A boost of solar for Bridgestone

Owned by the global Bridgestone Corporation, Bridgestone Earthmover Tyres is Australia’s leading supplier of off-road tyres for mining, construction, earthmoving, forestry agricultural and industrial applications. As a company, Bridgestone works to achieve a high standard of environmental awareness and to incorporate sustainable practices across the board.

Strengthening sustainability practices

The 100kW solar power installation at Bridgestone Forrestfield will assist the company in contributing towards a greener future for generations to come.

Solgen had to adhere to stringent structural guidelines when planning the installation of the solar power system due to the age of the Bridgestone Forrestfield factory. This limited the available roof space for solar panels. Western Australia also has a zero-export utility regulation allowing no energy to be fed back into the grid.

Taking into consideration these constraints, Solgen Energy Group developed a tailored 100kW solar power solution for Bridgestone Forrestfield.

Solar power project details

Client:Bridgestone Earthmover Tyres Pty Ltd
Location:Forrestfield, WA
Date completed:December, 2015
Solar system peak capacity:100kW
Panels:384 x Trina Solar 260W Modules
Inverter:4 x SMA Sunny Tripower 25000TL
Green savings:120 tonnes of emissions per annum
Solar electricity generated:170MWh per annum

The tailored solution was flush mounted in order to maximise available solar capacity on the roof and associated electricity output. A 9m clearance safeguard was implemented to separate the solar panels from the roof edge to ensure the system could withstand the expected wind load for the region and structurally comply with all relevant standards.

The design also avoided placing solar panels close to the various roof obstacles, such as the skylights and utilities, to eliminate any possible shading.

All design and installation decisions made by Solgen were unique to the factory and were implemented to exceed the value of the solar power system. The estimated output for the Bridgestone Forrestfield project is 170 MWh in the first year with an annual performance degradation below 0.7 per cent.


The installation of a 110kW photovoltaic system will:

  • Generate an estimated energy output of 170 MWh annually.
  • Offset up to 120 tonnes of CO2 each year.
  • Demonstrate the organisations commitment towards carbon reduced operations.
  • Represent the potential financial benefits that could be achieved by renewable energy systems.
