PV power plant Zorenci II
The Zorenci II plant has a peak capacity of 765 kilowatts peak (kWp). It is connected to the local 20 kV medium-voltage grid belonging to Slovenian electricity supplier Elektro Ljubljana with highly efficient SMA inverters. The grid connection point is close to the photovoltaic park, which was installed on what was previously unused land. Easements ensure that the cables required for connection can be laid over third-party property. We have also secured all other rights and authorisation to build power plants, such as planning permission and leases for the land.
Installed modules
The photovoltaic modules used in the plant are supplied by the Austrian company KIOTO Photovoltaics GmbH in St. Veit an der Glan. Manufactured to the highest quality standards, they have a nominal power of 210 Wp – 215 Wp (watts peak) per module. The KIOTO photovoltaic modules are certified to IEC 61215:2005 IP 65 by TÜV Rheinland (German product testing agency) and thus meet the world’s most stringent test standards for photovoltaic products.
Power plant operation
Operation specialists ENcome Energy Performance are responsible for organising and running the power plant. In order to keep a constant check on the photovoltaic power plant, we installed a 24/7 monitoring system which sends all the plant’s performance parameters online to the control station in Klagenfurt. This enables the operator to detect even the slightest deviation and take the necessary corrective action immediately.
