Neubau eines Busbetriebshofes- PV-Anlage Überdachung

TENDER DESCRIPTION

The subject of this invitation to tender is the complete delivery, installation, testing and commissioning ready for operation of a grid-connected photovoltaic power system on the roof covering over the bus parking bays of the new bus depot in Freising. The roof covering has a roof area of approximately 34.5 × 57.5 m with a roof pitch of approximately 35°. On this area, a total of 480 bifacial photovoltaic modules in double-glass design with a rated power of at least 450 Wp per module are provided. The total output of the PV generator is approximately 216 kWp, with a generator area of around 959 m². Because a fire wall is arranged centrally within the roof covering, the PV generator is divided into two largely independent sub-systems. Each sub-system receives its own three-phase string inverter with multiple independent MPP trackers. The routing of cables across the fire wall is to be avoided. The inverters are installed in the area of the roof covering and/or on the support columns provided for this purpose. The final wiring configuration as well as the sizing and routing of the cables are to be determined by the contractor as part of its workshop and installation planning…
