Canberra, ACT is a great place to go solar in Australia, thanks primarily to the ever-improving economics of solar panel installations. This article takes a look at the some of the key considerations for going solar in Canberra, including system pricing, energy yields and incentives available to system owners.

The benefits of solar power in Canberra, ACT

Harness the power of the sun in the Australian Capital Territory

Getting the best deal on solar PV anywhere in Australia–including Canberra–means first understanding how a system benefits a home or business. Solar panels only produce electricity during sunlight hours, and how much electricity is generated depends on the intensity and duration of the sunshine.

The average Canberran rooftop receives an annual average of about 4.3 hours of sun per day. This number fluctuates seasonally (higher in summer and lower in winter). Estimated daily generation figures for different size systems based on 4.3 sun hours are detailed below (minus a 15% efficiency loss).

Solar PV system pricing in Canberra

Solar Choice regularly publishes articles with indicative pricing for PV systems in Australia’s capital cities (including Canberra) in our Solar PV Price Index.

The table below shows how solar system price trends for Hobart over the last four years. The prices are in dollar per watt ($/W) format and segmented by popular system sizes (1.5kW – 10kW).

Solar system generation vs electricity consumption in Canberra

The right system size for a Canberra resident is the one that produces just enough electricity to meet daytime electricity needs. This will depend on the household or business in question. Solar systems in the ACT are best-suited for those who use a significant portion of their power during daylight hours (read more about solar self-consumption).

Federal Government Solar Rebates for Canberra

Significant up-front incentives are available from the federal government. Technically speaking, this discount comes in the form of ‘small-scale technology certificates’ (STCs), which utility companies and other liable entities are obligated to purchase under Australia’s Renewable Energy Target scheme. STCs significantly reduce the cost of having a solar PV system installed, typically by as much as 55-70c per watt, depending on the market price for STCs.

Am in ACT and looking for someone to look at my solar system we believe the readings haven’t changed since the last bill and last quarter we didn’t get discount which indicate the system might be faulty or something . Thanks

Hi Adam. Who installed your system? They’d be the best ones to reach out to as a first port of call.

I have a PV panels on my roof – 48 of them. All is almost perfect EXCEPT for the leaking roof due to a shoddy installation. Roof leaks only during a heavy rain and if there is a moderate to strong wind. By the way, the roof was retailed about one year prior to installation of the PV panels, therefore, it did not leak before.
DO you have any advice who can correct the installation here in the ACT?

Hi Rikitan,

Can you check back with the installer who put the system up? That would be the best place to start.

Hi . I have 2kw solar system at the moment. Looking to put batteries in. But l have been told that the system needs to at lease 5 kw. The panels are 12off 175kw with 2.4 sma inverter . Would it be better to upgrade to 5kw inverter and add extra panels
or just put another 2.5kw system on? I believe that the panels i have are not made anymore ( schott 175 ) so can you add larger panels together with the old system?
Can you please direct me in the right direction.
thanks steve

Hi Steve,

We recommend speaking with an accredited solar installer for more precise details, but here is our general guidance in response to your questions.

-You could potentially have batteries with a 2kW solar system, but the battery bank would have to be quite small for your solar to be able to fill it up completely. There are lots of battery storage products out there, however, so make sure that you consider more than the product you’ve been recommended.

Two resources of ours that you might want to make use of:

-Our Battery Storage Sizing & Payback Estimator Tool will let you explore a variety of system sizes & configurations to help you give yourself a general idea of what you need. (Its limitations are explained on the calculator page.)

-Check out our Battery Storage Product Performance Comparison Tool, which contains a wide range of products currently available on the market and their respective sizes.

About upgrading & swapping the inverter: If your existing inverter is still under warranty, you might be better of having a new, separate system installed alongside the existing one. If it’s getting on in its years, however, you might want to consider upgrading it and adding new panels. The new, larger inverter will need to be able to take in two different strings of panels (ask how many maximum power point trackers the inverter has – your installer should know). Another option if your inverter is getting old is to replace it with a new, similar size inverter and have any new panels added to your home with microinverters, which are installed on the roof inside or next to the new panels. The advantage of doing so is that you wouldn’t need to worry about adding a second central inverter – plus you’d be able to add as many or as few new panels as necessary.

If you’re looking for quotes on solar or battery storage systems, please fill out the Quote Comparison Request form to the right of this page. By doing so, you’ll be able to compare prices on a range of products & system sizes from installers in your area.

Hope this helps you out!
