The City of Sydney Council set a target of achieving a 70 per cent reduction in carbon emissions across the City of Sydney local government area and to have 25 per cent of its energy needs coming from renewable resources by 2030.

The City of Sydney Solar Project required ample innovation in the design and construction methodology as some of the sites contained:
• Heritage conservation
• Aesthetic architectural requirements
• Integration of systems into glass facades
• Elimination of high corrosion and high wind issues for sites near water
• High voltage requirements
• CBD access requirements

During the design stage, Solgen liaised with the town planning department in order to ensure the aesthetic integrity of each site was maintained. All planning approvals were arranged and any heritage restrictions were identified and adhered to.

Solar power project details

Key facts about this solar system project:

Client: City of Sydney Council
Location: Central and South Sydney City
Solar system peak capacity: 1.25MWp
Panels: Trina Solar Poly 250W

Schott 100W Amorphous panels

Inverter: SMA Inverters
Green savings: 2,073 tonnes of emissions per annum
Solar electricity generated: 1,958MWh per annum

Structural engineers were consulted to ensure that each roof would bear the load of the PV system. Where ballast systems were used, the structural engineering team identified the ballast weight necessary to meet the down force required at each panel individually.

Solgen liaised with the Distribution Network Provider (DNSP) on each site to identify special protection requirements, implement the protection according to the Solgen design and perform a witnessed safety testing.

Where Building Integrated Photovoltaic (BIPV) is planned, Solgen liaised with a glazing professional in order to design a custom framing and mounting system and specified custom BIPV modules from the preferred solar panel manufacturer.

Benefits

The City of Sydney Solar Power Project is estimated to deliver a 4.5 per cent reduction in the City’s overall greenhouse gas emissions and 12.5 per cent of the City’s own energy requirements.

The installation of solar panels supports the target of the City of Sydney Council to reduce the City’s overall greenhouse gas emissions and use renewable resources. The key benefits of the solar installations include:

  • Green savings over 2,073 tonnes of emissions annually.
  • Produces 1,958,139 kWh per year of electricity from renewable sources.
  • Reduces the need to invest in new coal-fired power stations and network upgrades.
  • Demonstrates positive action on climate change to community.
