Australian Solar Systems Interest Index: April 2021

auSSII solar report - April 2021

Our latest auSSII report provides an insight into what Australia solar buyers were wanting in March 2021 when requesting quotes via SQ.

Solar System Sizing

Where a system size was selected, 85% of Australians using SQ’s service requested solar quotes for systems 6kW or greater, the same as in February. Overall, a bit over a third weren’t sure and wanted advice on system installation sizing.

PV Purchasing Timeframe

Close to 20% were ready to purchase a PV system immediately, down on February’s 21% and January’s 23%. But there is still plenty of enthusiasm for having a system installed quite soon, if not straight away. In March, 97% were considering signing on the dotted line anytime from now to within 3 months.

Cost Vs. System Quality

12% of Australians using the SQ service in March were wanting pricing on “top quality” (most expensive) solar power systems, back to the level of January after dipping to 11% for February. 79% were after a system offering a good mix of quality and cost, and around 9% a good quality budget system.

Microinverters/Power Optimiser Option

A whisker over 13% were interested in learning more about optimisers and microinverters in March – these devices are types of Panel Level Optimisation (PLO) that can be beneficial in some installation scenarios such as partial shading.

Solar Energy Consumption Monitoring

A very useful optional extra for a PV system is advanced solar monitoring. This enables a system owner to not only monitor how much solar energy is being generated but also how it is being consumed in the home. In March, approximately 42% were interested in consumption monitoring.

Battery Ready Systems

While  installing a battery may not be on the cards immediately, it can be handy to let a prospective installer know you’re considering storage down the track so this can be factored into system design. But really, all systems are “battery ready”. Interest in battery-ready systems crept up to 6% in March, from 5% in February.

Solar + Battery Installation

While on the topic of batteries, interest in having energy storage installed concurrently with solar panels dropped back again in March to a little under 12% (February ~14% and 15% in January). Before plonking down a great wad of cash on a battery, try out SQ’s solar and battery calculator – that will show the financial returns on solar and storage separately.

Battery Capacity Preference

For those who wanted quotes on a solar and battery system and had a battery capacity in mind:

  • 1 – 5 kWh: ~11% (February ~13.5%, January ~16%)
  • 5 – 10 kWh: ~43% (February~51%, January ~51%)
  • 10 kWh +: ~46% (February ~35%, January ~33%)

A significant shift again from small to large batteries. Another big change last month was the proportion of enquirers wanting advice on battery system sizing; down from 58% in February to 47% in March.

Primary Battery System Application

Just over 7%  indicated backup would be the primary use of their battery (6% in February and January). A little more than 38% were interested primarily in minimising electricity consumption from the grid (39% in February and 42% in January), and again, 54% for both backup and minimising grid electricity.

Electricity Bill Costs

Prior to installing solar panels and where electricity costs were known, 45% were paying between $500 and $1,000 per quarter on average (49% in February and 48% in January). As in February and January, approximately 11% were seeing electricity bills of more than $1,000 a quarter.
