ANALYSES OF PV SYSTEMS OF 1 kW ELECTRICITY GENERATION IN BOSNIA AND HERZEGOVINA

Abstract

Abstract:The paper focuses on the analysis of PV systems of 1 kW electricity generation in Bosnia and Herzegovina. At the beginning, some information about solar energy and PV systems, renewable energies policies and physical-geographic position and climatic characteristics in Bosnia and Herzegovina are provided. Based on PVGIS program, the results of calculation of the yearly average values of the optimal panel inclination, solar irradiation on the horizontal, vertical and optimally inclined plane, ratio of diffuse to global solar irradiation, associated turbidity, average daytime temperature and 24 hours average of temperature for 27 cities in Bosnia and Herzegovina are shown. The paper also outlines the total yearly sum of global irradiation per square meter received by the modules of the optimally inclined fixed 1kW PV system, optimally inclined one-axis and dual-axis tracking 1kW PV systems as well as total yearly electricity production of different types of PV 1kW system for 27 cities in Bosnia and Herzegovina, obtained by PVGIS. The comparison is provided for the total yearly electricity production of different types of 1kW PV system with monocrystaline silicon, CdTe and CIS solar modules, respectively, for 27 cities in Bosnia and Herzegovina. Calculations performed by PVGIS program have shown that irrespective of the type of PV systems, most electrical energy in Bosnia and Herzegovina can be generated by means of PV systems with CdTe solar cells. Some practical data and considerations given in this paper can be used by a customer or company interested to invest in the PV sector in Bosnia and Herzegovina.

Simulation of photovoltaic systems electricity generation using homer software in specific locations in Serbia

“…Over time these systems will reduce the need to increase the capacity of the transmitting and distributive lines [5,6,[8][9][10][11]. PV system consists of solar modules, inverter converting DC into AC and switches and related connections giving the generated power into the grid net.…”

Energy efficiency of photovoltaic solar plant in real climate conditions in Banja Luka

“…Also, available literature provides scarce information on the energy efficiency of PV solar plants in the Republic of Srpska, and there are not many studies presenting all factors affecting the efficiency and operation of the entire PV system. Besides, up to now there were no investigations, in real conditions, of the meteorologial parameters' influence on the energy efficiency of PV solar plants in the Republic of Srpska [2][3][4][5][6][7][8][9]. In October, 2012 on the roof of the ASARS building in Banja Luka a fixed, on-grid PV solar plant was installed.…”

ASSESSMENT OF THE POSSIBILITIES OF BUILDING INTEGRATED PV SYSTEMS OF 1 kW ELECTRICITY GENERATION IN BANJA LUKA

“…Efficiency of the commercial monocrystalline silicon solar cells is 15%, of polycrystalline silicon is around 12%, of amorphous silicon is around 5% and from CdTe and CIS is around 8%. Monocrystalline and polycrystalline silicon solar modules are more suitable for the areas with predominantly direct sun radiation, while solar modules of thin film are more suitable for the areas with predominantly diffuse sun radiation [7], [9], [12−14].…”
