Measuring system of photovoltaic panels efficiency
Hofman, Jiří ; Háze, Jiří (referee) ; Vaněk, Jiří (advisor)
This diploma thesis is focused on development and initial run of a measurement system whose aim is to measure photovoltaic panel efficiency. Experimental photovoltaic panel is installed outside the laboratory. Measurement system consists of the solar radiation measurement module (pyranometer), photovoltaic panel load module (panel power measurement) and panel climate measurement module. Data from measurement module is being captured via control computer for subsequent analysis of panel efficiency and climatic impacts on it.
Influence of shading on I-V characteristics of photovoltaic modules
Hájek, Tomáš ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
The presented thesis is concerned with the principles of Photovoltaics. It describes the basic principles of photovoltaic panels functioning and the unique periods of their developement. The thesis is also focused on the theoretical knowledge of equivalent circuits of photovoltaic panels. The primary objective of the thesis is a project of simulation environment in the programme Agilent VEE Pro 8.0. The programme enables a simulation of I-U characteristics of real photovoltaic panels.
Renewable energy sources in CR
Kozumplík, Ondřej ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech republic. It appears here the principal, use, potential and advantages and disadvantages of each type of renewable resources - water, wind and biomass. Then the use of solar energy for photovoltaic conversion to electrical energy is described in detail. At the end of this study is described one of the many recently build photovoltaic power stations in the South Moravia territory, the solar power station in Bzenec.
Resistance of the roof structure loaded with photovoltaic panels
Holoubek, Jan ; Bažant,, Zdeněk (referee) ; Strnad, Jiří (advisor)
The aim of the thesis is to verify the resistance of the roof structure loaded with photovoltaic panels. On the roof of industrial building of rectangular plan with dimensions of 26,5 x 24,5 m in Hlinsko, the investor decided to install photovoltaic panels. Preliminary diagnostic survey showed only flexural reinforcement in the field of all considered load-bearing elements. Bending strength was assessed by these structural elements: reinforced concrete slab, reinforced concrete beam, reinforced concrete grinder. Static calculation includes a minimum reinforcement of support and necessary shear reinforcement, which must be demonstrated by a detailed diagnostic survey. The structural analysis includes the assessment of reinforced concrete beam deflection after loading. All assessments were performed according to currently valid Eurocodes. The calculation showed that all supporting elements meet the bending resistance and deflection of the beam is smaller than the limit value laid down in the EC, so the roof of the hall can be loaded with photovoltaic panels.
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.
Business plan
Kočí, Pavel ; Krause, Josef (advisor) ; Hladký, Jan (referee)
The field of photovoltaics and solar power stations in the Czech Republic have experienced a huge developement in the past years thank's to very favourable conditions for enterprising in this line. These ones have changed a lot from the year 2011 and caused large changes in the photovoltaics. This thesis deals with business plan focusing on realization of minor solar power station. The main goal of this thesis is to compare on the basis of indicators of efficiency investment appraisal the real project from the year 2010 with the same fictitious project from the year 2011 and thus to show the impacts of legislation changes which should prevent from further growth of solar power stations in the Czech Republic. In this work photovoltaics is presented also generally so that it could provide comprehensive view of this branch.
Evaluation of Effectiveness Concrete Investmen Intention of Photofoltaic Power Station.
ŠVARCOVÁ, Petra
This diploma work is dealing with problems related to production of electrical energy in compliance with environmental protection and assessment of its production from non-renewable sources in reference to sources being renewable. The work puts emphasis on the importance and utilization of solar electrical energy. The sun is a source that will not get dried or mined out and will not stop shining. The goal of diploma work was to appraise the investment effectiveness with regard to a photovoltaic power station and assess the power plant influence in relation to classic sources for energy production and environmental protection. Within the diploma work, there were appraised three variants of the investment project which assumed life time longer than 20 years comprising conventional financial flows, surface size of 30 000 m2 and roughly required output of 1.5 MW. Single options were assessed upon economical evaluation regarding different ways of financing, in terms of price, output and guarantees provided by suppliers including the assessment of grant influence on the project effectiveness. Based on these data, the most suitable version for the investment project of building up the photovoltaic power plant was chosen. At the conclusion, it is possible to state that the photovoltaic power plant is very considerate towards the living environment in contrast to classical sources for electrical energy production, for example coal-fired power plants which heavily contaminate the environment, and nuclear power plants with risks of radiation escapes.
