Photovoltaic system for a family house
Hájek, Vojtěch ; Gregorovičová, Eva (referee) ; Toman, Filip (advisor)
This bachelor thesis explores the utilization of a photovoltaic system to reduce a family house's dependency on external electricity supply and achieve financial savings. Within the design section of the thesis, specific concepts of photovoltaic systems were developed. The primary objective is to minimize electricity costs while maximizing the use of renewable energy sources. These concepts are designed to achieve a major, rather than complete independence from grid electricity. Furthermore, the proposals were compared based on financial requirements, energy yield, and potential savings. The obtained results allow for the identification of a suitable proposal for a specific family house based on its energy needs and the owner's financial capabilities. Additionally, the study demonstrates the impact of subsidies on the overall return on investment in the project.

Study of influence degradation to fotovoltaic cells properties
Tulková, Tereza ; Sládek, Petr (referee) ; Zmeškal, Oldřich (advisor)
The thesis examines degradation of photovoltaic cells and modules. Degradation assessment was based on the data gathered from the photovoltaic system installed at the Pedagogical Faculty of Masaryk University in Brno, Poříčí 31. The research focuses on influence of external factors on the amount of power supplied to the grid by the system. Theoretical part of the thesis summarizes state-of-the-art knowledge about photovoltaic conversion and devices taking the advantage of the principle. The first part of the thesis describes production and application of photovoltaic cells and their impact on the environment. Second part of the thesis deals with the principle of photovoltaic conversion. Next part lists materials used for the production of photovoltaic cells and the process of encapsulation. The fourth part summarizes knowledge about degradation of photovoltaic panels. Experimental part of the thesis statistically analysis the data gathered from the above mentioned power plant. Influence of degradation factors (surface temperature of PV panel, air temperature, wind velocity and radiation intensity) on effectiveness of energy conversion was examined in particular. The published results can be applied on analysis of new projects and/or used for modification of production technological processes.

The development of the model of PV system for electric water heating
Sochor, Tomáš ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This thesis deals with designing of a model of a photovoltaic system for domestic water heating in program PSCAD. In theoretical part, an analysis of photovoltaic systems regarding their connection to electrical grid is made. Then a description of chosen concepts of photovoltaic systems for domestic water heating is made. Furthemore, a photovoltaic cell is described with regard to its mathematical description and influence of different parameters on its volt-ampere characteristics. Also, a common topologies of DC-DC converters are described. Control is also related to these converters, that is why a fundamental MPPT algorithms are described. Practical part deals with designing of chosen concepts of photovoltaic systems for domestic water heating in program PSCAD. A basic simulations with regard to behavior of these systems are performed, especially a relationship with respect to irradiance and temperature. Simulations are then discussed in the conclusion.

Optimalisation of thermal properties of solar cell modules
Dohnalová, Lenka ; Matiašovský, Peter (referee) ; Zmeškal, Oldřich (advisor)
The topic of presented diploma thesis is study of thermal properties structures of photovoltaic cells. The main goal of this thesis is study of ways of heat spreading from volume and planar materials (conduction, convection and radiation). Then it is needed to determine contributions of heat spread from laminated photovoltaic cell and compare them to results measured by transient pulse method, step wise method and with thermo-camera using. At the beginning of this thesis it will be needed to define heat and ways it’s spread. Heat is closely connected with temperature. That is reason why will be there spoken about temperature and methods of its measuring. Than there will be defined basic thermo-physical parameters of materials. Thermo-physical parameters of materials will be measured by transient methods that will be characterized later and by thermo-camera. This thesis deals with photovoltaic cells, so there will be described their structure, properties, utilization and way of their production. Subsequently after the definition of all needed terms the experimental part of this thesis will be introduced. It will be needed to characterize measured volume material and define its thermo-physical parameters. Using the pulse transient method, step wise method and thermo-camera there will be measured the thermal response of PMMA sample, nonlaminated photovoltaic cell and also samples of laminated photovoltaic cells. Findings of all described methods will be finally compared.
