There is a lot of discussion about solar supply chain issues putting upward pressure on Australian system prices-this is what we see on the ground (or more accurately, on the roof).

The following table shows the prices (cost per watt) paid by systems of all system sizes in October and all rebates and subsidies compared to September and October 2020.

This is an updated chart of the national cost per watt chart (all system sizes) dating back to October 2019:

The chart below shows the historical cost per watt of a 6.6kW solar system, which is currently generally considered entry-level:

This information is generated by the SolarQuotes Australian Solar Price Index, an interactive tool that shows the average price of solar power system installations in each state and across Australia. To understand things in more detail, you can dive into the pricing of various system sizes and brands of solar panels and inverters.

The October data comes from Australians who have submitted comments from solar installers. This includes the review of installers not related to the SQ network; so the quality of the system will vary. Given that the index is updated with the emergence of new comments, the above figures may change.

With the exception of Western Australia, Capital Territory, and Tasmania (the latter two may be related to how many records we have), in this case, prices seem to be fairly stable between September and October — and compared to last year It's also pretty good compared to October. Some states.

But it needs to be kept in mind that the cost of solar energy has generally been declining, so changes in this trend prove that solar panel supply problems are having an impact.

According to reports, some installers also grabbed any solar panels they could get. Perhaps some of the more commonly used well-known brands are being replaced by less popular cheap brands, and it remains to be seen how this will play out in the next few years. If you want to buy a solar power system, please pay special attention to any system components in the quotation-research the brand.

Australians also have a tendency to buy larger and larger systems (such as 10kW)-larger systems are usually cheaper in terms of cost per watt. Having said that, compared with September, the price of a 10-kilowatt system in October seems to be higher. The 6.6kW system is cheaper.

As for when the supply/cost issue will be fully resolved, we have heard everything from very optimistic before the end of the year to very pessimistic in 2023.

The pricing in November and December will be interesting because the solar rebate (actually an upfront discount) will be reduced again on January 1. Because the subsidy is partly based on the system installation time and some installers have already booked it by the end of this year, the quotations of these installers will reflect this.

If you are considering postponing the installation of the panel for some reason, please consider:

Every quarter that every household or business postpones the installation will pay a quarter of the electricity bill that is much higher than in other cases-and this may quickly increase to a very substantial amount.
