Off Grid Solar Power

Off Grid Solar Power

Off grid solar power systems, also known as Stand-Alone-Solar-Power-Systems (SAPS) are a type of solar energy system which has no reliance on electrical networks at all.

This type of solar power system is common in remote areas or areas where power connection is too difficult and expensive to consider. The main drawback to this type of system is the upfront capital cost.

Cost for an off-grid solar power system is typically in the range of $10,000 – $50,000+.

For a typical Brisbane home, using power the same as on-grid a rough cost estimate would be around the $35,000 mark assuming that STC rebates are available at $38 each. This price is after rebates.

The high cost of off-grid solar power systems is mainly due to the high cost of batteries, the battery management system and the added complexity of this type of system.

Should you get off grid solar power?

Are you sick of paying “service charges” to power companies even if you’ve got solar panels? If you’re fed up with the ever increasing electricity price trends and want a simple solution to becoming free with your own power setup, then off grid might be for you. The main reasons for going off-grid are:

  • Sick of paying for network equipment
  • Sick of paying service fees and getting power outages
  • High cost initially just to connect to the grid
  • Remote location – not able to get grid power

The first 2 reasons aren’t “critical” but more and more people are getting sick and tired of paying rising costs for little benefit. Power works the same as it did 100 years ago, yet the costs have risen extremely higher.

What are the parts of an off-grid solar power system?

This can vary a bit depending on what type of setup you have. For a home setup that runs 240V appliances, you would need:

  • Solar panels
  • Inverter/charger
  • DC charge controller
  • Battery bank
  • Electrical wiring

Or some combination of the above. One great way to setup an off grid solar system is to have it AC coupled. This means you have a normal grid connected solar power system and then you have an inverter/charger to manage a battery bank and a generator if necessary.
