The master’s thesis deals with study the effectiveness of operation of photovoltaic power station. The theoretical part describes the legislative steps that led to the development of photovoltaic power stations, not only in Czech Republic but throughout Europe. The following is a review of the issue of photovoltaics, which includes the development of photovoltaics in the world, research of photovoltaic power stations in the Czech Republic and technology of photovoltaic power stations. At the end of the theoretical part is a list of methods to evaluate efficiency investments. The practical part includes a description of the selected photovoltaic station Zakřany 5.4 MWp, financial projection and economic evaluation of the real operation and there is also explicit evaluation of the economic efficiency of the project.. The comparison of the projection and the real operation and the possible negative influences affecting the power station are in conclusion.

The work deals with development and assembly of ultrasonic airflow measurement module for measurement of air flowing around photovoltaic panel. This system allows quantification of photovoltaic panel air cooling. The work contains development of sine wave generator, bridge amplifier and receiver with passive band pass filter, amplifier and comparator. It also deals with digital part realization. This digital part is formed by Renesas 78K0R microcontroller on demo board. The last part of this work contains testing of the whole system in aerodynamic tunnel and on photovoltaic panel installation.

This project solves the problem of cooling the photovoltaic cell. Solar cell was modeled according to a real model in SolidWorks, and subsequently created the model was simulated in SolidWorks Flow Simulation and Ansys Fluent. The use of both systems allow a comparison of their possibilities in the field of heat transfer and their suitability for the case. The conclusion summarizes the first results and outline further developments cooling design to optimize the performance of the solar cell.

The Thesis topic deals with the design and implementation of the system for photovoltaic power stations property administration. Due to the scope of the property administered, a solution using geographic information systems has been selected. Functionality of the designed system with data defined for the photovoltaic power stations were verified in the pilot operation. The results of the pilot operation proved efficiency and effectivness of the designed system.

The aim of this thesis is the design and building services systems in buildings with energy close to zero. The thesis 2 variants were designed heating and DHW. In variant 2 is considered with the photovoltaic system to generate electricity that is used up mainly in the building. It is part of the thesis experiment, whose aim was to monitor and evaluate the structure of electricity consumption in the residential unit.

The purpose of this dissertation is to design the dual-axis solar tracker carrying the concentrator photovoltaic panels. The preamble of the dissertation shortly examines a photovoltaic cells development up to concentrators and the common support structures of solar power plants. The second part focuses on the engineering process itself. It includes the choice of the variant that suits best the requirements, the calculations of wind load and design of the various joints. The conclusion part is devoted to the evaluation, economy analysis of the construction and proposals for improvements.

This diploma thesis deals with the accumulation of electrical energy in the scale of small house. The theoretical part describes the various ways of storing power. The practical part is devoted to the design and comparison of electrical energy accumulation for a particular house.

Thesis designs an autonomous timber house RD Zeleny Vrch. The building is intended as a residential dwelling for a four-member family, the build up area is 120 square meters and it’s located in the land register held at Babice u Rosic. A topic is firstly researched in literature review which sums up features of the autonomous and low-energy houses and environmental impacts. Construction systems and technologies used in the design are researched next. The project then contains a building solution in a state of documentation for building permission, thermal properties calculations and technological solutions for maintaining of house autonomy and user comfort. As last the price of the building is estimated. Discussion evaluates designed project regarding used building materials, used technologies, user comfort and possible alternative solutions.

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.

Dissertation deals with fuzzy knowledge base supporting investor’s investment decision into the photovoltaic technologies during pre-design phase, when the engineering solution is not known yet. Probably, majority of investors have particular image about the cost and risk coming from investment into the photovoltaic technologies. However, this image is limited to the restricted knowledge areas of each investor. During the period, when the investor is planning investment into the costly photovoltaic technologies at complex, vague and heavily qualified information about the conditions and risks of investment in the specific region, where the environment is constantly inconsistent and multidimensional, it is possible to solve this complex situation with fuzzy logic. This dissertation is focusing on creation of fuzzy knowledge base with selected installed projects in Europe since 2008 and its use with expert system. Furthermore, is covering the definition and description of the variables, which are included in the investor decision making process. The complete designed architecture of the fuzzy knowledge base is tuned and five projects with different size are tested. The fuzzy knowledge base consists of overall 24 variables and 187 statements.
