Measuring station for the system of the remote energy supply
Dočekal, David ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
This thesis is focused on the creation of measuring workplace for remote power supply system. This is the measuring of the workplace, engaged in the processing of measured data, the production of electrical energy made by a photovoltaic panel and wind turbines. In the theoretical part, the reader is familiar with the issue of renewable energy sources. The first chapter is about the energy of the wind. Here is described the emergence of the wind, the basic division of wind power, through the production of electrical energy to the measurement itself. The second chapter deals with the solar energy. This chapter describes the emergence of the solar energy, photoelectric effect, description of characteristic features and related evaluation of the photovoltaic panel. The reader learns the basic distribution photovoltaic panels here and their manufacturing. The third chapter is devoted to measurement methods and specifying the basic conditions for the evaluation of the operation of wind turbines and photovoltaic panel. In the fourth chapter describes the basic data on individual facilities, which have been selected for this thesis and the involvement of the measuring site. There is also included wind power JPT-100 photovoltaic panels A-130 anemometer TX20ETH, pyranometer SG420 and temperature sensor PT100. Measuring software is described in the fifth chapter. In the last chapter, contains the experimental measurements in the selected time interval and the actual evaluation.

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.

Solar Radiation Measurements
Chvátal, Michal ; Pikula, Stanislav (referee) ; Beneš, Petr (advisor)
The Bachelor‘s thesis discusses design and verification of an inexpensive method for indicative measurement of direct and diffused solar radiation. The reason for the measurement of solar radiation is the estimate the heat gain of buildings. In this paper the difference between thermoelectric generator and cooler is described. There is also described how to choose a suitable module for solar radiation measurement. The design of the measuring circuit and the construction of sensor are also described. Eventually the measured values are compared with the values from the commercial pyranometer SG420.

Solar Radiation Measurements
Kokeš, Miroslav ; Krejčí, Jakub (referee) ; Beneš, Petr (advisor)
The aim of this thesis is to design a moderate matrix sensor equipped with photodiodes BPW34 which is used to measure direct and diffused solar radiation. The theoretical framework of the thesis is focused on the analysis of solar radiation, influencing phenomenon and devices used for measuring solar radiation. Practical part of the thesis includes design and selection of suitable parts followed by construction of the device and its testing in operating conditions. The irregularity in design of the sensor caused the error which led to the failure in evaluating of measurement. The overall solar radiation data was measured and evaluated. The conclusion is dedicated to the evaluation of results and possible future plans to redesign the device in order to correct the measurement of all required data.

Equipment for measuring of solar radiation intensity
Bobalík, Lukáš ; Dolenský, Jan (referee) ; Stojan, Radek (advisor)
This project offers a proposal and a solution of an equipment for measuring of solar radiation intensity. It lists reasons why to measure intensity, contains fundamentals of photovoltaics, deals with how electric energy is obtained from a solar radiation and how the intensity of solar radiation affects the power output of photovoltaic devices. The project also deals with prime facts about 4 – 20 mA current loop and serial RS-232 communication. Proposed design is based on usage of the pyranometer CMP 21, a PIC microcontroller and a current loop to create a device which gathers data and transfers them to a PC for further processing.
