Australian Solar Systems Interest Index: February 2022

SolarQuotes auSSII report - February 2022

Discover what Australian buyers were wanting in a solar power system last month in the February 2022 auSSII report.

Solar System Capacity (Size)

Where one of the following options was selected during the SolarQuotes quoting process: 3 to 5 kW, 5 to 10 kW, 10 to 15 kW, 15 to 20 kW, 20+ kW and “Fill Roof”, close to 79% chose the 5 – 10kW range in January, similar to December. Interest in the 3 – 5kW range dropped again to around 2.5% compared to 4% in December.

There was a big increase in the proportion of Australians wanting to make the most of their rooftop real estate for generating solar energy, with close to 12% choosing the “Fill Roof” option – up on December’s 9%.

System Purchase Timeframe

The proportion of prospective solar power buyers wanting to purchase a system immediately dropped from 28% in December to around 24% in January 2022; more in line with November, October and September last year (25%).

The uptick in particularly eager buyers in December was probably due to the looming rebate reduction in January. But as the rebate level is tied to installation date rather than purchase date, many quotes would have been taking into account a January install anyway.

The good news is even with the reduction in the national subsidy that slashes the up-front cost of installing panels, it’s still very generous. Learn more about the solar rebate.

Price Vs. Quality

12% of Australians were wanting a “top quality” (most expensive) system option in January, the same level as the previous three months. There was an increase in interest in systems offering a good balance of cost and quality; around 81% compared to December’s ~79% and therefore a dip in interest in a good budget system, down to 7%

Australian Solar Price Index

See what Australians are paying for systems on average – currently and historically – using the SolarQuotes Australian Solar Price Index. We’ll have a special report on average system costs and price per watt in January towards the end of this month.

Microinverter/Optimiser Interest

Again in January, 18% of Australians using the SolarQuotes service wanted more information about microinverters and optimisers. While adding to the cost of a system, these devices enable individual panel monitoring and may be helpful in some installation scenarios. Microinverters and optimisers are forms of PLO (Panel Level Optimisation).

Solar Energy Consumption Monitoring

Interest in advanced solar monitoring picked up again in January, up from December’s 37% to 39%. This popular optional extra can help you extract maximum value from your investment. Learn more about advanced solar monitoring

Battery Ready PV

A home battery can be retrofitted to any system, but we ask this question on the quoting form to give prospective installers a better idea if the customer is – at this point – considering adding energy storage down the track, as this can help inform system design.

Interest in battery-ready systems sat at around 5.5% in January (5% in December, 6% in November).

While few may be considering adding a battery in the future right now, they may change their minds as energy storage becomes cheaper. And there is a significant proportion of solar buyers considering a concurrent battery installation.

Solar + Storage Installation

As in December, around 18% of Australians using SQ’s service indicated they wanted a battery installed at the same time as their solar panels.

If you’re considering energy storage, be sure to read Finn’s “101” guides on understanding, buying and owning a home battery system that contain lots of useful advice and will help you to determine if a battery is right for you.

Intended Primary Battery Use

6% of requests in January including a battery installation indicated the primary application was for backup purposes (7% in December, ~6% in November, 5% in October).  34% want a battery mainly for minimising mains grid electricity consumption, same as December, and 60% for both purposes, up a touch on December.

Electricity Bills Pre-Panels

As for electricity costs prior to going solar, where noted, 46% reported bills between $500 and $1,000 a quarter – a fairly static figure. A touch over 11% were paying more than $1,000 a quarter compared to a bit under 11% in December and ~12% in November.

About Michael Bloch

Michael caught the solar power bug after purchasing components to cobble together a small off-grid PV system in 2008. He's been reporting on Australian and international solar energy news ever since.


  1. Malcolm Colless says

    There are two big issues not being properly addressed:
    1. All battery systems should be able to be recharged from solar during a blackout.
    2. All BEVs and PHEVs should have the ability to power the house at any time.

    Why pay $10000 for a backup battery when you already own a car with a much bigger battery?

    • Battery, solar and battery-solar systems that can operate when the grid connected/in household solar curtailment mode are indeed preferable to entirely grid dependent ones.

      Vehicles connected to dwellings should be included in the above principal. However, they still won`t power the dwelling when they are not connected to the dwelling. There are many dwellings in Australia that don`t have off-street parking, so are hard to connect to car batteries. There are many flats and units where the parking and dwelling are not connected and the car charging is likely to be separate from the dwelling electricity, making such connections harder. When a car is being driven, it won`t be connected to a dwelling. There are also households without cars at all.
