Why Off-Grid System?

Installing an off-grid solar system has many advantages. One significant benefit of a complete off-grid solution is lowered energy costs. Utility companies typically charge consumers excessive grid connection fees in remote areas.


An off-grid solution offers a versatile option for homeowners and businesses alike. Whether your property is not yet connected to an energy network or you're considering disconnecting, this solution is ideal. It’s particularly advantageous for worksites and remote locations where diesel fuel is currently used for power generation.

Other good reasons to install an off-grid solution are:

  • Reduction in diesel generation usage and costs
  • No expensive grid connection charges
  • Scalable up to 1000KW
