Tenders Are Invited For Construction Work For Research Buildings – Photovoltaikanlage in Germany

Work Detail

Construction Work For Research Buildings – Photovoltaikanlage. A Pv System (Orientation: East-West) Is Planned In Combination With Extensive Green Roofs. The Nominal Power Should Be Approx. 275 Kwp, Two Inverters Of 110 Kva Each Are Planned. In Addition, A Facade Pv System With Xxx Kwp Is Being Built, For Which Two Inverters Of 110 Kva Each Are Also Provided. Both Pv Systems Feed Directly Into The Nshv In The 1St Basement Of The Fubic Via A Separate Ac Supply Line For Each Inverter. The Solar Yield Of The Pv System Is Recorded In The Balance Using Rlm Meters. Due To The High Power Requirements Of The Fubic In Combination With Summer Power Peaks (Cooling), Which Correlate With The Pv Yields, Pv Surpluses Are Only To Be Expected In Regular Operation In The Summer Months When There Is Simultaneously High Solar Radiation And Low Electricity Requirements. In Combination With Battery Storage, A Self-Consumption Rate Of 100% Is Achieved. Due To The Mathematically Exclusive Internal Consumption, The Pv System Is Operated Outside The Eeg. There Is No Feed-In Into The Public Power Grid; It Is A Zero Feed-In. A Grid Feed-In Does Not Occur During Regular Operation And Is Technically Prevented Outside Of Regular Operation. Due To The Active Connected Power Of The Pv Systems Including Battery Storage With More Than 270 Kva, The Vde-Ar N 4110 Technical Connection Rule For Medium Voltage Applies.
