Design, Analysis, and Implementation of Photovoltaic Systems

This paper presents the technical design and simulation-based performance analysis of a photovoltaic system
implemented on the rooftop of a small industrial facility located in the central region of North Macedonia. The
system includes 136 monocrystalline solar panels with a rated power of 545 W each, connected through two 36
kW Sungrow inverters and configured to efficiently support industrial energy demands.

Simulations were performed using PVsyst software based on real meteorological data from METEONORM, with
calculated energy yield, monthly generation profiles, system losses, and performance ratio. The PV system
demonstrated high efficiency, with a projected annual generation of 98 MWh and an average performance ratio
exceeding 87%.

The technical solution also considers optimal panel orientation, tilt angles, cable dimensioning, and protection
measures, in accordance with engineering standards. The project highlights the viability of rooftop PV systems in
industrial applications as a reliable and sustainable energy source.
