Economic aspects use of energy of photovoltaic plant
Cerman, Marek ; Procházka, Jiří (referee) ; Macháček, Jan (advisor)
The major topic of this master‘s thesis is to create a complex model of general photovoltaic power plant (PVP). First chapters are engaged in research of photovoltaic. Growth of globally installed power and analysis of situation in Czech Republic are described in this section. The spectrum of conditions is introduced, from current legislative framework up to local Sun radiation. The actual technologies and their advantages are depicted, especially rate of utilization of energy. Expected trends of future development of conversion efficiency are mentioned, with prediction of production costs of photovoltaic. In context with those aspects, the question of grid parity achievement arises. The own assembled model of photovoltaic power plant has been created in Microsoft Excel. The mathematical apparatus is described in a separate chapter, individually solving technical part, which main result – the amount of yearly generated electricity, is applied for economical calculation. Final results are the usual economic indicators, mainly: Net Present Value (NPV), Internal Rate of Return (IRR), Levelized Cost of Electricity (LCOE). There is series of aspects defined by user in the model which may impact the amount of produced electricity and economics of user’s project, such as use of loan, replacement of converters, operational costs etc. These aspects are frequently neglected by project sellers. In the end, intended photovoltaic power plants of 2.75 kWp and 28.98 kWp are simulated by the model in real conditions of 2013. Sensitivity of impact of both proposals to the aspects mentioned above has been analyzed. In the conclusion the achieved results are summarized and the key factors which determine the PVP’s economic efficiency are assessed.

Development of the complex simulator of the solar irradiance and its cooperation with the PV module
Petrov, Roman ; Vrána, Michal (referee) ; Ptáček, Michal (advisor)
The main point of this thesis is the extension of the complex solar radiation simulator, the creation of new functionalities, and the cooperation of this complex simulator with the PV power plant. This work builds on the work done in the area of solar radiation modeling. The thesis deals with the continuation, or improvement of some shortcomings, removing shortcomings, such as fixing the beginnings and ends of the simulation, correcting the calculation of sunrise and sunset, but also adding different types of clouds, combinations of different preset cloud situations, or data input, and more. These deficiencies are found in the bachelor's thesis "Complex Simulator of the solar irradiance", and PSCAD is the main tool in this work. Another important point of this work is the realization of the simulation where an improved solar radiation simulator works in cooperation with a model of a photovoltaic panel or a PV power plant, respectively. It has different operating states created in PSCAD. These include, for example, cloud crossings, both over the entire power plant and only partial. In addition, there are experiments that prove the fact that the direction of the incoming cloud plays a role in the power of the PV power plant.

Single-family house
Tóthová, Patrícia ; Jelínek, Petr (referee) ; Struhala, Karel (advisor)
The bachelor's thesis deals with a project documentation for a building permission of a newly-built single family passive house located in municipality Dolní Břežany in the Central Bohemian Region. The plot is accessible by local road and is slightly sloping. The thesis has two parts. The first part presents structural and architectural design and also building physics assessment. The second part presents the design of building services – ventilation, heating, mechanical, electrical, plumbing and rainwater management. The house has two above-ground stories. On the ground floor there is a utility room, storage space, toilet, home-office and kitchen which is open to the dining area and living room. On the first floor there are situated three bedrooms, master’s bedroom, bathroom, toilet and walk-in-wardrobes. The vertical load-bearing structure of the house is sand-lime block masonry. External walls are insulated with graphite polystyrene ETICS. The house is built on foundation strips. The floor structure consists of filigree slab with a concrete screed. The house has a flat green roof. The house has mechanical ventilation. It is heated by floor heating with an earth-water heat pump as the heat source. It also has photovoltaic panels providing electricity. The rainwater is collected from roofs and paved surface and is used for watering a garden. The excess rainwater is infiltrated on the property. The Energy Performance Certificate was calculated. The project documentation is developed using BIM methodology.
