Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.

Power optimizer design for on-grid photovoltaic systems for family houses
Trenčanová, Bianka ; Procházka, Petr (referee) ; Cipín, Radoslav (advisor)
This thesis deals with hardware design of an optimizer of energy flow from photovoltaic power plant to prevent an overflow of power made by plant to grid in grid-on system in case of excess of made energy. Theoretical part is aimed at photovoltaic, types of photovoltaic power plants and situation in Slovakia and Czech republic. Practical part is about designing the energy flow optimizer. It describes its main parts with descriptions of components' features, partial connection diagrams and finally connection diagram as a whole.

Comparison of Connection Conditions of Photovoltaic Systems in the Czech Republic and the Slovak Republic
Vašica, Radoslav ; Radil, Lukáš (referee) ; Paar, Martin (advisor)
The objective of this work is an analysis and a comparison of legislative conditions of the connection of the photovoltaic power station on the territory of Czech Republic (CR) and Slovak Republic (SR). Presented are the working procedures for connecting of the power station to Distribution Grid (DG) and requirements of individual documents needed for a successful connection. Listed are also circumstances, which are taken into account during the consideration of the influence for connection, for the safe operation of DG. In the work are discussed the ways of support of constructing buildings of the photovoltaic power plant and the principle of repurchasing energy from renewable sources. The other part of work deals about hybrid photovoltaic power stations (HPPS), thus allowing to the power station to save energy into accumulators. There are the composition and principle of operation of the hybrid power stations. The following part deals with options of connectivity with hybrid power station to the DG. There are explained the advantages and disadvantages of connected and unconnected hybrid power plants to the DG.

Project of the construction photovoltaic power plant
Mačugová, Radana ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The objective of this thesis is to analyze and evaluate the profitability of photovoltaic power plant construction project. The introductory part deals with general characteristics of solar energy and its utilization, with the Slovakian and the European legislation in connection with use of renewable energy resources. The practical part deals with solar energy from the perspective of private firm. One particular company is considering about the implementation of photovoltaic power plant. This section begins with the presentation of the private company and evaluation of its preconditions for this planned construction. The thesis also describes planned implementation of the project, namely its preparation, possibilities of obtaining funds, necessary communication with the public agencies, selection of technology and the construction itself. At the end is project evaluated from the point of profitability by selected indicators.
