The University of Technology Sydney is aiming to move towards sustainability by minimising its environmental impact, promoting social justice and equity and maintaining financial viability. As a result, the university has committed to a 30% reduction in Greenhouse Gas Emissions on 2007 levels by 2020-21. In order to achieve this goal, the university has instigated a number of initiatives including the installation of a 127kW system on the rooftop of their Aerial Function Centre in Building 10 of their city campus.
Solgen Energy Group was awarded the solar engineering, procurement and construction for the 127kW system. After a competitive tender process, we were chosen due to our ability to meet and exceed the specific requirements as requested. This included a system design that maximised the net savings over the life of the system, procurement of a durable system that required minimal operation and maintenance, and construction of an array in a way that will minimise the impacts on the university including interruption to operation, roof efficacy and aesthetic impact of the array.
|Client:||University of Technology Sydney|
|Date completed:||August, 2017|
|Solar system peak capacity:||127.8kW|
|Panels:||Talesun Mono 300W|
The original tender requested contractors supply polycrystalline panels with a 280W output due to their size given the limited roof area. With Solgen’s relationship with quality suppliers we were able to supply monocrystalline 300W panels of the same physical size. This meant more output and more energy savings for the university and thus a better ROI.
Construction of the array was complex to manage due to the many intricacies involved in installation on a seven-storey CBD building with limited roof access due to its operations as a function centre. While a crane was originally arranged to transport goods to the roof, because of tight timeframes, Solgen had to arrange to bring site components via the goods lift then scissor lift to the roof while maintaining minimal impact to the building’s operations. As a result, communication and coordination were particularly crucial for this project as in addition the function centre was also completing a floor-wide refurbishment in parallel to the installation of the solar system. With our experienced project managers working closely with all key stakeholders the project was deemed a success with all roof works completed within two weeks – a key objective for the UTS Facilities Management Office and the Aerial Function Centre.
The resulting system installed will see the university save over $35,000 each year with a 20% ROI. It will also contribute significantly to the university’s sustainability objectives with the system estimated to produce 175MWh of energy each year and offset 198 tonnes of carbon emissions annually, which is the equivalent of taking 42 cars off the road each year.
The installation of a 127kW photovoltaic system is expected to:
