The demonstrator site in Ljubljana will be set up at the Faculty of Electrical Engineering (FE), which is a member of the University of Ljubljana (UL). The members of the University of Ljubljana are spread out in many buildings across the city of Ljubljana. The Faculty of Electrical Engineering is situated at Tržaška cesta in Ljubljana and consists of four interconnected buildings with enough roof space for about 200 kW photovoltaic power plant.
There is enough space on the Faculty of Electrical Engineering’s horizontal roof for a PVPP with a capacity of around 200 kW depending on the exact PV module power. Parts of the roof are already covered with different kinds of photovoltaic panels, which are being used for research purposes. The physical location of the PVPP is on the roof of four different faculty buildings.
This is an excellent location for a PVPP due to the ample amount of sunlight that shines on the site. There is also plenty of space for additional panels on facades if needed in the future. Installing a PVPP at this location will help to reduce the University of Ljubljana’s carbon footprint and contribute to awareness of all stakeholders of the faculty on the production of electricity from renewable energy sources.
The Faculty of Electrical Engineering is the perfect place to install a PVPP due to its prominent location and its importance in educating students on renewable energy sources. Most important of all – students can see the power plant in action and learn from it directly.
The installation of the PVPP will proceed in phases taking into account the interest of participants and available funding. In the initial phase, a 39 kW power plant will be installed regardless of funding from the energy community. This section will be aimed to demonstrate the PVPP, raise awareness and increase interest in PV. In this section modules will be mostly installed under a 10° inclination in an east-west orientation (65° NE and 245° SW, exactly) to maximize available roof space. The whole construction will have a slightly different inclination to conform to the roofs (flat, 7° N, 7° S). Also, different module types (PERC, TOPCon, SHJ, IBC) will be installed. The variability will provide a lot of monitoring data regarding different orientations and different technologies, which will be made available to citizen scientists for research purposes.
Further expansion is possible on additional roofs (27 kW, 10° incl., E-W (-25°); 38 kW, 14° incl., 65°W and 115°; 87 kW different orientations)
