Thermovision of photovoltaic modules automatic analysis
Repko, Ilia ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
This work deals with the automatic evaluation of thermographic images of photovoltaic modules. In theoretical part of work described main principles of sun's battery work and methods for detection defects, that affecting the quality work, including method thermography, which is based on principle of contactless measuring the surface temperature the observed object. Practical part dedicated to creation of algorithms for detection defects, result is a source code for the program MATLAB.

Datalogger of environmental values
Raichl, Petr ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The thesis is aimed on construction of solar panel powered datalogger of environmental values. The thesis begins by research of commercial dataloggers. Then the concept of datalogger was created. Then the electronics of datalogger was designed. Datalogger is built as a system driven by microcontroller. The microcontroller reads data from sensors, writes data to memory card and sends data to Czech radiocommunications cloud by LoRa technology. Then the data are resend to MySQL database. Program for microcontroller was made in C language. Configuration of datalogger is done through USB interface by PC application which was created in C# language. For visualisation of measured data ASP.NET Core application was created.

Simulation of I-V characteristic on photovoltaic modules
Jiřík, Jan ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
Tato práce se zabývá slunečním zářením, které je jedním z možných zdrojů obnovitelné energie. Hlavnímy body práce je seznámit se s problematikou fotovoltaiky. Sestrojení poloautomatizovaného měřícího pracoviště díky němuž obdržíme reálné I-U a P-U charakteristiky solárního panelu. Dalším bodem je sestrojení programu v programu Vee Pro 8.0, který tyto charakteristiky simuluje v programu. Cílem je zjistit charakteristické konstanty pro daný solární panel.

Controll Electronics for Effective Supplying of Equipment with Li-Ion Accu by Solar Cells
Horký, Luděk ; Dřínovský, Jiří (referee) ; Urbanec, Tomáš (advisor)
This Bachelor`s thesis deals with questions surrounding the collection and harnessing of solar radiation for use as electrical energy. The aim of this project was to build an effective system for charging Li-Ion batteries by means of solar cells. To this end, four different solar panels currently available were chosen for measuring and evaluation. The most suitable of these was chosen and an electronic control system devised for effectively supplying the Li-Ion batteries. It was necessarily to make solution for problems consequent upont this method of charging this type of battery and make practise realizitaion of this electrical scheme by SMT technology.

Monitorng of the photovoltaic power plant
Střípek, Martin ; Kunovjánek, Miroslav (referee) ; Dolenský, Jan (advisor)
This Bachelor work is dealing with theoretical knowledge of Photovoltaic. One of the great advantage of Photovoltaic is inexhaustible resource in long-time period – The Sun. This approach is especially important in todays world when more and more countries are becoming energetically dependent and may run out of fossil fuels. Bachelor work shall introdukce the principle of Photovoltaic, it's practical use for photovoltaic power stations, further it’s classification and types of constructions. The practical part is focused on monitoring the operation of photovoltaic power. Evaluate the instantaneous AC power, the total energy supplied to the network and compared with theoretical values. Bachelor thesis should help in detecting errors that can lead to energy losses.

Solar Powerstation Web Interface
Škvařil, Radek ; Michal, Bohumil (referee) ; Lampa, Petr (advisor)
This thesis is focused on practical usage of solar energy in photovoltaic systems and on the Fronius product portfolio. It is also focused on implementation of web interface for modular solar photovoltaic Fronius powerstations system. It is purposed on displaying statistic data, drawing charts and solar system monitoring. This system is desired to act autonomic and self-configurable. System will be implemented using the PHP5, MySQL4 technologies and object oriented programming technique.
