POSSIBILITY OF PRODUCING PHOTOVOLTAIC ELECTRICITY ON BALCONY FENCE IN PIROT, SERBIA

In urban environments, PV panels are usually affixed on available buildings, but they can also be included in the initial architectural design of the constructions. PV panels mounting on/as balcony fences become frequent solution for creating PV systems in buildings. The idea of decentralized production and storage of electricity very close to the point of use represents an additional benefit. In this paper, the possibility of using PV panels in urban conditions, within the home installations of individual residential consumers with the placing of panels on the balcony fence, is analyzed. A detailed simulation of the complete PV system in the PVSYST software was used for the analysis of different mounting options for PV panels on the balcony fence. For an individual consumer from the “Household type 3” category with an annual consumption of about 6000 kWh, the installation of PV panels with a total power of 1650 Wp was analyzed. Different variants of installation of PV panels were simulated for the case of two different tilt angles (0o (vertical position) and 60o) and three different azimuthal orientations (south, east and west). Self-consumption is modeled through typical daily profiles, taking into account seasonal variation for a given type of consumer. The obtained results show that in the investigated PV system, photovoltaic energy can cover from 15.84% to 29.48% of considered household’s self-consumption, depending on the tilt angle of the PV panels on the balcony fence and their azimuthal orientation.
