Australian Solar Systems Interest Index – September 2019

Discover what Australians were wanting in a solar power system (and battery storage) in our latest auSSII report, covering August 2019.

Solar Power System Capacity

Of the thousands of Australians who used our service in September, 70% had a system size already in mind. Of those, a whopping 72% were interested in a solar power system 6kW or larger. This figure has continued to creep up – 69% in July and 67% in June. Interest in 3kW systems continues to wane, with just over 3% selecting this system size (3.5% in July).

Timeframe For PV Purchase

Those eager to purchase PV immediately increased to 19% last month, compared to 18% in July. Again in August, 84% wanted to buy a solar power system anytime from now to within 3 months.

Quality And Price Considerations

Just on 13% had their sights set on a “top quality” (most expensive) system in August; not much change there between July/June’s 12% and May’s 13%. 79% expressed interest in a system with a balance between quality and price (81% in July) and 8% were after a good budget system – this number has been bouncing around 7-8% for quite a while.

Solar System Monitoring

Finn strongly recommends investing in an advanced solar monitoring system (here’s why) – and there has been a lot of interest from Australians in this optional feature. 66% wanted details in August, up from July’s 63%.

Battery Ready Solar Systems

Interest in “battery-ready” solar power systems had been dropping each month for some time but leveled out at 23% in August. While most solar power system installations can generally be considered “battery-ready” these days, this question is on our quoting form to help prospective installers with system design when preparing quotes.

Solar PV + Energy Storage

Close to 5.5% expressed interest in having a solar battery installed concurrently with their solar panels, up a smidge on July’s 5%. It’s encouraging to see Australians avoiding batteries at this point for whatever reason, as the best return on investment is to be had by installing more solar panels.

Solar Battery Capacity

For those who were set on getting quotes for solar batteries and had a capacity in mind, 19% asked for pricing on 1-5kWh capacity, 44% for 5-10kWh and 37% for 10kWh+. The proportion of those wanting guidance on battery sizing dropped from 58% in July to 53% in August.

Primary Use Of Battery

Just 3% were wanting a battery for backup purposes (5% in July). 46% had minimising grid electricity consumption as their primary reason, while 51% wanted a battery for both applications.

Quarterly Electricity Costs

Where quarterly electricity costs were known, 45% selected a range of $500 – $1,000 (49% in July). Those hit with average quarterly bills of more than $1,000 rose from July’s 9% to 11% in August.
