Mount Majura Solar Farm - the National Capital Authority

Figure 3.1 Mount Majura Solar Farm Development Envelope depicted by the red shaded area (GoogleEarth image)3.2Site suitabilitySolar resource modelling based on satellite imagery correlated with nearby onsite solar resource datacollection has confirmed that there is an ample solar resource the project. There is an approx. average dailysolar exposure range of 15-18 megajoules per square metre (BOM 2010a).Site surveys assessing shading obstructions and other obstacles confirm that there is consistent solaraccess. The topography and geotechnical characteristics of the site are also suitable for a low impactmounting structure design and layout.The Proposed Works have been sited specifically to utilise existing grid connection infrastructure i.e.proximity to existing distribution line, and investigations into the grid connection capacity at the point ofconnection have confirmed the proposed capacity is appropriate to support the additional generationproduced by the proposed solar farm.3.3Proposed WorksThe Proposed Works are located adjacent to Majura Road, and will fill in the “road islands” between MajuraRoad and Parkway (which has already commenced construction). The Proposed Works are divided intothree sections. The Northern section covers Block 707, with Block 708 divided into an Eastern and Westernsection. An indicative layout of the site is shown in Figure 3.2 below.Error! Reference source not found. Figure 3.2 with the full site drawing provided in Annexure 2.The solar farm consists of the following main components: An array of solar photovoltaic (PV) modules, arranged in a series of long rows up to approximatelyfour metres above the ground and supported by a steel and/or aluminium mounting structure includingframing, pylons and foundations. A series of inverters and kiosk transformers distributed throughout the solar array. Electrical connections between PV array, associated monitoring and protection equipment and stringor central inverters via underground or frame secured cabling. A tracker actuation system (if applicable). Grid connection infrastructure to connect the project to the 11,000V distribution system via anoverhead or underground transmission line, including transformers, switchgear, protection, meteringand communications equipment.23Mount Majura Solar Farm – Works Approval Submission
