Installation: The SA Power Networks Engineering Study defined the requirements for the project and Network Protection Unit, which included incorporating a ComAp Intellipro protection relay, current transformers for LGC metering and BMS integration, SolarEdge metering, a motorised main isolator and inverter circuit breakers. The 2 cubicle enclosure had to be split into individual cubicles to fit down stairs and through the entrance door to the Main Switchboard room. The power had to be switched off for the final AC connection after the pool closed to the public and power restored in time to bring the pool levels back to normal prior to public access the next day. Roof safety was required to be installed, including harness points, static lines, walkways and a restricted roof access point. Temporary edge protection was used for the duration of the installation, with safety protocols being adhered to at all times. A scissor lift was also used, with deliveries by crane trucks.

As the panels extend to all 4 roof faces, with the inverters located in the North West corner, the 46 strings installed required a mixture of 10mm, 6mm and 4mm DC cables to overcome voltage drop and efficiency losses within DC cables.

Working in with the Adelaide Councils Project Manager, Sustainability and I.T. departments, on site personnel and the solar consultant was a pleasure, with all facets of the project running smoothly.

Challenges: Working the installation project around the ‘Danpalon’ skylights by fitting one row of panels between the skylights and the steel profiled roofing sheets that varied in width, considering the expansion and contraction rate is different for these two materials. The original project scope changed after contract signing with discussions allowing changes by installing more panels on the Southern roof to ensure the solar output production was equivalent to the original partially elevated array on the North and Eastern roofs. The effective use of SolarEdge inverters coupled with optimisers and perfect string design helped overcome the shading challenges faced on this site. Working around weather and within project timeframes occurred with some challenges, but were overcome by working as a team.

Other iconic installations include the North Adelaide Aquatic Centre (400.62kW), Uni SA’s Pridham Hall,       over half a Megawatt on The University of Adelaide buildings. Other sites we have installed solar on include  various schools, councils, retirement villages, manufacturing facilities, prison and defence sites.
