Australian Solar Systems Interest Index – August 2019

auSSII solar report - August 2019

The latest auSSII report provides a statistics snapshot of what Australian solar buyers were wanting in a solar power system during July 2019.

PV System Sizing

69% of those who submitted their details for quotes through our service and had a system capacity in mind requested pricing details for a 6kW or larger solar system (67% in June and 68% in May). 3kW systems are going the way of smaller systems before them, with just 3.5% expressing interest in this size. As was the case in June, 32% were unsure on capacity and requested guidance on system size.

Quality Vs. Price

Close to 12% wanted a “top quality” (most expensive) system in July; around the same level as June (May ~13%). As for a preference for a system offering a balance of quality and price; this was up a little at 81%, and 7% wanted details on a good budget solar power system (8% in June, 7% in May).

Advanced System Monitoring

We ask the question on our quote form:  “Would you like consumption monitoring?” as a solar monitoring system is a wise option. It seems many Australians considering going solar understand the value in advanced energy monitoring, with 63% selecting “yes” in July. This dropped back a little from June’s 64%, May’s 67% and April’s 65%.

Solar Battery Ready Systems

Interest in “battery-ready” solar power systems has continued to slowly drop – 23% in July, 24% in June, 26% in May and 27% in both April and March. While systems installed these days can generally be considered “battery-ready”, we ask this question to assist installers who will be supplying quotes with system design.

Solar Energy + Battery Installation

Just 5% registered their interest in having a solar battery installed at the same time as their PV system; well down on the 7% we saw in June and May’s 8%. This may be due to household budgets getting tighter or the growing realisation that at this point in time, solar batteries have a negative impact on system payback in the vast majority of cases. The best bang for buck comes from installing more solar panels.

Battery Sizing

Where there was interest in a concurrent battery installation and capacity was specified, just over 17% requested pricing and details on a 1-5kWh system in July (19%  in June, 20% in May, 21% in April), 51% a 5-10kWh battery (43% in June, 45% May, 43% in April) and 32% a 10kWh+ battery (38% in June, 35% in May and April). 58% wanted guidance on battery sizing in July, up from 55% in June.

Battery Application

A little under 5% wanted to use a solar battery primarily for backup purposes (June and May around 3%, April 6%). 47% were after energy storage to minimise grid electricity consumption (June 45%, May 48% ), while 48% were interested in both applications (52% in June, 49% in May, 47% in April).
