PV power plant Madrino

The Madrino PV plant has a capacity of 1,996 kWp and is connected to the local 20 kV medium-voltage grid belonging to Bulgarian electricity supplier EVN Bulgaria. Madrino is a ground mounted PV system with a fixed tilt. We have obtained all the required permits.

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 (watts peak) per module. The KIOTO modules are certified to IEC 61215, IEC 61730, MCS and 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, a 24/7 monitoring system will be installed 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.
