Solar systems utilization for family house energy demand
Šamanová, Jaroslava ; Toman, Filip (referee) ; Sitek, Tomáš (advisor)
Solar systems are more and more common part of residential houses. Main reason for this, is that solar elements are state-supported with subsidies, which is reducing payback time of these investments. At the same time, the prices for these systems are dropping. The state support is connected with effort to reduce dependancy on non-renewable energy sources, e.g. coal powerplants, which are polluting atmosphere. State administration i salso the reason for large scale solar powerplant constructions, which are, according to some opinions, misshaping the landscape and covering large areas of sometimes fertile land.

Design of ecological heating of a family house
Kořínek, Vladimír ; Máca, Josef (referee) ; Jandová, Kristýna (advisor)
This diploma thesis deals with the design of ecological heating for a family house. The main objective is to find the most advantageous variant of the heating and water heating system using a heat pump in cooperation with an alternative heating system. Thermal losses are calculated for the selected object, and several heating designs are made based on the calculations. Then the economic return of the designs is calculated.

Monitoring of air flow around photovoltaic modules
Herman, Michal ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the flow of air around photovoltaic modules and the associated effect on their temperature and overall performance. In the thesis, a device for sensing the mentioned quantities is designed and it is compared with similar types of devices in terms of price, dimensions and accuracy. Furthermore, the thesis describes the placement of individual sensors and sensing interval of quantities. In the second part of the thesis, long-term stored data are plotted in graphs and the extend to which they affect the photovoltaic system is evaluated.

Standard switchboard for PV plants up to 10 kW
Řezáč, Stanislav ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The bachelor's thesis focuses on drawing a single-line diagram and subsequently creating a hybrid photovoltaic system with energy storage, supplemented by a laboratory-use wallbox. The first part of the thesis provides a brief introduction to photovoltaics and presents various photovoltaic system types, as well as introducing different components of the hybrid photovoltaic system. Furthermore, the requirements for connection according to Annex 4 of the Distribution System Operation Rules and the Requirements for Generators directive are described. The second part of the thesis consists of the single-line diagram of the entire system and the module diagram of the R-DC/AC distribution board, based on which the entire system is assembled and connected. The conclusion of the thesis focuses on specifying how the distribution board is connected and describes the procedure for its installation. The measurement protocol for the specific distribution board R-DC/AC has also been prepared. The thesis also includes project documentation of the system, comprising a technical report and the mentioned diagrams.
