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

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.
