Newcastle falls into Zone 3 for the federal solar panel rebate. For each kW of solar installed, households and businesses can receive around a $272 rebate. For example, the rebate for an 8kW system in Newcastle is $2,200.
The federal battery incentive increases with every kWh of storage installed. A 13.5 kWh battery in Newcastle will attract a rebate worth around $4,196.

Solar savings and ROI in Newcastle
Even though solar is likely a sound investment if you have a property in Newcastle, it’s important to understand that the return on investment (ROI) is different for each household or business. There are many variables, so it’s worth using our solar payback calculator to get a grasp on the potential of solar at your property.
Typical payback for solar panels in Greater Newcastle
The average 4-person household uses 19 kWh of electricity per day in Australia. In Newcastle, this equates to a quarterly electricity bill of around $730. Depending on budget, roof space and future energy plans, a system size anywhere between a 5kW to an 8kW solar system will generate enough electricity to offset usage.
The graphic below shows results from our solar payback calculator for an 8kW system:
Payback on the 8kW system in this case is 5.4 years. Bear in mind, payback is a little faster on smaller systems, but lifetime savings are far greater with larger systems.
* Several assumptions have been made and it is best to input your own figures into our calculator.
Typical savings for solar batteries in Greater Newcastle
If we use the same case study above but add a battery, the results are quite different. The payback period for a panel and battery system in Newcastle goes out to 6.4 years but the savings increase by over $1,150. Of course, the system cost increases significantly too.
