Technical and Economic Aspects of Photovoltaic Conversion of Southern Poland
2014
Abstract The article presents the results of a 13-year tests and analysis of performance and energy and electrical charge yield for typical photovoltaic modules made of different absorbers. Modules were installed on the south wall of Opole University building (at kard. B. Kominka Street). Registered in this period (2001-2013) values energy and charge of tested modules are presented in reference to 1 Wp their nominal power and to 1 m2 of PV modules. Their annual and monthly distributions, with particular emphasis on the seasonal changes of its parameters and phenomena of aging and degradation of the PV modules structure were shown. In the final part of the article was presented an economic a…
Analysis of Solar Energy Resources in Southern Poland for Photovoltaic Applications / Analiza Struktury Zasobów Energii Słonecznej Obszaru Polski Poł…
2013
Abstract The article presents an analysis of the resources and the structure of the solar energy in the area of Southern Poland on the basis of complete meteorological data from the AGH University of Science and Technology in Krakow in 2009. An analysis attempt of its use for photovoltaic conversion using different modules with different spectral characteristics of absorbers was made. These latest methods for characterizing the structure of solar energy resources such as: distributions throughout the year: sky clearness or cloudiness indexes, the average values of photon energy (APE) and the contents of the useful fraction (UF) of the solar spectrum, are not yet widely known and used as in …
Impact of the Solar Irradiation Angle on the Work of Modules with Spherical Cells - Simulation
2018
Abstract The main purpose of all PV modules is to convert solar energy into electricity, but in the era of building integrated photovoltaics, there are additional opportunities to use them. The use of them as a composite of architectural structures in the form of facade cladding, roofing, stained glass windows or noise barriers on highways, in addition to generating electricity embellish also the aesthetic value of the facilities. However, these atypical their use, cause that the modules should have quite different properties then in the traditional application, which is related to their unusual way of positioning. Particularly for structures such as the modules made of spherical cells with…
Cheap Sensor Made of Multicrystalline Silicon for Insolation and Temperature Measurements
2016
Abstract In the paper some results on measurement of insolation and „real” cell’s temperature carried out with use of standard silicon solar cells are presented. Two identical cells are applied in such a sensor. Short circuit current of one cell is a direct indication of insolation value and open circuit voltage of the other cell is indirect indication of actual sensor’s temperature but in this case more complex formula must be used for temperature calculation.
Photovoltaics: solar energy resources and the possibility of their use
2016
Abstract In this paper possibilities and limits of use of solar energy (like the best efficiencies of PV cells, world records and ‘notable exceptions’) were shown. Also some new ideas and concepts in photovoltaics (like new photovoltaic power plants or energy storage) were presented. Additionally authors try to predict development of solar power industry.
