Solar Panels in Newcastle, NSW - Cost and Rebate Guide 2024

Australia is a strong supporter of solar energy and has demonstrated to be an ideal location for the installation of solar power systems. The switch to solar is becoming more popular daily, thanks to substantial government incentives, dropping prices of panels, and dependable feed-in tariffs.

Many households, businesses, and industries in Newcastle are installing solar power every day to reduce or eliminate power bills. The government’s Small-scale Renewable Energy Scheme aims at supporting homes to install solar panels and lower power bills.

The cost of solar panels is dependent mainly on the size of your solar panels. For instance, a 5kW system, the most popular solar system in Australian homes, goes for approximately $6,034.

The national average of solar systems of the same size is about $5,975, which means the cost of a 5kW system in Newcastle is on the lower end. This price is inclusive of the government rebate, which makes it affordable to install.

Government solar panel rebate in NSW

All homes in Newcastle looking to install solar panels will receive incentives through the federal government’s rebate program. These incentives will be provided through the Small-scale Technology Certificates program. These STCs are tradable certificates that you or your installer can exchange for a discount on the solar panels you wish to install.

The STCs you receive depend on your solar system’s size. For instance, a 5kW solar system receives 48 STCs and a rebate of $1,886 in NSW. Since NSW is in zone 3, its STC rating is 1.382, and the STC spot price is $39.30. The rebate varies from system to system and increases as the solar system size increases.

The following table shows the average rebate amount for various solar panels in NSW.

NSW Government State Rebates

Besides the federal government rebates, NSW offers rebates on solar for low-income households. This scheme aims to reduce the electricity bills for low-income houses, supporting up to 3,400 homes. These people can forego the rebate and get a 2.5kW solar system installed at zero cost.

This scheme will work better than the federal government rebates because all the beneficiaries will save over $600 annually from the electricity bill cost.

NSW is also providing an appliance replacement scheme for low-income houses. It offers 50% off the cost of a new refrigerator and 50% off for a new TV if these appliances have a high energy rating. This means the residents do not need to wait for solar installations to save power bills.

Solar system output in Newcastle NSW

When looking to buy a solar system, it is essential to know the output of the system you intend to install. Below is a table illustrating the different power outputs for different solar system sizes in NSW.

System SizeOutput

2kW8.6 kWh
3kW12.9 kWh

STC zone in Newcastle NSW

Newcastle is in zone 3, according to the STC zoning. This means it receives a rating of 1.382 for the STCs and a spot price of $39.30. Being in Zone 3 means the region gets a fair amount of sunshine but not as high as Zone 1 and 2 and not as low as Zone 4.

The STC zone matters a lot when calculating the rebates. The government uses the zone rating to provide rebates to all Australian residents. People in zone 1 thus get the highest rebates while those in zone 4 receive the least.

Solar Feed-in tariffs NSW

Solar feed-in tariffs are essential for all households with solar installations. This is because you may not exhaust all the energy your panels produce in one day. This means that the power you will not use will go to waste.

Instead of letting all that excess energy go to waste, you can translate it into money using the right feed-in tariff. You will feedback on all the surplus power and get incentives in return. Below are the best FiTs you should consider.
