With a growing wave of new solar installations around Sydney, The University of Sydney were looking to offset their high electricity bills in a way that would not only reduce their costs, but would also contribute to their commitment to sustainability and reducing their carbon footprint. As a result, they sought to install almost 2000 solar panels across 14 buildings to increase their solar energy capacity by 512kW.
Having already completed projects for the university at their Abercrombie Precinct as well as their Queen Mary Building, Solgen Energy Group was awarded the engineering, procurement and construction of this roll-out in conjunction with managing contractor for the project, Lend Lease. This was based on our experience in delivering high-quality, engineering-based solar solutions with an experienced project management team.
|Client:||University of Sydney|
|Date completed:||December, 2016|
|Solar system peak capacity:||512kW combined|
|Panels:||Trina Honey 260W|
|Inverters:||SMA Sunny Tripower|
Wanting an optimal system, the installation incorporated a number of key components. This included top-of-the-line Trina Solar Honey Poly 260W panels and German engineered SMA Tripower inverters both known for their durability and efficiency as well as Tigo smart modules to reduce the effects of shading in some locations. For longevity, all metal materials used externally were comprised of stainless steel – this included rooftop boxes and cable trays. On top of these components, the roll-out also had a range of roof shapes and sizes each with their own structural requirements. As a result, there were different mounting systems used including klip-lok, screwed and ballast – so each site was designed and installed uniquely to the roof requirements. To ensure the systems were performing at their peak, Solgen also provided the University of Sydney with a performance guarantee and the systems were connected to the university’s Advanced Utilities Management system.
Being a highly operational site, there were strict WH&S requirements that had to be adhered to from both the University of Sydney and facility manager, Lend Lease as they each have their own strict set of guidelines. As a result, crane lifting was not permitted and at some locations labourers had to be hired to carry equipment to the roof. In addition, some of the installation had to be scheduled for weekends so as to reduce any disruption to staff and students and mitigate risks. Permanent roof safety equipment and permanent roof access equipment also had to be provided to ensure there was a high level of safety to not only stand on the roofs but also to access the roofs.
Despite these strict guidelines the project was delivered on time and on-budget with minimal disruption. As a result, the installation of 512kW of solar energy has reduced their on-grid energy consumption by
634,682kWh/year and has reduced their carbon emissions by 444 Tonnes annually.
The installation of 14 solar power sites at the University of Sydney will:
