Analysis of effect of solar radiation concentration on the thermal insulation degradation in the flat roof construction
Židek, Ondřej ; Běžel, Jakub (referee) ; Žák, Antonín (advisor)
The master´s thesis analyzes influence of direct and reflected solar radiation to heat strain and degradation of thermal insulation in the flat roof construction. In many building was a problem in a significant degradation of thermal insulation made from expanded polystyrene in the vicinity of glass surfaces. To determine the causes of this problem, it was necessary to study and test the properties of building materials and the physical nature of the effect of solar radiation on the building structure. In the introductory section lists the cases of buildings with degradation of thermal insulation and existing knowledge on this issue. The theoretical part describes the technical properties of thermal insulating materials used in the flat roof construction, nature and division of solar radiation, optical laws of light reflection and physical theory to explain the technical thermal behavior of building materials and structures. The last part describes a practical model and analyzing measured data in thermal stress in the flat roof construction. The practical part also determines the importance of different influences configuration structures using to dynamic simulations. At the end of the practical part they are validated theoretical knowledge obtained by analyzing data from a practical model.

The power of solar radiation falling on a photovoltaic module
Kaliyev, Alexey ; Jandová, Kristýna (referee) ; Křivík, Petr (advisor)
The work is focused on the problem of the solar radiation power impacting on a photovoltaic module. In the theoretical part, the possibilities of using solar energy in renewable energy sources, especially in photovoltaic panels and solar collectors, were discussed and presented. Then the materials on the use of solar energy in these sources were reviewed. In addition, the three main components of incident solar radiation on a photovoltaic module or solar collector were described. Finally, the method for calculating the position of the sun across the sky was discussed and presented, as well as the method for calculating the various components of incident solar radiation on a photovoltaic module.

The acquisition of energy data
VOJČ, Zdeněk
The bachelor thesis deals with the acquisition and processing of energy, specifically with the measured values of electricity production from the solar power plants. The work focuses on the entire process, from production, continual measurement of energy meters, meteorological data processing, and analysis of the measured data replacement values for the data processing needs of market operator. The result is a system design and software application that cover entire process with a focus on replacing the missing measure data through the analysis of meteorological data.
