The Arkaroola Microgrid Project

Project at a Glance

“The S-5! PVKIT offered the perfect solution for the Arkaroola Microgrid. The ability to install this rooftop system without rails meant lower freight costs, maximising the available roof for solar, easier installation, and ultimately a reliable and better-looking rooftop system that blends with the stunning natural landscape. Rails are unnecessary on a metal roof, and once you understand how to approach cable management, it really is a more commonsense solution with a multitude of benefits, from protecting the roof to cost savings and simplified logistics and installation. It makes sense from all angles.”

—Sean LePoidevin, Project Manager, APEX Energy

The Situation & Results

Flinders Ranges is a remote area located 600km north of Adelaide, offering spectacular outback scenery with precipitous peaks and valleys, extreme topographic diversity, gorges and creeks. 

It is also home to the Arkaroola Wilderness Sanctuary, which showcases almost 2 billion years of geological history, excellent dark skies for astronomical observations and unique wilderness—and is under consideration for the United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage listing. This remote property in Australia must generate its own electricity and wished to transition from a reliance on diesel fuel to solar power energy.

They chose the S-5! PVKIT direct-attach, rail-less solar mounting solution for its lower freight costs, ability to maximise rooftop space for solar, ease of installation and its low-profile aesthetic appeal, given the surrounding natural landscape. The microgrid will reduce Arkaroola’s use of diesel by approximately 15,000L per year, a savings of 126,000kg of CO2 annually. At times, the village will operate on 100% renewable energy.

What Worked?

Installer APEX Energy utilized the S-5! PVKIT® – a rail-less solar mounting solution – along with the RibBracket™ attachment, providing a simple, secure method to “lay & play” PV modules with tested, engineered, cost-saving, direct attachment onto the ribs of the metal roof. Providing a faster and easier installation than a traditional rail system, S-5! turns the roof into a canvas, allowing panels to be installed anywhere on the roof, not just on roof purlins. The ability to design a landscape-oriented system enabled Apex Energy to maximize roof space and meant the arrays could be expanded by 7.3% to an impressive 61.6kWp of generation capacity.

Long-Term Outlook

The microgrid will reduce Arkaroola’s use of diesel by approximately 15,000L per year, a savings of 126,000kg of CO2 annually. At times, the village will operate on 100% renewable energy. In addition, the sanctuary owners can rest assured knowing the quality and reliability of the S-5! solution is engineered to outlast the life of the roof and carries a market-leading lifetime warranty.

S-5! Products Used

Using the PVKIT can save you up to 50% in:

  • Hardgoods - For example, a 50kW system requires about 150 lbs. (68kg) of parts vs. 970 lbs. (440kg) of rail.
  • Shipping - 80% lighter weight than rail mounting. Fewer than 3.5 lbs./kW (1.6kg) vs. 19.4 lbs. (8.6kg/kW) for rails.
  • Material transportation to the site - The 50 kW system delivers to the jobsite in the trunk of your car.
  • Lifting equipment not needed -  Equipment is only necessary for projects more than 500kW.
  • Installation time and cost - Locate modules as desired without customizing rails. Installation time is 30-50% less.
  • Aesthetically pleasing - Assembly is available in black architectural anodizing.

The RibBracket is the perfect attachment solution for specific North American trapezoidal, exposed-fastened metal roofs.These profiles are commonly referred to as R-Panel or PBR-Panel.
