Automatic Positioning for Solar Concentrator System
Čásar, Juraj ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The aim of the work was to create an automatic positioning system, with optics for radiation concentration and a body for its collection, by monitoring the sun across the sky using a camera. At the beginning are introduced the concentrator systems and the movement of the sun from the perspective of the observer. Follows description of the various potential components which requires a functional system. The last part deal with the implementation of selected components for operation as a whole system, verification of functionality by accurate tracking of the sun across the sky and measuring the performance of the concentrator system with automatic positioning.

Solar Concentrator System with Automatic Tracking System
Žák, Martin ; Sumec, Stanislav (referee) ; Baxant, Petr (advisor)
This master’s thesis is focused on current possibilities of solar energy utilization – especially on concentrating solar power systems – and their optimization using solar tracking systems to maximize energy gain. The thesis also deals with solar position algorithm and offers an Arduino based automatic dual axis solar tracker design which provides various solar devices the ability to pivot using stepper motors, DC motors or servos. The motion might be driven by calculated solar position or by actual illuminance.

High temperature energy reservoir with year-round operation in conjunction with a solar system
Hoc, Pavel ; Šikula, Ondřej (referee) ; Hirš, Jiří (advisor)
In this thesis I deal with the issue of stand-alone solar system development. This system ensures the supply of all the energy needed for a reference house. It consists of a solar concentrator and a heat reservoir. I used mathematical models to solve this issue. The calculations showed, that the concentration of solar radiation into the heat reservoir can usually achieve 69 % efficiency. The efficiency can be even higher when using a very reflective materials of the solar concentrator. In this thesis, the thermal reservoir is described and its improvements are suggested based on the optimization calculations. Thanks to knowledge gained during solving this issue, a prototype of the stand-alone solar system is going to be built. All findings will be experimentally verified with this prototype.

Solar Applications with Concentrator Elements
Hrachiar, Róbert ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The subject of this bachelor thesis are solar applications with concentrator elements. In the thesis are described theoretical knowledges of various types of concetrator systems, development history, separation, system description, economy and usage of concentrator systems. Basic information about solar irradiation, which is useful for concentrator systems, it's separation and the possibilities of using in our enviroment are also described in the thesis. In practical part is designed model of solar concentrator, a description of realization and following measurements on constructed model.
