Bridgestone is working to achieve a high standard of environmental awareness which includes the addition of a 30kW commercial solar power system designed and installed by Solgen Energy.

Throughout the planning finalisation phase, Solgen Energy’s engineers implemented value engineering methodologies to ensure the most cost efficient project was delivered to Bridgestone.



Solar power project details

Key facts about this project:

Client:Bridgestone Earthmover Tyres Pty Ltd
Location:Mt Isa, QLD
Date completed:May 2015
Solar system peak capacity:30kWp/td>
Panels:115 x Trina Poly 260W modules
Inverter:1 x SMA Sunny Tripower 25000TL

1 x SMA Sunny Tripower 5000TL

Green savings:58.4 tonnes of emissions per annum
Solar electricity generated:56.4MWh per annum

Taking into consideration these constraints, Solgen Energy developed innovative solutions to tackle the challenges presented by this project.

The roof of the Mt Isa facility has a pitch of around 5 degrees. After conducting an initial assessment of the proposed site, Solgen Energy’s engineers were able to recommend a 30kW flush mounted solar system as the best layout for the client.

Solgen Energy also allowed for access ways between the solar panels and around the arrays to ensure that the panels and roof can be easily maintained in the future. Solgen Energy also avoided placing panels close to the various roof obstacles, such as the skylights and utilities, to eliminate any shading issues and the strings of panels were implemented in the most symmetrical and logical fashion.

The roof of the site was originally constructed using Corrugated Iron, Trim Dek metal and the roof contains screw lines. As such, Solgen Energy fastened the framing clamps by utilising the exact holes where the existing roofing screws were already located. The result being that no new roof penetrations were made.

The system uses 115 x 260W Trina Solar panels and 2 x SMA Sunny Tripower Inverters incorporated with SMA monitoring. While the majority of solar panels currently being implemented on commercial projects are 250 Watts each, for this project Solgen Energy utilised the new and improved 260 Watt Trina Solar Honey modules. The 260W is more powerful and efficient than the 250W resulting in a higher quality system,fewer panels and lower installation costs.

The estimated output for this solar power project is 54,630kWh’s in the first year with an annual performance degradation that is expected not to exceed 0.7%.

The final agreement included the design, engineering, installation and commissioning of the completed solar power system. Completed in May 2015, this system now provides Mt Isa Bridgestone with many years of clean energy from the sun.


The installation of a 30kW photovoltaic system will:

  • Generate an estimated energy output of 54.6MWh annually
  • Offset up to 58.4 tonnes of CO2 each year
  • Demonstrate the organisations commitment towards carbon reduced operations of Australian businesses.
  • Represent the potential financial benefits that could be achieved by renewable energy systems.
