuations are presented and compared. It is evident that solar energy has the largest share during the summer months, while wind energy has the highest contribution during the winter months. The results suggest that a suitable combination of photovoltaic and wind power plants could suppress seasonal variations in electricity supply and contribute to its stable production within smaller energy units.

Support of the energy sources construction for households
Stručovský, Aleš ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor thesis deals with the comparison of energy sources used for residential construction. It focuses on photovoltaic power plants, wind power plants, hydropower plants and cogeneration units. Budget cost of energy source is limited to the amount of 550 000 CZK. Every source of energy is defined by its feature, operating principle, advantages and disadvantages. Options of selling the produced energy and its price are specified. Furthermore, the particular building licence applications (construction administration approval, generation of power questionnaire, application for connection to the distribution network, application for the contract of energy production support) including all the necessary enclosures have been analysed. Essential aspect for buying the energy source is its power and it is chosen according to the type of source. Energy source of hydropower systems is flow and gradient, in wind power systems it is wind speed, in photovoltaic power systems it is sufficient intensity of sunshine and in cogeneration units its dependance on annual heat consumption. Specific energy source available on our market is chosen for every group and the calculations of annual electricity production, period of repayment and profitability in 20-year running period are performed.
