Why Off-Grid


One of the greatest advantages of having a complete off-grid solar system in Queensland is reduced energy expenses, as utility providers generally charge rural consumers exorbitant grid connection fees.


An off-grid system is ideal if your building does not have access to the local electrical grid. And if you want to disconnect from a power grid to achieve energy independence, it’s also possible. 


Off-grid solar systems are ideal for worksites and remote homes, buildings or facilities, especially if you’re currently relying on diesel fuel to keep operations going.


Other reasons for installing an off-grid system include:

  • Protection from power outages
  • Reduction in diesel generation usage and costs
  • No expensive grid connection charges
  • Scalable up to 76 kW (IEC) or 61kW (UL)

GES offers an extensive range of off-grid solar solutions for a wide array of applications, including small homes, commercial buildings, and large-scale agricultural operations.
