330 kW Solar Power Plant – Liri Confectionery Factory, Prizren, Kosovo

A 330 kWp rooftop solar PV system installed at the Liri confectionery factory in Prizren, comprising 612 solar modules with an expected annual energy production of approximately 300 MWh.

The project was executed through a structured, engineering-driven installation process, covering mechanical installation, electrical works, and final system commissioning.

Precise mounting of PV modules on rooftop structure, ensuring alignment, secure fixing, and compliance with mechanical load requirements.

The installation began with the precise mounting and alignment of PV modules across the rooftop surface. Special attention was given to module positioning, fixing integrity, and layout consistency to ensure both mechanical stability and optimal energy yield.

Electrical installation works included disciplined cable routing using metallic cable trays, with clear separation of DC conductors and proper cable management. This approach ensures mechanical protection, long-term durability, and ease of maintenance under industrial operating conditions.

The system integrates Sunergy USA Works modules (590 W and 450 W) and three KSTAR string inverters. Commissioning activities included inverter setup, verification of electrical parameters, and full system activation, ensuring stable and reliable operation from the initial start-up.

System commissioning and verification of KSTAR inverters, including operational checks, parameter validation, and system activation.

The final system configuration reflects a well-organized PV field, optimized according to available roof geometry and system design constraints, resulting in a uniform and efficient module layout.
